Updated Jan 16th, 2016.
\n\n# Getting Started\n\nThere are a lot of module loaders out there: Require.js, JSPM using System.js, to name a few.\n\nEventually the JavaScript community will come around and land on a winning module loader. My guess is Webpack, or something very similar.\n\nGo with Webpack. Webpack provides an elegant and multi-featured approach to module loading. It does everything I wanted it to do, and more. Really, a lot more.\n\nLet's try it out. We'll setup a project using Webpack, including ES6 transpiling & Sass loading. In this example, we'll setup an Angular based project using Webpack.\n\n
![Webpack & Angular](https://shmck.herokuapp.com/content/images/2015/04/webpackAngular.png)
\n\nFree free to load the [basic project from Github](https://github.com/ShMcK/WebpackAngularDemos/tree/master/Part1).\n\n## File Setup\n\nFile Structure:\n\n```\nroot\n├── app\n│ ├── core\n│ │ ├──bootstrap.js\n│ │ └──vendor.js\n│ │\n│ ├── index.html\n│ ├── index.scss\n│ └──index.js\n├── .jshintrc\n├── node_modules\n└── package.json\n```\n\nThis should be the bare minimum required to check if everything is working.\n\n/app/index.html\n\n```markup\n\n\n\n \n Webpack & Angular\n\n\n

Angular is working: {{1 + 1 === 2}}

\n\n\n\n```\n\n/app/index.js\n\n```js\nalert('loaded!');\n```\n\n\n## Webpack\n\n### Setup\n\nLet's create a `package.json` file to get started.\n\n```shell\nnpm init\n```\nAgree to whatever defaults.\n\nWe're going to need a few basic dev-dependencies to get started with webpack.\n\n```shell\nnpm install -D webpack\n```\n\nWebpack will also require a [webpack configuration file](http://webpack.github.io/docs/configuration.html): `webpack.config.js`. Make the file and add the following:\n\n/webpack.config.js\n\n```js\n'use strict';\nvar webpack = require('webpack'),\npath = require('path');\n\nvar APP = __dirname + '/app';\n\nmodule.exports = {\n\t// config goes here\n};\n```\n\nWebpack is a lot easier than it looks. You just need to provide an `entry` and an `output`.\n\nNotice `bundle.js` is the only script we needed to load in our `index.html`. Everything will go into that bundle.\n\nLater you can have multiple bundles for easy lazy-loading and code-splitting.\n\n/webpack.config.js\n\n```js\nmodule.exports = {\n\tcontext: APP,\n\t entry: {\n \t\tapp: './index.js'\n\t},\n\toutput: {\n\t\tpath: APP,\n\t\tfilename: 'bundle.js'\n\t}\n}\n```\n\nWe now have a module loader.\n\nLet's build our bundle in the terminal.\n\n```shell\nwebpack\n```\n\nThis should create the `app/bundle.js` file. Check it out. It's mostly a bunch of `webpack__require` statements.\n\n### Webpack-Dev-Server\n\n[Webpack-dev-server](http://webpack.github.io/docs/webpack-dev-server.html) is a quick and easy Node.js/Express/Socket.io app that creates your `bundle.js` file on the fly and reloads it on changes.\n\nInstall it as a dev-dependency.\n\n```shell\nnpm install -D webpack-dev-server\n```\n\nBut wait, there's more!\n\n\n### Hot Mode\n\nHot mode = live-reload of modules. No need to reload the entire project on every change, just load what changed. It makes sense and it's awesome.\n\nIt's not much work either. Update your webpack.config file.\n\n/webpack.config.js\n\n```js\nentry: {\n app: ['webpack/hot/dev-server', './index.js']\n }\n```\n\nYou may want to install `webpack-dev-server` globally. Otherwise you'll have to run it the long way: `node node_modules/.bin/webpack-dev-server --content-base app/ --hot`\n\nRun it.\n\n```shell\nnpm install -g webpack-dev-server\nwebpack-dev-server --content-base app/ --hot\n```\n\nOpen up `http://localhost:8080/webpack-dev-server/`.\n\nIt's hot.\n\n/app/index.js\n\n```js\nalert('hot-loaded!');\n```\n\nIt updates amazingly fast. Again, unlike Gulp or Grunt, Webpack only needs to re-compile the module that changed.\n\nTargeted reloading might not be important to you now, but as your project grows in size & complexity it becomes increasingly useful.\n\n### Quick Start\n\nIf you're used to using Gulp or Grunt, you probably like the time saving `gulp serve`, `grunt serve` shortcuts for running your app.\n\nThis can be accomplished with `package.json` [scripts](https://docs.npmjs.com/misc/scripts).\n\n/package.json\n\n```json\n\"scripts\": {\n \"start\": \"webpack-dev-server --content-base app --hot\"\n }\n```\n\nNow run `npm start`. Again, the app can be found at `localhost:8080/` by default, or `localhost:8080/webpack-dev-server` for the hot-module version.\n\n#### Bootstrap Angular\n\nI like to bootstrap Angular, rather than adding `ng-app=\"app\"` into the html.\n\n/app/core/bootstrap.js\n\n```js\n/*jshint browser:true */\n'use strict';\n// load Angular\nrequire('angular');\n// load the main app file\nvar appModule = require('../index');\n// replaces ng-app=\"appName\"\nangular.element(document).ready(function () {\n angular.bootstrap(document, [appModule.name], {\n //strictDi: true\n });\n});\n```\n\nNotice `require('angular')`? That replaces adding `\n\t \n\t \n\t */\n\tfunction copy(source, destination) {\n\t var stackSource = [];\n\t var stackDest = [];\n\n\t if (destination) {\n\t if (isTypedArray(destination)) {\n\t throw ngMinErr('cpta', \"Can't copy!

To run multiple applications in an HTML document you must manually bootstrap them using\n\t * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.\n\t *\n\t * You can specify an **AngularJS module** to be used as the root module for the application. This\n\t * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It\n\t * should contain the application code needed or have dependencies on other modules that will\n\t * contain the code. See {@link angular.module} for more information.\n\t *\n\t * In the example below if the `ngApp` directive were not placed on the `html` element then the\n\t * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`\n\t * would not be resolved to `3`.\n\t *\n\t * `ngApp` is the easiest, and most common way to bootstrap an application.\n\t *\n\t \n\t \n\t
\n\t I can add: {{a}} + {{b}} = {{ a+b }}\n\t
\n\t \n\t \n\t angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {\n\t $scope.a = 1;\n\t $scope.b = 2;\n\t });\n\t \n\t \n\t *\n\t * Using `ngStrictDi`, you would see something like this:\n\t *\n\t \n\t \n\t
\n\t
\n\t I can add: {{a}} + {{b}} = {{ a+b }}\n\n\t

This renders because the controller does not fail to\n\t instantiate, by using explicit annotation style (see\n\t script.js for details)\n\t

function\n\t *\n\t * @description\n\t * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.\n\t *\n\t * If jQuery is available, `angular.element` is an alias for the\n\t * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`\n\t * delegates to Angular's built-in subset of jQuery, called \"jQuery lite\" or \"jqLite.\"\n\t *\n\t *
jqLite is a tiny, API-compatible subset of jQuery that allows\n\t * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most\n\t * commonly needed functionality with the goal of having a very small footprint.
\n\t *\n\t * To use `jQuery`, simply ensure it is loaded before the `angular.js` file.\n\t *\n\t *
**Note:** all element references in Angular are always wrapped with jQuery or\n\t * jqLite; they are never raw DOM references.
\n\t *\n\t * ## Angular's jqLite\n\t * jqLite provides only the following jQuery methods:\n\t *\n\t * - [`addClass()`](http://api.jquery.com/addClass/)\n\t * - [`after()`](http://api.jquery.com/after/)\n\t * - [`append()`](http://api.jquery.com/append/)\n\t * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n\t * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData\n\t * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n\t * - [`clone()`](http://api.jquery.com/clone/)\n\t * - [`contents()`](http://api.jquery.com/contents/)\n\t * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`. As a setter, does not convert numbers to strings or append 'px'.\n\t * - [`data()`](http://api.jquery.com/data/)\n\t * - [`detach()`](http://api.jquery.com/detach/)\n\t * - [`empty()`](http://api.jquery.com/empty/)\n\t * - [`eq()`](http://api.jquery.com/eq/)\n\t * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n\t * - [`hasClass()`](http://api.jquery.com/hasClass/)\n\t * - [`html()`](http://api.jquery.com/html/)\n\t * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n\t * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n\t * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter\n\t * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n\t * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n\t * - [`prepend()`](http://api.jquery.com/prepend/)\n\t * - [`prop()`](http://api.jquery.com/prop/)\n\t * - [`ready()`](http://api.jquery.com/ready/)\n\t * - [`remove()`](http://api.jquery.com/remove/)\n\t * - [`removeAttr()`](http://api.jquery.com/removeAttr/)\n\t * - [`removeClass()`](http://api.jquery.com/removeClass/)\n\t * - [`removeData()`](http://api.jquery.com/removeData/)\n\t * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n\t * - [`text()`](http://api.jquery.com/text/)\n\t * - [`toggleClass()`](http://api.jquery.com/toggleClass/)\n\t * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.\n\t * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter\n\t * - [`val()`](http://api.jquery.com/val/)\n\t * - [`wrap()`](http://api.jquery.com/wrap/)\n\t *\n\t * ## jQuery/jqLite Extras\n\t * Angular also provides the following additional methods and events to both jQuery and jqLite:\n\t *\n\t * ### Events\n\t * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n\t * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n\t * element before it is removed.\n\t *\n\t * ### Methods\n\t * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n\t * retrieves controller associated with the `ngController` directive. If `name` is provided as\n\t * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n\t * `'ngModel'`).\n\t * - `injector()` - retrieves the injector of the current element or its parent.\n\t * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n\t * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to\n\t * be enabled.\n\t * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n\t * current element. This getter should be used only on elements that contain a directive which starts a new isolate\n\t * scope. Calling `scope()` on this element always returns the original non-isolate scope.\n\t * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.\n\t * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n\t * parent element is reached.\n\t *\n\t * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n\t * @returns {Object} jQuery object.\n\t */\n\n\tJQLite.expando = 'ng339';\n\n\tvar jqCache = JQLite.cache = {},\n\t jqId = 1,\n\t addEventListenerFn = function(element, type, fn) {\n\t element.addEventListener(type, fn, false);\n\t },\n\t removeEventListenerFn = function(element, type, fn) {\n\t element.removeEventListener(type, fn, false);\n\t };\n\n\t/*\n\t * !!!

\n\t * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return\n\t * a number representing the offset (in pixels).

\n\t * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from\n\t * the top of the page to the element's bottom will be used as offset.
\n\t * **Note**: The element will be taken into account only as long as its `position` is set to\n\t * `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust\n\t * their height and/or positioning according to the viewport's size.\n\t *\n\t *
\n\t *
\n\t * In order for `yOffset` to work properly, scrolling should take place on the document's root and\n\t * not some child element.\n\t *

\n\t *\n\t * ## Comprehensive Directive API\n\t *\n\t * There are many different options for a directive.\n\t *\n\t * The difference resides in the return value of the factory function.\n\t * You can either return a \"Directive Definition Object\" (see below) that defines the directive properties,\n\t * or just the `postLink` function (all other properties will have the default values).\n\t *\n\t *
\n\t * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n\t *
\n\t *\n\t * Here's an example directive declared with a Directive Definition Object:\n\t *\n\t * ```js\n\t * var myModule = angular.module(...);\n\t *\n\t * myModule.directive('directiveName', function factory(injectables) {\n\t * var directiveDefinitionObject = {\n\t * priority: 0,\n\t * template: '
', // or // function(tElement, tAttrs) { ... },\n\t * // or\n\t * // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },\n\t * transclude: false,\n\t * restrict: 'A',\n\t * templateNamespace: 'html',\n\t * scope: false,\n\t * controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n\t * controllerAs: 'stringIdentifier',\n\t * bindToController: false,\n\t * require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n\t * compile: function compile(tElement, tAttrs, transclude) {\n\t * return {\n\t * pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n\t * post: function postLink(scope, iElement, iAttrs, controller) { ... }\n\t * }\n\t * // or\n\t * // return function postLink( ... ) { ... }\n\t * },\n\t * // or\n\t * // link: {\n\t * // pre: function preLink(scope, iElement, iAttrs, controller) { ... },\n\t * // post: function postLink(scope, iElement, iAttrs, controller) { ... }\n\t * // }\n\t * // or\n\t * // link: function postLink( ... ) { ... }\n\t * };\n\t * return directiveDefinitionObject;\n\t * });\n\t * ```\n\t *\n\t *
\n\t * **Note:** Any unspecified options will use the default value. You can see the default values below.\n\t *
\n\t *\n\t * Therefore the above can be simplified as:\n\t *\n\t * ```js\n\t * var myModule = angular.module(...);\n\t *\n\t * myModule.directive('directiveName', function factory(injectables) {\n\t * var directiveDefinitionObject = {\n\t * link: function postLink(scope, iElement, iAttrs) { ... }\n\t * };\n\t * return directiveDefinitionObject;\n\t * // or\n\t * // return function postLink(scope, iElement, iAttrs) { ... }\n\t * });\n\t * ```\n\t *\n\t *\n\t *\n\t * ### Directive Definition Object\n\t *\n\t * The directive definition object provides instructions to the {@link ng.$compile\n\t * compiler}. The attributes are:\n\t *\n\t * #### `multiElement`\n\t * When this property is set to true, the HTML compiler will collect DOM nodes between\n\t * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n\t * together as the directive elements. It is recommended that this feature be used on directives\n\t * which are not strictly behavioural (such as {@link ngClick}), and which\n\t * do not manipulate or replace child nodes (such as {@link ngInclude}).\n\t *\n\t * #### `priority`\n\t * When there are multiple directives defined on a single DOM element, sometimes it\n\t * is necessary to specify the order in which the directives are applied. The `priority` is used\n\t * to sort the directives before their `compile` functions get called. Priority is defined as a\n\t * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n\t * are also run in priority order, but post-link functions are run in reverse order. The order\n\t * of directives with the same priority is undefined. The default priority is `0`.\n\t *\n\t * #### `terminal`\n\t * If set to true then the current `priority` will be the last set of directives\n\t * which will execute (any directives at the current priority will still execute\n\t * as the order of execution on same `priority` is undefined). Note that expressions\n\t * and other directives used in the directive's template will also be excluded from execution.\n\t *\n\t * #### `scope`\n\t * The scope property can be `true`, an object or a falsy value:\n\t *\n\t * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.\n\t *\n\t * * **`true`:** A new child scope that prototypically inherits from its parent will be created for\n\t * the directive's element. If multiple directives on the same element request a new scope,\n\t * only one new scope is created. The new scope rule does not apply for the root of the template\n\t * since the root of the template always gets a new scope.\n\t *\n\t * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's element. The\n\t * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent\n\t * scope. This is useful when creating reusable components, which should not accidentally read or modify\n\t * data in the parent scope.\n\t *\n\t * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the\n\t * directive's element. These local properties are useful for aliasing values for templates. The keys in\n\t * the object hash map to the name of the property on the isolate scope; the values define how the property\n\t * is bound to the parent scope, via matching attributes on the directive's element:\n\t *\n\t * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n\t * always a string since DOM attributes are strings. If no `attr` name is specified then the\n\t * attribute name is assumed to be the same as the local name.\n\t * Given `` and widget definition\n\t * of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect\n\t * the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the\n\t * `localName` property on the widget scope. The `name` is read from the parent scope (not\n\t * component scope).\n\t *\n\t * * `=` or `=attr` - set up bi-directional binding between a local scope property and the\n\t * parent scope property of name defined via the value of the `attr` attribute. If no `attr`\n\t * name is specified then the attribute name is assumed to be the same as the local name.\n\t * Given `` and widget definition of\n\t * `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the\n\t * value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected\n\t * in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent\n\t * scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You\n\t * can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If\n\t * you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use\n\t * `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional).\n\t *\n\t * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.\n\t * If no `attr` name is specified then the attribute name is assumed to be the same as the\n\t * local name. Given `` and widget definition of\n\t * `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to\n\t * a function wrapper for the `count = count + value` expression. Often it's desirable to\n\t * pass data from the isolated scope via an expression to the parent scope, this can be\n\t * done by passing a map of local variable names and values into the expression wrapper fn.\n\t * For example, if the expression is `increment(amount)` then we can specify the amount value\n\t * by calling the `localFn` as `localFn({amount: 22})`.\n\t *\n\t * In general it's possible to apply more than one directive to one element, but there might be limitations\n\t * depending on the type of scope required by the directives. The following points will help explain these limitations.\n\t * For simplicity only two directives are taken into account, but it is also applicable for several directives:\n\t *\n\t * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope\n\t * * **child scope** + **no scope** => Both directives will share one single child scope\n\t * * **child scope** + **child scope** => Both directives will share one single child scope\n\t * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use\n\t * its parent's scope\n\t * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot\n\t * be applied to the same element.\n\t * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives\n\t * cannot be applied to the same element.\n\t *\n\t *\n\t * #### `bindToController`\n\t * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will\n\t * allow a component to have its properties bound to the controller, rather than to scope. When the controller\n\t * is instantiated, the initial values of the isolate scope bindings are already available.\n\t *\n\t * #### `controller`\n\t * Controller constructor function. The controller is instantiated before the\n\t * pre-linking phase and can be accessed by other directives (see\n\t * `require` attribute). This allows the directives to communicate with each other and augment\n\t * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n\t *\n\t * * `$scope` - Current scope associated with the element\n\t * * `$element` - Current element\n\t * * `$attrs` - Current attributes object for the element\n\t * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n\t * `function([scope], cloneLinkingFn, futureParentElement)`.\n\t * * `scope`: optional argument to override the scope.\n\t * * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.\n\t * * `futureParentElement`:\n\t * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n\t * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n\t * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n\t * and when the `cloneLinkinFn` is passed,\n\t * as those elements need to created and cloned in a special way when they are defined outside their\n\t * usual containers (e.g. like ``).\n\t * * See also the `directive.templateNamespace` property.\n\t *\n\t *\n\t * #### `require`\n\t * Require another directive and inject its controller as the fourth argument to the linking function. The\n\t * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the\n\t * injected argument will be an array in corresponding order. If no such directive can be\n\t * found, or if the directive does not have a controller, then an error is raised (unless no link function\n\t * is specified, in which case error checking is skipped). The name can be prefixed with:\n\t *\n\t * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.\n\t * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.\n\t * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.\n\t * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.\n\t * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass\n\t * `null` to the `link` fn if not found.\n\t * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass\n\t * `null` to the `link` fn if not found.\n\t *\n\t *\n\t * #### `controllerAs`\n\t * Identifier name for a reference to the controller in the directive's scope.\n\t * This allows the controller to be referenced from the directive template. This is especially\n\t * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible\n\t * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the\n\t * `controllerAs` reference might overwrite a property that already exists on the parent scope.\n\t *\n\t *\n\t * #### `restrict`\n\t * String of subset of `EACM` which restricts the directive to a specific directive\n\t * declaration style. If omitted, the defaults (elements and attributes) are used.\n\t *\n\t * * `E` - Element name (default): ``\n\t * * `A` - Attribute (default): `
`\n\t * * `C` - Class: `
`\n\t * * `M` - Comment: ``\n\t *\n\t *\n\t * #### `templateNamespace`\n\t * String representing the document type used by the markup in the template.\n\t * AngularJS needs this information as those elements need to be created and cloned\n\t * in a special way when they are defined outside their usual containers like `` and ``.\n\t *\n\t * * `html` - All root nodes in the template are HTML. Root nodes may also be\n\t * top-level elements such as `` or ``.\n\t * * `svg` - The root nodes in the template are SVG elements (excluding ``).\n\t * * `math` - The root nodes in the template are MathML elements (excluding ``).\n\t *\n\t * If no `templateNamespace` is specified, then the namespace is considered to be `html`.\n\t *\n\t * #### `template`\n\t * HTML markup that may:\n\t * * Replace the contents of the directive's element (default).\n\t * * Replace the directive's element itself (if `replace` is true - DEPRECATED).\n\t * * Wrap the contents of the directive's element (if `transclude` is true).\n\t *\n\t * Value may be:\n\t *\n\t * * A string. For example `
{{delete_str}}
`.\n\t * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n\t * function api below) and returns a string value.\n\t *\n\t *\n\t * #### `templateUrl`\n\t * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n\t *\n\t * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n\t * for later when the template has been resolved. In the meantime it will continue to compile and link\n\t * sibling and parent elements as though this element had not contained any directives.\n\t *\n\t * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n\t * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n\t * case when only one deeply nested directive has `templateUrl`.\n\t *\n\t * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}\n\t *\n\t * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n\t * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n\t * a string value representing the url. In either case, the template URL is passed through {@link\n\t * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n\t *\n\t *\n\t * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)\n\t * specify what the template should replace. Defaults to `false`.\n\t *\n\t * * `true` - the template will replace the directive's element.\n\t * * `false` - the template will replace the contents of the directive's element.\n\t *\n\t * The replacement process migrates all of the attributes / classes from the old element to the new\n\t * one. See the {@link guide/directive#template-expanding-directive\n\t * Directives Guide} for an example.\n\t *\n\t * There are very few scenarios where element replacement is required for the application function,\n\t * the main one being reusable custom components that are used within SVG contexts\n\t * (because SVG doesn't work with custom elements in the DOM tree).\n\t *\n\t * #### `transclude`\n\t * Extract the contents of the element where the directive appears and make it available to the directive.\n\t * The contents are compiled and provided to the directive as a **transclusion function**. See the\n\t * {@link $compile#transclusion Transclusion} section below.\n\t *\n\t * There are two kinds of transclusion depending upon whether you want to transclude just the contents of the\n\t * directive's element or the entire element:\n\t *\n\t * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n\t * * `'element'` - transclude the whole of the directive's element including any directives on this\n\t * element that defined at a lower priority than this directive. When used, the `template`\n\t * property is ignored.\n\t *\n\t *\n\t * #### `compile`\n\t *\n\t * ```js\n\t * function compile(tElement, tAttrs, transclude) { ... }\n\t * ```\n\t *\n\t * The compile function deals with transforming the template DOM. Since most directives do not do\n\t * template transformation, it is not used often. The compile function takes the following arguments:\n\t *\n\t * * `tElement` - template element - The element where the directive has been declared. It is\n\t * safe to do template transformation on the element and child elements only.\n\t *\n\t * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n\t * between all directive compile functions.\n\t *\n\t * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n\t *\n\t *
\n\t * **Note:** The template instance and the link instance may be different objects if the template has\n\t * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n\t * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n\t * should be done in a linking function rather than in a compile function.\n\t *
\n\n\t *
\n\t * **Note:** The compile function cannot handle directives that recursively use themselves in their\n\t * own templates or compile functions. Compiling these directives results in an infinite loop and a\n\t * stack overflow errors.\n\t *\n\t * This can be avoided by manually using $compile in the postLink function to imperatively compile\n\t * a directive's template instead of relying on automatic template compilation via `template` or\n\t * `templateUrl` declaration or manual compilation inside the compile function.\n\t *
\n\t *\n\t *
\n\t * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n\t * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n\t * to the link function instead.\n\t *
\n\n\t * A compile function can have a return value which can be either a function or an object.\n\t *\n\t * * returning a (post-link) function - is equivalent to registering the linking function via the\n\t * `link` property of the config object when the compile function is empty.\n\t *\n\t * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n\t * control when a linking function should be called during the linking phase. See info about\n\t * pre-linking and post-linking functions below.\n\t *\n\t *\n\t * #### `link`\n\t * This property is used only if the `compile` property is not defined.\n\t *\n\t * ```js\n\t * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n\t * ```\n\t *\n\t * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n\t * executed after the template has been cloned. This is where most of the directive logic will be\n\t * put.\n\t *\n\t * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n\t * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n\t *\n\t * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n\t * manipulate the children of the element only in `postLink` function since the children have\n\t * already been linked.\n\t *\n\t * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n\t * between all directive linking functions.\n\t *\n\t * * `controller` - the directive's required controller instance(s) - Instances are shared\n\t * among all directives, which allows the directives to use the controllers as a communication\n\t * channel. The exact value depends on the directive's `require` property:\n\t * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one\n\t * * `string`: the controller instance\n\t * * `array`: array of controller instances\n\t *\n\t * If a required controller cannot be found, and it is optional, the instance is `null`,\n\t * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.\n\t *\n\t * Note that you can also require the directive's own controller - it will be made available like\n\t * any other controller.\n\t *\n\t * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n\t * This is the same as the `$transclude`\n\t * parameter of directive controllers, see there for details.\n\t * `function([scope], cloneLinkingFn, futureParentElement)`.\n\t *\n\t * #### Pre-linking function\n\t *\n\t * Executed before the child elements are linked. Not safe to do DOM transformation since the\n\t * compiler linking function will fail to locate the correct elements for linking.\n\t *\n\t * #### Post-linking function\n\t *\n\t * Executed after the child elements are linked.\n\t *\n\t * Note that child elements that contain `templateUrl` directives will not have been compiled\n\t * and linked since they are waiting for their template to load asynchronously and their own\n\t * compilation and linking has been suspended until that occurs.\n\t *\n\t * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n\t * for their async templates to be resolved.\n\t *\n\t *\n\t * ### Transclusion\n\t *\n\t * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and\n\t * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n\t * scope from where they were taken.\n\t *\n\t * Transclusion is used (often with {@link ngTransclude}) to insert the\n\t * original contents of a directive's element into a specified place in the template of the directive.\n\t * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n\t * content has access to the properties on the scope from which it was taken, even if the directive\n\t * has isolated scope.\n\t * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n\t *\n\t * This makes it possible for the widget to have private state for its template, while the transcluded\n\t * content has access to its originating scope.\n\t *\n\t *
\n\t * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n\t * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n\t * Testing Transclusion Directives}.\n\t *
\n\t *\n\t * #### Transclusion Functions\n\t *\n\t * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n\t * function** to the directive's `link` function and `controller`. This transclusion function is a special\n\t * **linking function** that will return the compiled contents linked to a new transclusion scope.\n\t *\n\t *
\n\t * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n\t * ngTransclude will deal with it for us.\n\t *
\n\t *\n\t * If you want to manually control the insertion and removal of the transcluded content in your directive\n\t * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery\n\t * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n\t *\n\t * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n\t * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n\t * content and the `scope` is the newly created transclusion scope, to which the clone is bound.\n\t *\n\t *
\n\t * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function\n\t * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n\t *
\n\t *\n\t * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n\t * attach function**:\n\t *\n\t * ```js\n\t * var transcludedContent, transclusionScope;\n\t *\n\t * $transclude(function(clone, scope) {\n\t * element.append(clone);\n\t * transcludedContent = clone;\n\t * transclusionScope = scope;\n\t * });\n\t * ```\n\t *\n\t * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n\t * associated transclusion scope:\n\t *\n\t * ```js\n\t * transcludedContent.remove();\n\t * transclusionScope.$destroy();\n\t * ```\n\t *\n\t *
\n\t * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n\t * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),\n\t * then you are also responsible for calling `$destroy` on the transclusion scope.\n\t *
\n\t *\n\t * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n\t * automatically destroy their transluded clones as necessary so you do not need to worry about this if\n\t * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n\t *\n\t *\n\t * #### Transclusion Scopes\n\t *\n\t * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n\t * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n\t * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n\t * was taken.\n\t *\n\t * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n\t * like this:\n\t *\n\t * ```html\n\t *
\n\t *
\n\t *
\n\t *
\n\t *
\n\t *
\n\t * ```\n\t *\n\t * The `$parent` scope hierarchy will look like this:\n\t *\n\t * ```\n\t * - $rootScope\n\t * - isolate\n\t * - transclusion\n\t * ```\n\t *\n\t * but the scopes will inherit prototypically from different scopes to their `$parent`.\n\t *\n\t * ```\n\t * - $rootScope\n\t * - transclusion\n\t * - isolate\n\t * ```\n\t *\n\t *\n\t * ### Attributes\n\t *\n\t * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n\t * `link()` or `compile()` functions. It has a variety of uses.\n\t *\n\t * accessing *Normalized attribute names:*\n\t * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.\n\t * the attributes object allows for normalized access to\n\t * the attributes.\n\t *\n\t * * *Directive inter-communication:* All directives share the same instance of the attributes\n\t * object which allows the directives to use the attributes object as inter directive\n\t * communication.\n\t *\n\t * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n\t * allowing other directives to read the interpolated value.\n\t *\n\t * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n\t * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n\t * the only way to easily get the actual value because during the linking phase the interpolation\n\t * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n\t *\n\t * ```js\n\t * function linkingFn(scope, elm, attrs, ctrl) {\n\t * // get the attribute value\n\t * console.log(attrs.ngModel);\n\t *\n\t * // change the attribute\n\t * attrs.$set('ngModel', 'new value');\n\t *\n\t * // observe changes to interpolated attribute\n\t * attrs.$observe('ngModel', function(value) {\n\t * console.log('ngModel has changed value to ' + value);\n\t * });\n\t * }\n\t * ```\n\t *\n\t * ## Example\n\t *\n\t *
\n\t * **Note**: Typically directives are registered with `module.directive`. The example below is\n\t * to illustrate how `$compile` works.\n\t *
\n\t *\n\t \n\t \n\t \n\t

\n\t * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it\n\t * e.g. will not use the right outer scope. Please pass the transclude function as a\n\t * `parentBoundTranscludeFn` to the link function instead.\n\t *
\n\t *\n\t * @param {number} maxPriority only apply directives lower than given priority (Only effects the\n\t * root element(s), not their children)\n\t * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template\n\t * (a DOM element/tree) to a scope. Where:\n\t *\n\t * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n\t * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n\t * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n\t * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n\t * called as:
`cloneAttachFn(clonedElement, scope)` where:\n\t *\n\t * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n\t * * `scope` - is the current scope with which the linking function is working with.\n\t *\n\t * * `options` - An optional object hash with linking options. If `options` is provided, then the following\n\t * keys may be used to control linking behavior:\n\t *\n\t * * `parentBoundTranscludeFn` - the transclude function made available to\n\t * directives; if given, it will be passed through to the link functions of\n\t * directives found in `element` during compilation.\n\t * * `transcludeControllers` - an object hash with keys that map controller names\n\t * to controller instances; if given, it will make the controllers\n\t * available to directives.\n\t * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n\t * the cloned elements; only needed for transcludes that are allowed to contain non html\n\t * elements (e.g. SVG elements). See also the directive.controller property.\n\t *\n\t * Calling the linking function returns the element of the template. It is either the original\n\t * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n\t *\n\t * After linking the view is not updated until after a call to $digest which typically is done by\n\t * Angular automatically.\n\t *\n\t * If you need access to the bound view, there are two ways to do it:\n\t *\n\t * - If you are not asking the linking function to clone the template, create the DOM element(s)\n\t * before you send them to the compiler and keep this reference around.\n\t * ```js\n\t * var element = $compile('

{{total}}

')(scope);\n\t * ```\n\t *\n\t * - if on the other hand, you need the element to be cloned, the view reference from the original\n\t * example would not point to the clone, but rather to the original template that was cloned.

While for simple usage patterns this doesn't matter much, for advanced usage\n\t * it is important to familiarize yourself with these APIs and the guarantees they provide.\n\t *\n\t *\n\t * ## General usage\n\t * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —\n\t * that is used to generate an HTTP request and returns a {@link ng.$q promise}.\n\t *\n\t * ```js\n\t * // Simple GET request example:\n\t * $http({\n\t * method: 'GET',\n\t * url: '/someUrl'\n\t * }).then(function successCallback(response) {\n\t * // this callback will be called asynchronously\n\t * // when the response is available\n\t * }, function errorCallback(response) {\n\t * // called asynchronously if an error occurs\n\t * // or server returns response with an error status.\n\t * });\n\t * ```\n\t *\n\t * The response object has these properties:\n\t *\n\t * - **data** – `{string|Object}` – The response body transformed with the transform\n\t * functions.\n\t * - **status** – `{number}` – HTTP status code of the response.\n\t * - **headers** – `{function([headerName])}` – Header getter function.\n\t * - **config** – `{Object}` – The configuration object that was used to generate the request.\n\t * - **statusText** – `{string}` – HTTP status text of the response.\n\t *\n\t * A response status code between 200 and 299 is considered a success status and\n\t * will result in the success callback being called. Note that if the response is a redirect,\n\t * XMLHttpRequest will transparently follow it, meaning that the error callback will not be\n\t * called for such responses.\n\t *\n\t *\n\t * ## Shortcut methods\n\t *\n\t * Shortcut methods are also available. All shortcut methods require passing in the URL, and\n\t * request data must be passed in for POST/PUT requests. An optional config can be passed as the\n\t * last argument.\n\t *\n\t * ```js\n\t * $http.get('/someUrl', config).then(successCallback, errorCallback);\n\t * $http.post('/someUrl', data, config).then(successCallback, errorCallback);\n\t * ```\n\t *\n\t * Complete list of shortcut methods:\n\t *\n\t * - {@link ng.$http#get $http.get}\n\t * - {@link ng.$http#head $http.head}\n\t * - {@link ng.$http#post $http.post}\n\t * - {@link ng.$http#put $http.put}\n\t * - {@link ng.$http#delete $http.delete}\n\t * - {@link ng.$http#jsonp $http.jsonp}\n\t * - {@link ng.$http#patch $http.patch}\n\t *\n\t *\n\t * ## Writing Unit Tests that use $http\n\t * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n\t * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n\t * request using trained responses.\n\t *\n\t * ```\n\t * $httpBackend.expectGET(...);\n\t * $http.get(...);\n\t * $httpBackend.flush();\n\t * ```\n\t *\n\t * ## Deprecation Notice\n\t *
\n\t * The `$http` legacy promise methods `success` and `error` have been deprecated.\n\t * Use the standard `then` method instead.\n\t * If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to\n\t * `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.\n\t *
\n\t *\n\t * ## Setting HTTP Headers\n\t *\n\t * The $http service will automatically add certain HTTP headers to all requests. These defaults\n\t * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n\t * object, which currently contains this default configuration:\n\t *\n\t * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n\t * - `Accept: application/json, text/plain, * / *`\n\t * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n\t * - `Content-Type: application/json`\n\t * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n\t * - `Content-Type: application/json`\n\t *\n\t * To add or overwrite these defaults, simply add or remove a property from these configuration\n\t * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n\t * with the lowercased HTTP method name as the key, e.g.\n\t * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.\n\t *\n\t * The defaults can also be set at runtime via the `$http.defaults` object in the same\n\t * fashion. For example:\n\t *\n\t * ```\n\t * module.run(function($http) {\n\t * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'\n\t * });\n\t * ```\n\t *\n\t * In addition, you can supply a `headers` property in the config object passed when\n\t * calling `$http(config)`, which overrides the defaults without changing them globally.\n\t *\n\t * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n\t * Use the `headers` property, setting the desired header to `undefined`. For example:\n\t *\n\t * ```js\n\t * var req = {\n\t * method: 'POST',\n\t * url: 'http://example.com',\n\t * headers: {\n\t * 'Content-Type': undefined\n\t * },\n\t * data: { test: 'test' }\n\t * }\n\t *\n\t * $http(req).then(function(){...}, function(){...});\n\t * ```\n\t *\n\t * ## Transforming Requests and Responses\n\t *\n\t * Both requests and responses can be transformed using transformation functions: `transformRequest`\n\t * and `transformResponse`. These properties can be a single function that returns\n\t * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n\t * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n\t *\n\t * ### Default Transformations\n\t *\n\t * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n\t * `defaults.transformResponse` properties. If a request does not provide its own transformations\n\t * then these will be applied.\n\t *\n\t * You can augment or replace the default transformations by modifying these properties by adding to or\n\t * replacing the array.\n\t *\n\t * Angular provides the following default transformations:\n\t *\n\t * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):\n\t *\n\t * - If the `data` property of the request configuration object contains an object, serialize it\n\t * into JSON format.\n\t *\n\t * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):\n\t *\n\t * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n\t * - If JSON response is detected, deserialize it using a JSON parser.\n\t *\n\t *\n\t * ### Overriding the Default Transformations Per Request\n\t *\n\t * If you wish override the request/response transformations only for a single request then provide\n\t * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n\t * into `$http`.\n\t *\n\t * Note that if you provide these properties on the config object the default transformations will be\n\t * overwritten. If you wish to augment the default transformations then you must include them in your\n\t * local transformation array.\n\t *\n\t * The following code demonstrates adding a new response transformation to be run after the default response\n\t * transformations have been run.\n\t *\n\t * ```js\n\t * function appendTransform(defaults, transform) {\n\t *\n\t * // We can't guarantee that the default transformation is an array\n\t * defaults = angular.isArray(defaults) ? defaults : [defaults];\n\t *\n\t * // Append the new transformation to the defaults\n\t * return defaults.concat(transform);\n\t * }\n\t *\n\t * $http({\n\t * url: '...',\n\t * method: 'GET',\n\t * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n\t * return doTransform(value);\n\t * })\n\t * });\n\t * ```\n\t *\n\t *\n\t * ## Caching\n\t *\n\t * To enable caching, set the request configuration `cache` property to `true` (to use default\n\t * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).\n\t * When the cache is enabled, `$http` stores the response from the server in the specified\n\t * cache. The next time the same request is made, the response is served from the cache without\n\t * sending a request to the server.\n\t *\n\t * Note that even if the response is served from cache, delivery of the data is asynchronous in\n\t * the same way that real requests are.\n\t *\n\t * If there are multiple GET requests for the same URL that should be cached using the same\n\t * cache, but the cache is not populated yet, only one request to the server will be made and\n\t * the remaining requests will be fulfilled using the response from the first request.\n\t *\n\t * You can change the default cache to a new object (built with\n\t * {@link ng.$cacheFactory `$cacheFactory`}) by updating the\n\t * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set\n\t * their `cache` property to `true` will now use this cache object.\n\t *\n\t * If you set the default cache to `false` then only requests that specify their own custom\n\t * cache object will be cached.\n\t *\n\t * ## Interceptors\n\t *\n\t * Before you start creating interceptors, be sure to understand the\n\t * {@link ng.$q $q and deferred/promise APIs}.\n\t *\n\t * For purposes of global error handling, authentication, or any kind of synchronous or\n\t * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n\t * able to intercept requests before they are handed to the server and\n\t * responses before they are handed over to the application code that\n\t * initiated these requests. The interceptors leverage the {@link ng.$q\n\t * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n\t *\n\t * The interceptors are service factories that are registered with the `$httpProvider` by\n\t * adding them to the `$httpProvider.interceptors` array. The factory is called and\n\t * injected with dependencies (if specified) and returns the interceptor.\n\t *\n\t * There are two kinds of interceptors (and two kinds of rejection interceptors):\n\t *\n\t * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to\n\t * modify the `config` object or create a new one. The function needs to return the `config`\n\t * object directly, or a promise containing the `config` or a new `config` object.\n\t * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n\t * resolved with a rejection.\n\t * * `response`: interceptors get called with http `response` object. The function is free to\n\t * modify the `response` object or create a new one. The function needs to return the `response`\n\t * object directly, or as a promise containing the `response` or a new `response` object.\n\t * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n\t * resolved with a rejection.\n\t *\n\t *\n\t * ```js\n\t * // register the interceptor as a service\n\t * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n\t * return {\n\t * // optional method\n\t * 'request': function(config) {\n\t * // do something on success\n\t * return config;\n\t * },\n\t *\n\t * // optional method\n\t * 'requestError': function(rejection) {\n\t * // do something on error\n\t * if (canRecover(rejection)) {\n\t * return responseOrNewPromise\n\t * }\n\t * return $q.reject(rejection);\n\t * },\n\t *\n\t *\n\t *\n\t * // optional method\n\t * 'response': function(response) {\n\t * // do something on success\n\t * return response;\n\t * },\n\t *\n\t * // optional method\n\t * 'responseError': function(rejection) {\n\t * // do something on error\n\t * if (canRecover(rejection)) {\n\t * return responseOrNewPromise\n\t * }\n\t * return $q.reject(rejection);\n\t * }\n\t * };\n\t * });\n\t *\n\t * $httpProvider.interceptors.push('myHttpInterceptor');\n\t *\n\t *\n\t * // alternatively, register the interceptor via an anonymous factory\n\t * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n\t * return {\n\t * 'request': function(config) {\n\t * // same as above\n\t * },\n\t *\n\t * 'response': function(response) {\n\t * // same as above\n\t * }\n\t * };\n\t * });\n\t * ```\n\t *\n\t * ## Security Considerations\n\t *\n\t * When designing web applications, consider security threats from:\n\t *\n\t * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n\t * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n\t *\n\t * Both server and the client must cooperate in order to eliminate these threats. Angular comes\n\t * pre-configured with strategies that address these issues, but for this to work backend server\n\t * cooperation is required.\n\t *\n\t * ### JSON Vulnerability Protection\n\t *\n\t * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n\t * allows third party website to turn your JSON resource URL into\n\t * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n\t * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n\t * Angular will automatically strip the prefix before processing it as JSON.\n\t *\n\t * For example if your server needs to return:\n\t * ```js\n\t * ['one','two']\n\t * ```\n\t *\n\t * which is vulnerable to attack, your server can return:\n\t * ```js\n\t * )]}',\n\t * ['one','two']\n\t * ```\n\t *\n\t * Angular will strip the prefix, before processing the JSON.\n\t *\n\t *\n\t * ### Cross Site Request Forgery (XSRF) Protection\n\t *\n\t * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which\n\t * an unauthorized site can gain your user's private data. Angular provides a mechanism\n\t * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie\n\t * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only\n\t * JavaScript that runs on your domain could read the cookie, your server can be assured that\n\t * the XHR came from JavaScript running on your domain. The header will not be set for\n\t * cross-domain requests.\n\t *\n\t * To take advantage of this, your server needs to set a token in a JavaScript readable session\n\t * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n\t * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure\n\t * that only JavaScript running on your domain could have sent the request. The token must be\n\t * unique for each user and must be verifiable by the server (to prevent the JavaScript from\n\t * making up its own tokens). We recommend that the token is a digest of your site's\n\t * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n\t * for added security.\n\t *\n\t * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName\n\t * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,\n\t * or the per-request config object.\n\t *\n\t * In order to prevent collisions in environments where multiple Angular apps share the\n\t * same domain or subdomain, we recommend that each application uses unique cookie name.\n\t *\n\t * @param {object} config Object describing the request to be made and how it should be\n\t * processed. The object has following properties:\n\t *\n\t * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)\n\t * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.\n\t * - **params** – `{Object.}` – Map of strings or objects which will be serialized\n\t * with the `paramSerializer` and appended as GET parameters.\n\t * - **data** – `{string|Object}` – Data to be sent as the request message data.\n\t * - **headers** – `{Object}` – Map of strings or functions which return strings representing\n\t * HTTP headers to send to the server. If the return value of a function is null, the\n\t * header will not be sent. Functions accept a config object as an argument.\n\t * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.\n\t * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.\n\t * - **transformRequest** –\n\t * `{function(data, headersGetter)|Array.}` –\n\t * transform function or an array of such functions. The transform function takes the http\n\t * request body and headers and returns its transformed (typically serialized) version.\n\t * See {@link ng.$http#overriding-the-default-transformations-per-request\n\t * Overriding the Default Transformations}\n\t * - **transformResponse** –\n\t * `{function(data, headersGetter, status)|Array.}` –\n\t * transform function or an array of such functions. The transform function takes the http\n\t * response body, headers and status and returns its transformed (typically deserialized) version.\n\t * See {@link ng.$http#overriding-the-default-transformations-per-request\n\t * Overriding the Default TransformationjqLiks}\n\t * - **paramSerializer** - `{string|function(Object):string}` - A function used to\n\t * prepare the string representation of request parameters (specified as an object).\n\t * If specified as string, it is interpreted as function registered with the\n\t * {@link $injector $injector}, which means you can create your own serializer\n\t * by registering it as a {@link auto.$provide#service service}.\n\t * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};\n\t * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}\n\t * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the\n\t * GET request, otherwise if a cache instance built with\n\t * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for\n\t * caching.\n\t * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}\n\t * that should abort the request when resolved.\n\t * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the\n\t * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)\n\t * for more information.\n\t * - **responseType** - `{string}` - see\n\t * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).\n\t *\n\t * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object\n\t * when the request succeeds or fails.\n\t *\n\t *\n\t * @property {Array.} pendingRequests Array of config objects for currently pending\n\t * requests. This is primarily meant to be used for debugging purposes.\n\t *\n\t *\n\t * @example\n\t\n\t\n\t

So, for HTML elements interpolated\n\t * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter\n\t * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,\n\t * this is typically useful only when user-data is used in rendering a template from the server, or\n\t * when otherwise untrusted data is used by a directive.\n\t *\n\t * \n\t * \n\t *

their return values (or exceptions)\n\t * when they are done processing.\n\t *\n\t * This is an implementation of promises/deferred objects inspired by\n\t * [Kris Kowal's Q](https://github.com/kriskowal/q).\n\t *\n\t * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred\n\t * implementations, and the other which resembles ES6 promises to some degree.\n\t *\n\t * # $q constructor\n\t *\n\t * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`\n\t * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,\n\t * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).\n\t *\n\t * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are\n\t * available yet.\n\t *\n\t * It can be used like so:\n\t *\n\t * ```js\n\t * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n\t * // are available in the current lexical scope (they could have been injected or passed in).\n\t *\n\t * function asyncGreet(name) {\n\t * // perform some asynchronous operation, resolve or reject the promise when appropriate.\n\t * return $q(function(resolve, reject) {\n\t * setTimeout(function() {\n\t * if (okToGreet(name)) {\n\t * resolve('Hello, ' + name + '!');\n\t * } else {\n\t * reject('Greeting ' + name + ' is not allowed.');\n\t * }\n\t * }, 1000);\n\t * });\n\t * }\n\t *\n\t * var promise = asyncGreet('Robin Hood');\n\t * promise.then(function(greeting) {\n\t * alert('Success: ' + greeting);\n\t * }, function(reason) {\n\t * alert('Failed: ' + reason);\n\t * });\n\t * ```\n\t *\n\t * Note: progress/notify callbacks are not currently supported via the ES6-style interface.\n\t *\n\t * Note: unlike ES6 behaviour, an exception thrown in the constructor function will NOT implicitly reject the promise.\n\t *\n\t * However, the more traditional CommonJS-style usage is still available, and documented below.\n\t *\n\t * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an\n\t * interface for interacting with an object that represents the result of an action that is\n\t * performed asynchronously, and may or may not be finished at any given point in time.\n\t *\n\t * From the perspective of dealing with error handling, deferred and promise APIs are to\n\t * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.\n\t *\n\t * ```js\n\t * // for the purpose of this example let's assume that variables `$q` and `okToGreet`\n\t * // are available in the current lexical scope (they could have been injected or passed in).\n\t *\n\t * function asyncGreet(name) {\n\t * var deferred = $q.defer();\n\t *\n\t * setTimeout(function() {\n\t * deferred.notify('About to greet ' + name + '.');\n\t *\n\t * if (okToGreet(name)) {\n\t * deferred.resolve('Hello, ' + name + '!');\n\t * } else {\n\t * deferred.reject('Greeting ' + name + ' is not allowed.');\n\t * }\n\t * }, 1000);\n\t *\n\t * return deferred.promise;\n\t * }\n\t *\n\t * var promise = asyncGreet('Robin Hood');\n\t * promise.then(function(greeting) {\n\t * alert('Success: ' + greeting);\n\t * }, function(reason) {\n\t * alert('Failed: ' + reason);\n\t * }, function(update) {\n\t * alert('Got notification: ' + update);\n\t * });\n\t * ```\n\t *\n\t * At first it might not be obvious why this extra complexity is worth the trouble. The payoff\n\t * comes in the way of guarantees that promise and deferred APIs make, see\n\t * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.\n\t *\n\t * Additionally the promise api allows for composition that is very hard to do with the\n\t * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.\n\t * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the\n\t * section on serial or parallel joining of promises.\n\t *\n\t * # The Deferred API\n\t *\n\t * A new instance of deferred is constructed by calling `$q.defer()`.\n\t *\n\t * The purpose of the deferred object is to expose the associated Promise instance as well as APIs\n\t * that can be used for signaling the successful or unsuccessful completion, as well as the status\n\t * of the task.\n\t *\n\t * **Methods**\n\t *\n\t * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection\n\t * constructed via `$q.reject`, the promise will be rejected instead.\n\t * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to\n\t * resolving it with a rejection constructed via `$q.reject`.\n\t * - `notify(value)` - provides updates on the status of the promise's execution. This may be called\n\t * multiple times before the promise is either resolved or rejected.\n\t *\n\t * **Properties**\n\t *\n\t * - promise – `{Promise}` – promise object associated with this deferred.\n\t *\n\t *\n\t * # The Promise API\n\t *\n\t * A new promise instance is created when a deferred instance is created and can be retrieved by\n\t * calling `deferred.promise`.\n\t *\n\t * The purpose of the promise object is to allow for interested parties to get access to the result\n\t * of the deferred task when it completes.\n\t *\n\t * **Methods**\n\t *\n\t * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or\n\t * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously\n\t * as soon as the result is available. The callbacks are called with a single argument: the result\n\t * or rejection reason. Additionally, the notify callback may be called zero or more times to\n\t * provide a progress indication, before the promise is resolved or rejected.\n\t *\n\t * This method *returns a new promise* which is resolved or rejected via the return value of the\n\t * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved\n\t * with the value which is resolved in that promise using\n\t * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).\n\t * It also notifies via the return value of the `notifyCallback` method. The promise cannot be\n\t * resolved or rejected from the notifyCallback method.\n\t *\n\t * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`\n\t *\n\t * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,\n\t * but to do so without modifying the final value. This is useful to release resources or do some\n\t * clean-up that needs to be done whether the promise was rejected or resolved. See the [full\n\t * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for\n\t * more information.\n\t *\n\t * # Chaining promises\n\t *\n\t * Because calling the `then` method of a promise returns a new derived promise, it is easily\n\t * possible to create a chain of promises:\n\t *\n\t * ```js\n\t * promiseB = promiseA.then(function(result) {\n\t * return result + 1;\n\t * });\n\t *\n\t * // promiseB will be resolved immediately after promiseA is resolved and its value\n\t * // will be the result of promiseA incremented by 1\n\t * ```\n\t *\n\t * It is possible to create chains of any length and since a promise can be resolved with another\n\t * promise (which will defer its resolution further), it is possible to pause/defer resolution of\n\t * the promises at any point in the chain. This makes it possible to implement powerful APIs like\n\t * $http's response interceptors.\n\t *\n\t *\n\t * # Differences between Kris Kowal's Q and $q\n\t *\n\t * There are two main differences:\n\t *\n\t * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation\n\t * mechanism in angular, which means faster propagation of resolution or rejection into your\n\t * models and avoiding unnecessary browser repaints, which would result in flickering UI.\n\t * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains\n\t * all the important functionality needed for common async tasks.\n\t *\n\t * # Testing\n\t *\n\t * ```js\n\t * it('should simulate promise', inject(function($q, $rootScope) {\n\t * var deferred = $q.defer();\n\t * var promise = deferred.promise;\n\t * var resolvedValue;\n\t *\n\t * promise.then(function(value) { resolvedValue = value; });\n\t * expect(resolvedValue).toBeUndefined();\n\t *\n\t * // Simulate resolving of promise\n\t * deferred.resolve(123);\n\t * // Note that the 'then' function does not get called synchronously.\n\t * // This is because we want the promise API to always be async, whether or not\n\t * // it got called synchronously or asynchronously.\n\t * expect(resolvedValue).toBeUndefined();\n\t *\n\t * // Propagate promise resolution to 'then' functions using $apply().\n\t * $rootScope.$apply();\n\t * expect(resolvedValue).toEqual(123);\n\t * }));\n\t * ```\n\t *\n\t * @param {function(function, function)} resolver Function which is responsible for resolving or\n\t * rejecting the newly created promise.

(`watchExpression` should not change\n\t * its value when executed multiple times with the same input because it may be executed multiple\n\t * times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be\n\t * [idempotent](http://en.wikipedia.org/wiki/Idempotence).\n\t * - The `listener` is called only when the value from the current `watchExpression` and the\n\t * previous call to `watchExpression` are not equal (with the exception of the initial run,\n\t * see below). Inequality is determined according to reference inequality,\n\t * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)\n\t * via the `!==` Javascript operator, unless `objectEquality == true`\n\t * (see next point)\n\t * - When `objectEquality == true`, inequality of the `watchExpression` is determined\n\t * according to the {@link angular.equals} function. To save the value of the object for\n\t * later comparison, the {@link angular.copy} function is used. This therefore means that\n\t * watching complex objects will have adverse memory and performance implications.\n\t * - The watch `listener` may change the model, which may trigger other `listener`s to fire.\n\t * This is achieved by rerunning the watchers until no changes are detected. The rerun\n\t * iteration limit is 10 to prevent an infinite loop deadlock.\n\t *\n\t *\n\t * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,\n\t * you can register a `watchExpression` function with no `listener`. (Be prepared for\n\t * multiple calls to your `watchExpression` because it will execute multiple times in a\n\t * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)\n\t *\n\t * After a watcher is registered with the scope, the `listener` fn is called asynchronously\n\t * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the\n\t * watcher. In rare cases, this is undesirable because the listener is called when the result\n\t * of `watchExpression` didn't change.

One example of\n\t * such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer\n\t * to these contexts as privileged or SCE contexts.\n\t *\n\t * As of version 1.2, Angular ships with SCE enabled by default.\n\t *\n\t * Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow\n\t * one to execute arbitrary javascript by the use of the expression() syntax. Refer\n\t * to learn more about them.\n\t * You can ensure your document is in standards mode and not quirks mode by adding ``\n\t * to the top of your HTML document.\n\t *\n\t * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for\n\t * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.\n\t *\n\t * Here's an example of a binding in a privileged context:\n\t *\n\t * ```\n\t * \n\t *
\n\t * ```\n\t *\n\t * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE\n\t * disabled, this application allows the user to render arbitrary HTML into the DIV.\n\t * In a more realistic example, one may be rendering user comments, blog articles, etc. via\n\t * bindings. (HTML is just one example of a context where rendering user controlled input creates\n\t * security vulnerabilities.)\n\t *\n\t * For the case of HTML, you might use a library, either on the client side, or on the server side,\n\t * to sanitize unsafe HTML before binding to the value and rendering it in the document.\n\t *\n\t * How would you ensure that every place that used these types of bindings was bound to a value that\n\t * was sanitized by your library (or returned as safe for rendering by your server?) How can you\n\t * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some\n\t * properties/fields and forgot to update the binding to the sanitized value?\n\t *\n\t * To be secure by default, you want to ensure that any such bindings are disallowed unless you can\n\t * determine that something explicitly says it's safe to use a value for binding in that\n\t * context. You can then audit your code (a simple grep would do) to ensure that this is only done\n\t * for those values that you can easily tell are safe - because they were received from your server,\n\t * sanitized by your library, etc. You can organize your codebase to help with this - perhaps\n\t * allowing only the files in a specific directory to do this. Ensuring that the internal API\n\t * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.\n\t *\n\t * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}\n\t * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to\n\t * obtain values that will be accepted by SCE / privileged contexts.\n\t *\n\t *\n\t * ## How does it work?\n\t *\n\t * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted\n\t * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link\n\t * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the\n\t * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.\n\t *\n\t * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link\n\t * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly\n\t * simplified):\n\t *\n\t * ```\n\t * var ngBindHtmlDirective = ['$sce', function($sce) {\n\t * return function(scope, element, attr) {\n\t * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {\n\t * element.html(value || '');\n\t * });\n\t * };\n\t * }];\n\t * ```\n\t *\n\t * ## Impact on loading templates\n\t *\n\t * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as\n\t * `templateUrl`'s specified by {@link guide/directive directives}.\n\t *\n\t * By default, Angular only loads templates from the same domain and protocol as the application\n\t * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl\n\t * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or\n\t * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist\n\t * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.\n\t *\n\t * *Please note*:\n\t * The browser's\n\t * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)\n\t * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)\n\t * policy apply in addition to this and may further restrict whether the template is successfully\n\t * loaded. This means that without the right CORS policy, loading templates from a different domain\n\t * won't work on all browsers. Also, loading templates from `file://` URL does not work on some\n\t * browsers.\n\t *\n\t * ## This feels like too much overhead\n\t *\n\t * It's important to remember that SCE only applies to interpolation expressions.\n\t *\n\t * If your expressions are constant literals, they're automatically trusted and you don't need to\n\t * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.\n\t * `
implicitly trusted'\">
`) just works.\n\t *\n\t * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them\n\t * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.\n\t *\n\t * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load\n\t * templates in `ng-include` from your application's domain without having to even know about SCE.\n\t * It blocks loading templates from other domains or loading templates over http from an https\n\t * served document. You can change these by setting your own custom {@link\n\t * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link\n\t * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.\n\t *\n\t * This significantly reduces the overhead. It is far easier to pay the small overhead and have an\n\t * application that's secure and can be audited to verify that with much more ease than bolting\n\t * security onto an application later.\n\t *\n\t * \n\t * ## What trusted context types are supported?\n\t *\n\t * | Context | Notes |\n\t * |---------------------|----------------|\n\t * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |\n\t * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. |\n\t * | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`
Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |\n\t * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. |\n\t *\n\t * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} \n\t *\n\t * Each element in these arrays must be one of the following:\n\t *\n\t * - **'self'**\n\t * - The special **string**, `'self'`, can be used to match against all URLs of the **same\n\t * domain** as the application document using the **same protocol**.\n\t * - **String** (except the special value `'self'`)\n\t * - The string is matched against the full *normalized / absolute URL* of the resource\n\t * being tested (substring matches are not good enough.)\n\t * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters\n\t * match themselves.\n\t * - `*`: matches zero or more occurrences of any character other than one of the following 6\n\t * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use\n\t * in a whitelist.\n\t * - `**`: matches zero or more occurrences of *any* character. As such, it's not\n\t * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g.\n\t * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might\n\t * not have been the intention.) Its usage at the very end of the path is ok. (e.g.\n\t * http://foo.example.com/templates/**).\n\t * - **RegExp** (*see caveat below*)\n\t * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax\n\t * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to\n\t * accidentally introduce a bug when one updates a complex expression (imho, all regexes should\n\t * have good test coverage). For instance, the use of `.` in the regex is correct only in a\n\t * small number of cases. A `.` character in the regex used when matching the scheme or a\n\t * subdomain could be matched against a `:` or literal `.` that was likely not intended. It\n\t * is highly recommended to use the string patterns and only fall back to regular expressions\n\t * as a last resort.\n\t * - The regular expression must be an instance of RegExp (i.e. not a string.) It is\n\t * matched against the **entire** *normalized / absolute URL* of the resource being tested\n\t * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags\n\t * present on the RegExp (such as multiline, global, ignoreCase) are ignored.\n\t * - If you are generating your JavaScript from some other templating engine (not\n\t * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),\n\t * remember to escape your regular expression (and be aware that you might need more than\n\t * one level of escaping depending on your templating engine and the way you interpolated\n\t * the value.) Do make use of your platform's escaping mechanism as it might be good\n\t * enough before coding your own. E.g. Ruby has\n\t * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)\n\t * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).\n\t * Javascript lacks a similar built in function for escaping. Take a look at Google\n\t * Closure library's [goog.string.regExpEscape(s)](\n\t * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).\n\t *\n\t * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.\n\t *\n\t * ## Show me an example using SCE.\n\t *\n\t * \n\t * \n\t *

There is little value is mocking these out for this\n\t// service.\n\tvar urlParsingNode = document.createElement(\"a\");\n\tvar originUrl = urlResolve(window.location.href);\n\n\n\t/**\n\t *\n\t * Implementation Notes for non-IE browsers\n\t * ----------------------------------------\n\t * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,\n\t * results both in the normalizing and parsing of the URL. Normalizing means that a relative\n\t * URL will be resolved into an absolute URL in the context of the application document.\n\t * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related\n\t * properties are all populated to reflect the normalized URL. This approach has wide\n\t * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See\n\t * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n\t *\n\t * Implementation Notes for IE\n\t * ---------------------------\n\t * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other\n\t * browsers. However, the parsed components will not be set if the URL assigned did not specify\n\t * them. (e.g. if you assign a.href = \"foo\", then a.protocol, a.host, etc. will be empty.) We\n\t * work around that by performing the parsing in a 2nd step by taking a previously normalized\n\t * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the\n\t * properties such as protocol, hostname, port, etc.\n\t *\n\t * References:\n\t * http://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorElement\n\t * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html\n\t * http://url.spec.whatwg.org/#urlutils\n\t * https://github.com/angular/angular.js/pull/2902\n\t * http://james.padolsey.com/javascript/parsing-urls-with-the-dom/\n\t *\n\t * @kind function\n\t * @param {string} url The URL to be parsed.\n\t * @description Normalizes and parses a URL.\n\t * @returns {object} Returns the normalized URL as a dictionary.\n\t *\n\t * | member name | Description |\n\t * |---------------|----------------|\n\t * | href | A normalized version of the provided URL if it was not an absolute URL |\n\t * | protocol | The protocol including the trailing colon |\n\t * | host | The host and port (if the port is non-default) of the normalizedUrl |\n\t * | search | The search params, minus the question mark |\n\t * | hash | The hash string, minus the hash symbol\n\t * | hostname | The hostname\n\t * | port | The port, without \":\"\n\t * | pathname | The pathname, beginning with \"/\"\n\t *\n\t */\n\tfunction urlResolve(url) {\n\t var href = url;\n\n\t if (msie) {\n\t // Normalize before parse.

For example `{name:\"M\", phone:\"1\"}` predicate will return an array of items\n\t * which have property `name` containing \"M\" and property `phone` containing \"1\". A special\n\t * property name `$` can be used (as in `{$:\"text\"}`) to accept a match against any\n\t * property of the object or its nested object properties.

An expression can be\n\t * optionally prefixed with `+` or `-` to control ascending or descending sort order\n\t * (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array\n\t * element itself is used to compare where sorting.\n\t * - `Array`: An array of function or string predicates.

This means that the outer form is valid when all of the child\n\t * forms are valid as well. However, browsers do not allow nesting of `` elements, so\n\t * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to\n\t * `` but can be nested. This allows you to have nested forms, which is very useful when\n\t * using Angular validation directives in forms that are dynamically generated using the\n\t * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`\n\t * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an\n\t * `ngForm` directive and nest these in an outer `form` element.\n\t *\n\t *\n\t * # CSS classes\n\t * - `ng-valid` is set if the form is valid.\n\t * - `ng-invalid` is set if the form is invalid.\n\t * - `ng-pending` is set if the form is pending.\n\t * - `ng-pristine` is set if the form is pristine.\n\t * - `ng-dirty` is set if the form is dirty.\n\t * - `ng-submitted` is set if the form was submitted.\n\t *\n\t * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n\t *\n\t *\n\t * # Submitting a form and preventing the default action\n\t *\n\t * Since the role of forms in client-side Angular applications is different than in classical\n\t * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n\t * page reload that sends the data to the server. Instead some javascript logic should be triggered\n\t * to handle the form submission in an application-specific way.\n\t *\n\t * For this reason, Angular prevents the default action (form submission to the server) unless the\n\t * `` element has an `action` attribute specified.\n\t *\n\t * You can use one of the following two ways to specify what javascript method should be called when\n\t * a form is submitted:\n\t *\n\t * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n\t * - {@link ng.directive:ngClick ngClick} directive on the first\n\t * button or input field of type submit (input[type=submit])\n\t *\n\t * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n\t * or {@link ng.directive:ngClick ngClick} directives.\n\t * This is because of the following form submission rules in the HTML specification:\n\t *\n\t * - If a form has only one input field then hitting enter in this field triggers form submit\n\t * (`ngSubmit`)\n\t * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n\t * doesn't trigger submit\n\t * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n\t * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n\t * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n\t *\n\t * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n\t * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n\t * to have access to the updated model.\n\t *\n\t * ## Animation Hooks\n\t *\n\t * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n\t * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n\t * other validations that are performed within the form. Animations in ngForm are similar to how\n\t * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n\t * as JS animations.\n\t *\n\t * The following example shows a simple way to utilize CSS transitions to style a form element\n\t * that has been rendered as invalid after it has been validated:\n\t *\n\t * 
\n\t * //be sure to include ngAnimate as a module to hook into more\n\t * //advanced animations\n\t * .my-form {\n\t *   transition:0.5s linear all;\n\t *   background: white;\n\t * }\n\t * .my-form.ng-invalid {\n\t *   background: red;\n\t *   color:white;\n\t * }\n\t *
\n\t *\n\t * @example\n\t \n\t \n\t \n\t \n\t \n\t userType: \n\t Required!
\n\t userType = {{userType}}
\n\t myForm.input.$valid = {{myForm.input.$valid}}

\n\t myForm.$valid = {{myForm.$valid}}
\n\t myForm.$error.required = {{!!myForm.$error.required}}

Setting the attribute to a negative or non-numeric value, allows view values of\n\t * any length.\n\t * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string\n\t * that contains the regular expression body that will be converted to a regular expression\n\t * as in the ngPattern directive.\n\t * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match\n\t * a RegExp found by evaluating the Angular expression given in the attribute value.\n\t * If the expression evaluates to a RegExp object, then this is used directly.\n\t * If the expression evaluates to a string, then it will be converted to a RegExp\n\t * after wrapping it in `^` and `$` characters. For instance, `\"abc\"` will be converted to\n\t * `new RegExp('^abc$')`.
\n\t * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to\n\t * start at the index of the last search's match, thus not taking the whole input value into\n\t * account.\n\t * @param {string=} ngChange Angular expression to be executed when input changes due to user\n\t * interaction with the input element.\n\t *\n\t * @example\n\t \n\t \n\t \n\t

\n\t *\n\t * @param {string} ngModel Assignable angular expression to data-bind to.\n\t * @param {string=} name Property name of the form under which the control is published.\n\t * @param {string=} required Sets `required` validation error key if the value is not entered.\n\t * @param {boolean=} ngRequired Sets `required` attribute if set to true\n\t * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than\n\t * minlength.\n\t * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than\n\t * maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any\n\t * length.\n\t * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match\n\t * a RegExp found by evaluating the Angular expression given in the attribute value.\n\t * If the expression evaluates to a RegExp object, then this is used directly.\n\t * If the expression evaluates to a string, then it will be converted to a RegExp\n\t * after wrapping it in `^` and `$` characters. For instance, `\"abc\"` will be converted to\n\t * `new RegExp('^abc$')`.
\n\t * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to\n\t * start at the index of the last search's match, thus not taking the whole input value into\n\t * account.\n\t * @param {string=} ngChange Angular expression to be executed when input changes due to user\n\t * interaction with the input element.\n\t * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.\n\t * This parameter is ignored for input[type=password] controls, which will never trim the\n\t * input.\n\t *\n\t * @example\n\t \n\t \n\t \n\t
