This reflects whether or not History.js is enabled for our particular browser. For instance, if we have not included support for a HTML4 browser and we are accessing through a HTML4 browser then `History.enabled` will be `false`. - Added (optional but recommended) Data Persistance and Synchronisation Support thanks to [AppendTo's](http://appendto.com/) [Amplify.js](http://amplifyjs.com/) (refer to installation and compatibility sections for details) - Made HTML5 SUIDs more transparent - [Reported](https://github.com/balupton/history.js/issues#issue/34) by [azago](https://github.com/azago) and [Mark Jaquith](http://markjaquith.com/) - Fixed Session Storage Issue - Reported by a whole bunch of different people; [one](https://github.com/balupton/history.js/issues#issue/36), [two](https://github.com/balupton/history.js/issues#issue/37), [three](http://getsatisfaction.com/balupton/topics/history_js_1_6_losing_state_after_manual_page_reload) - Fixed URL Encoding Issue - [Reported](https://github.com/balupton/history.js/issues/#issue/33) by [Rob Madole](http://robmadole.com/) - Disabled support for IE6,7,8 when using the Prototype Adapter (there is nothing we can do about this, it is due to a bug in the prototype library) - [Reported](https://github.com/balupton/history.js/issues#issue/39) by [Sindre Wimberger](http://sindre.at/) - URLs in the State Hashes for HTML4 Browsers are now even shorter - [Discussion](https://github.com/balupton/history.js/issues#issue/28) - Fixed a issue with the MooTools Adapter and JSON with IE7 and IE8 - v1.6.0 - March 22 2011 - Added Zepto adapter thanks to [Matt Garrett](http://twitter.com/#!/matthewgarrett) - The readme now references the supported versions of the libraries we use - Updated vendors to the most recent versions. jQuery 1.5.1 and Mootools 1.3.1 - Reverted versions of Safari iOS prior to version 4.3 to be HTML4 browsers, Safari iOS 4.3 is a HTML5 browser - Refined code in History.js and its adapters - Fixed issue with extra state being inserted on Safari 5 requiring an extra click on the back button to go home - [Reported](https://github.com/balupton/history.js/issues#issue/17) by [Rob Madole](http://robmadole.com/) - Fixed issue with Safari 5 and Safari iOS 4 sometimes failing to apply the state change under busy conditions - Solution conceived with [Matt Garrett](http://twitter.com/matthewgarrett) - Fixed issue with HTML4 browsers requiring a query-string in the urls of states - [Reported](https://github.com/balupton/history.js/issues#issue/26) by [azago](https://github.com/azago) - Fixed issue with HTML4 browsers requiring title in the states in order to use state data - [Reported](https://github.com/balupton/history.js/issues#issue/25) by [Jonathan McLaughlin](http://system-werks.com/) - Fixed issue with HTML4 browsers failing is a state is pushed/replaced twice in a row - [Reported](https://github.com/balupton/history.js/issues#issue/17) by [Joey Baker](http://byjoeybaker.com/) - **B/C BREAK:** The `statechange` event now only fires if the state has changed; it no longer fires on page initialisation. This is following the [Firefox 4 History API Changes](http://hacks.mozilla.org/2011/03/history-api-changes-in-firefox-4/) which we agree with - this breaks standard, but makes more sense. - v1.5.0 - February 12 2011 - Moved to UglifyJS instead of Google Closure - Split HTML4 functionality from HTML5 functionality - Installation details have changed (the filenames are different) - v1.4.1 - February 10 2011 - Added HTML History API Support for Safari 5 and Safari iOS 4.2.1 - Cleaned code a bit (mostly with unit tests) - v1.4.0 - February 10 2011 - Unit Testing now uses [QUnit](http://docs.jquery.com/Qunit) - Corrected Safari 5 Support - Now uses queues instead of timeouts - This means the API works exactly as expected, no more need to wrap calls in timeouts - Included a Subscribe Form in the Demo for Version Updates via Email - Small updates to Documentation - v1.3.1 - February 4 2011 - Improved Documentation - v1.3.0 - January 31 2011 - Support for cleaner HTML4 States - v1.2.1 - January 30 2011 - Fixed History.log always being called - [reported by dlee](https://github.com/balupton/history.js/issues/#issue/2) - Re-Added `History.go(index)` support - v1.2.0 - January 25 2011 - Support for HTML4 States in HTML5 Browsers (added test) - Updates of Documentation - v1.1.0 - January 24 2011 - Developed a series of automated test cases - Fixed issue with traditional anchors - Fixed issue with differing replaceState functionality in HTML4 Browsers - Fixed issue with Google Chrome artefacts being carried over to the initial state - Provided `onstatechange` and `onanchorchange` events - v1.0.0 - January 22 2011 - Supported `History.pushState` and `History.replaceState` degradation - Supported jQuery, MooTools and Prototype Frameworks ================================================ FILE: LICENSE.md ================================================ # License Copyright © 2014+ Bevry Pty Ltd (http://bevry.me)

If you intend to support legacy browsers, then History.js is your bet. This notice is here as History.js does not receive enough funding to be maintained, so it exists only in legacy condition for legacy browsers. Perhaps it still works for modern browsers, but it could really do with maintenance. Maintenance is very difficult as the library requires manual testing in HTML5 and HTML4 modes, and for each adapter, and for each browser. So that means `2^(# of adapters)^(# of browsers and their versions)` tests that need to be run by a human. Tests need to be run by a human as certain failures require browser interactions, such as navigating from the test suite to a different domain and back again, or clicking the physical back buttons, or checking if the physical back buttons actually work. This takes a lot of time. Despite History.js being one of the most popular JavaScript libraries there is, and has been used by even multi-million-user companies in its time - the reality of economy and company practices seems to be that companies prefer to fork their own internal versions and fix locally with their own devs rather than fund open-source maintainers what they would pay their own devs to make things better for everyone, including themselves, which would be cheaper - but no, that would require too many tiers of company approval that don't understand the need. As such, if you are an open-source developer, I'd recommend just working on open-source projects that are paid for by your own consulting work or your own company (e.g. every successful open-source project). As otherwise, when they become popular, you better hope they are easily maintainable and testable, otherwise the cost of maintenance is higher than the free time of the maintainers. So with all that said, this repo still exists for archival purposes, legacy browsers, and a hub for anarachistic issue & fork maintenance.

Tests updated. - 21/01/2013: Alpha 2 of v1.8 is released. Correct statechange behaviour. - 19/01/2013: Alpha 1 of v1.8 is released. Started to categorize old balupton's issues. ### History [See the `HISTORY.md` file for a detailed list of features, changes, solved issues and bugs](https://github.com/browserstate/history.js/blob/master/HISTORY.md#files) ### Involve Please create an issue if something doesn't work or if there is a browser specific bug. I'll try to fix it as soon as possible. Please send me your Pull requests if you have a nice solution! I'm also going to review old issues in balupton's repository and try to solve them too. ## Aims - Follow the [HTML5 History API](https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history) as much as possible - Provide a cross-compatible experience for all HTML5 Browsers (they all implement the HTML5 History API a little bit differently causing different behaviours and sometimes bugs - History.js fixes this ensuring the experience is as expected / the same / great throughout the HTML5 browsers) - Provide a backwards-compatible experience for all HTML4 Browsers using a hash-fallback (including continued support for the HTML5 History API's `data`, `title`, `pushState` and `replaceState`) with the option to [remove HTML4 support if it is not right for your application](https://github.com/browserstate/history.js/wiki/Intelligent-State-Handling) - Provide a forwards-compatible experience for HTML4 States to HTML5 States (so if a hash-fallbacked url is accessed by a HTML5 browser it is naturally transformed into its non-hashed url equivalent) - Provide support for as many javascript frameworks as possible via adapters; especially [Dojo](http://dojotoolkit.org/), [ExtJS](http://www.sencha.com/), [jQuery](http://jquery.com/), [MooTools](http://mootools.net/), [Right.js](http://rightjs.org/) and [Zepto](http://zeptojs.com/). ## Quick Install ### Via Ajaxify Script To ajaxify your entire website with the HTML5 History API, History.js and jQuery the [Ajaxify script](https://github.com/browserstate/ajaxify) is all you need. It's that easy. ### Via Ajaxify Extension If you don't have access to your server, or just want to try out the Ajaxify script first, you can install the [History.js It! Google Chrome Extension](https://github.com/browserstate/historyjsit.crx) to try out History.js via Ajaxify on select websites without actually installing History.js/Ajaxify on your server. ### Via Ruby On Rails Gem If you are using Rails, then the easiest way for you to try History.js would be to use [Wiselinks](https://github.com/igor-alexandrov/wiselinks) gem. Wiselinks integrates into Rails application and allows you to start using History.js with three lines of code. ## Direct Install ### Working with History.js directly ``` javascript (function(window,undefined){ // Bind to StateChange Event History.Adapter.bind(window,'statechange',function(){ // Note: We are using statechange instead of popstate var State = History.getState(); // Note: We are using History.getState() instead of event.state }); // Change our States History.pushState({state:1}, "State 1", "?state=1"); // logs {state:1}, "State 1", "?state=1" History.pushState({state:2}, "State 2", "?state=2"); // logs {state:2}, "State 2", "?state=2" History.replaceState({state:3}, "State 3", "?state=3"); // logs {state:3}, "State 3", "?state=3" History.pushState(null, null, "?state=4"); // logs {}, '', "?state=4" History.back(); // logs {state:3}, "State 3", "?state=3" History.back(); // logs {state:1}, "State 1", "?state=1" History.back(); // logs {}, "Home Page", "?" History.go(2); // logs {state:3}, "State 3", "?state=3" })(window); ``` ### How would the above operations look in a HTML5 Browser? 1. www.mysite.com 1. www.mysite.com/?state=1 1. www.mysite.com/?state=2 1. www.mysite.com/?state=3 1. www.mysite.com/?state=4 1. www.mysite.com/?state=3 1. www.mysite.com/?state=1 1. www.mysite.com 1. www.mysite.com/?state=3 > Note: These urls also work in HTML4 browsers and Search Engines. So no need for the hashbang (`#!`) fragment-identifier that google ["recommends"](https://github.com/browserstate/history.js/wiki/Intelligent-State-Handling). ### How would they look in a HTML4 Browser? 1. www.mysite.com 1. www.mysite.com/#?state=1&_suid=1 1. www.mysite.com/#?state=2&_suid=2 1. www.mysite.com/#?state=3&_suid=3 1. www.mysite.com/#?state=4 1. www.mysite.com/#?state=3&_suid=3 1. www.mysite.com/#?state=1&_suid=1 1. www.mysite.com 1. www.mysite.com/#?state=3&_suid=3 > Note 1: These urls also work in HTML5 browsers - we use `replaceState` to transform these HTML4 states into their HTML5 equivalents so the user won't even notice :-) > > Note 2: These urls will be automatically url-encoded in IE6 to prevent certain browser-specific bugs. > > Note 3: Support for HTML4 browsers (this hash fallback) is optional [- why supporting HTML4 browsers could be either good or bad based on my app's use cases](https://github.com/browserstate/history.js/wiki/Intelligent-State-Handling) ### What's the deal with the SUIDs used in the HTML4 States? - SUIDs (State Unique Identifiers) are used when we utilise a `title` and/or `data` in our state. Adding a SUID allows us to associate particular states with data and titles while keeping the urls as simple as possible (don't worry it's all tested, working and a lot smarter than I'm making it out to be). - If you aren't utilising `title` or `data` then we don't even include a SUID (as there is no need for it) - as seen by State 4 above :-) - We also shrink the urls to make sure that the smallest url will be used. For instance we will adjust `http://www.mysite.com/#http://www.mysite.com/projects/History.js` to become `http://www.mysite.com/#/projects/History.js` automatically. (again tested, working, and smarter). - It works with domains, subdomains, subdirectories, whatever - doesn't matter where you put it. It's smart. - Safari 5 will also have a SUID appended to the URL, it is entirely transparent but just a visible side-effect. It is required to fix a bug with Safari 5. ### Is there a working demo? - Sure is, give it a download and navigate to the demo directory in your browser :-) - If you are after something a bit more adventurous than a end-user demo, open up the tests directory in your browser and editor - it'll rock your world and show all the vast use cases that History.js supports. ## Download & Installation - Download History.js and upload it to your webserver. Download links: [tar.gz](https://github.com/browserstate/history.js/tarball/master) or [zip](https://github.com/browserstate/history.js/zipball/master) - Include History.js - For [Dojo](http://dojotoolkit.org/) v1.8+ ``` html ``` - For [ExtJs](http://www.sencha.com/) v1.8+ ``` html ``` - For [jQuery](http://jquery.com/) v1.3+ ``` html ``` - For [Mootools](http://mootools.net/) v1.3+ ``` html ``` - For [Right.js](http://rightjs.org/) v2.2+ ``` html ``` - For [Zepto](http://zeptojs.com/) v0.5+ ``` html ``` - For everything else ``` html ``` > Note: If you want to only support HTML5 Browsers and not HTML4 Browsers (so no hash fallback support) then just change the `/html4+html5/` part in the urls to just `/html5/`. See [Why supporting HTML4 browsers could be either good or bad based on my app's use cases](https://github.com/browserstate/history.js/wiki/Intelligent-State-Handling) ## Get Updates - For Commit RSS/Atom Updates: - You can subscribe via the [GitHub Commit Atom Feed](http://feeds.feedburner.com/historyjs) - For GitHub News Feed Updates: - You can click the "watch" button up the top right of History.js's [GitHub Project Page](https://github.com/browserstate/history.js) ## Get Support - History.js is maintained by people like you.

Thanks! every bit of help really does make a difference! ## Browsers: Tested and Working In ### HTML5 Browsers - Firefox 4+ - Chrome 8+ - Opera 11.5+ - Safari 5.0+ - Safari iOS 4.3+ ### HTML4 Browsers - IE 6, 7, 8, 9, (10) - Firefox 3 - Opera 10, 11.0 - Safari 4 - Safari iOS 4.2, 4.1, 4.0, 3.2 ## Exposed API ### Functions #### States - `History.pushState(data,title,url)`
Pushes a new state to the browser; `data` can be null or an object, `title` can be null or a string, `url` must be a string - `History.replaceState(data,title,url)`
Replaces the existing state with a new state to the browser; `data` can be null or an object, `title` can be null or a string, `url` must be a string - `History.getState()`
Gets the current state of the browser, returns an object with `data`, `title` and `url` - `History.getStateByIndex`
Gets a state by the index - `History.getCurrentIndex`
Gets the current index - `History.getHash()`
Gets the current hash of the browser #### Adapter - `History.Adapter.bind(element,event,callback)`
A framework independent event binder, you may either use this or your framework's native event binder. - `History.Adapter.trigger(element,event)`
A framework independent event trigger, you may either use this or your framework's native event trigger. - `History.Adapter.onDomLoad(callback)`
A framework independent onDomLoad binder, you may either use this or your framework's native onDomLoad binder. #### Navigation - `History.back()`
Go back once through the history (same as hitting the browser's back button) - `History.forward()`
Go forward once through the history (same as hitting the browser's forward button) - `History.go(X)`
If X is negative go back through history X times, if X is positive go forwards through history X times #### Debug - `History.log(...)`
Logs messages to the console, the log element, and fallbacks to alert if neither of those two exist - `History.debug(...)`
Same as `History.log` but only runs if `History.options.debug === true` ### Options - `History.options.hashChangeInterval`
How long should the interval be before hashchange checks - `History.options.safariPollInterval`
How long should the interval be before safari poll checks - `History.options.doubleCheckInterval`
How long should the interval be before we perform a double check - `History.options.disableSuid`
Force History not to append suid - `History.options.storeInterval`
How long should we wait between store calls - `History.options.busyDelay`
How long should we wait between busy events - `History.options.debug`
If true will enable debug messages to be logged - `History.options.initialTitle`
What is the title of the initial state - `History.options.html4Mode`
If true, will force HTMl4 mode (hashtags) - `History.options.delayInit`
Want to override default options and call init manually. ### Events - `window.onstatechange`
Fired when the state of the page changes (does not include hash changes) - `window.onanchorchange`
Fired when the anchor of the page changes (does not include state hashes) ## Known Issues - Opera 11 fails to create history entries when under stressful loads (events fire perfectly, just the history events fail) - there is nothing we can do about this - Mercury iOS fails to apply url changes (hashes and HTML5 History API states) - there is nothing we can do about this ## Notes on Compatibility - History.js **solves** the following browser bugs: - HTML5 Browsers - Chrome 8 sometimes does not contain the correct state data when traversing back to the initial state - Safari 5, Safari iOS 4 and Firefox 3 and 4 do not fire the `onhashchange` event when the page is loaded with a hash - Safari 5 and Safari iOS 4 do not fire the `onpopstate` event when the hash has changed unlike the other browsers - Safari 5 and Safari iOS 4 fail to return to the correct state once a hash is replaced by a `replaceState` call / [bug report](https://bugs.webkit.org/show_bug.cgi?id=56249) - Safari 5 and Safari iOS 4 sometimes fail to apply the state change under busy conditions / [bug report](https://bugs.webkit.org/show_bug.cgi?id=42940) - Google Chrome 8,9,10 and Firefox 4 prior to the RC will always fire `onpopstate` once the page has loaded / [change recommendation](http://hacks.mozilla.org/2011/03/history-api-changes-in-firefox-4/) - Safari iOS 4.0, 4.1, 4.2 have a working HTML5 History API - although the actual back buttons of the browsers do not work, therefore we treat them as HTML4 browsers - None of the HTML5 browsers actually utilise the `title` argument to the `pushState` and `replaceState` calls - HTML4 Browsers - Old browsers like MSIE 6,7 and Firefox 2 do not have a `onhashchange` event - MSIE 6 and 7 sometimes do not apply a hash even it was told to (requiring a second call to the apply function) - Non-Opera HTML4 browsers sometimes do not apply the hash when the hash is not `urlencoded` - All Browsers - State data and titles do not persist once the site is left and then returned (includes page refreshes) - State titles are never applied to the `document.title` - ReplaceState functionality is emulated in HTML4 browsers by discarding the replaced state, so when the discarded state is accessed it is skipped using the appropriate `History.back()` / `History.forward()` call - Data persistance and synchronisation works like so: Every second or so, the SUIDs and URLs of the states will synchronise between the store and the local session. When a new session opens a familiar state (via the SUID or the URL) and it is not found locally then it will attempt to load the last known stored state with that information. - URLs will be unescaped to the maximum, so for instance the URL `?key=a%20b%252c` will become `?key=a b c`. This is to ensure consistency between browser url encodings. - Changing the hash of the page causes `onpopstate` to fire (this is expected/standard functionality). To ensure correct compatibility between HTML5 and HTML4 browsers the following events have been created: - `window.onstatechange`: this is the same as the `onpopstate` event except it does not fire for traditional anchors - `window.onanchorchange`: this is the same as the `onhashchange` event except it does not fire for states ## License Licensed under the [New BSD License](http://opensource.org/licenses/BSD-3-Clause)

There's a bug in the HTML5 "popstate" event, as implemented in WebKit (Safari and Chrome). View this page in one of those browsers. Your browser has had history entries added from #0 to #19 (you should start at #19). Hitting back/forward will navigate through these. On each URL, the large number above should reflect the hash value. If you hit back/forward quickly, you'll notice that your number gets out of sync with the URL. This is because WebKit is dropping popstate events (they are not firing). It seems to happen when outbound network requests are in progress when the user navigates in their browser happens. In this case, your browser is downloading an image that takes 1s to serve on every popstate, so you'll have to wait 1s between backs/forwards to have the feature work correctly. You could also cause constant network traffic by putting an image download in a setInterval, in which case your popstate events will never fire. This implementation simulates an AJAX application that makes a network request when you navigate between URLs using pushState/popstate. View the source for more info.

This was filed as Bug 42940 with WebKit on July 24, 2010. The Firefox 4 beta does not have this bug, which is good news.

================================================ FILE: demo/chrome.html ================================================ Chrome History API Data Artifact

This demo demonstrates an issue with Google Chrome versions 8-10 (possibly 11) where if you push a state with data, then do history.back to the initial state, the event.state will contain the pushed states data instead of being null.

Note: The issue requires a clean history list, as such this should always be opened in a new tab/window where there are no prior history items.

Reported by Benjamin Lupton author of History.js

================================================ FILE: demo/index.html ================================================ History.js

History.js

History.js gracefully supports the HTML5 History/State APIs (pushState, replaceState, onPopState) in all browsers. Including continued support for data, titles, replaceState. Supports jQuery, MooTools and Prototype. For HTML5 browsers this means that you can modify the URL directly, without needing to use hashes anymore. For HTML4 browsers it will revert back to using the old onhashchange functionality.

Click through the buttons in order and you'll get the results demonstrated in the README.md file.

This demo demonstrates an issue with Safari 5.0.4 (6533.20.27) handing of hashes and replace state. When a hash is set, and then replaced using replaceState the history list are then broken, when traversing back the hash does not change.

Note: The issue requires a clean history list, as such this should always be opened in a new tab/window where there are no prior history items.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This code should be minified before deployment. See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results.

However, this // should only happen in the case where you do dojo.require calls in the top-level // HTML page, or if you purposely avoid the loader checking for dojo.require // dependencies in your module by using a syntax like dojo["require"] to load the module. // // Sometimes it is useful to not have the loader detect the dojo.require calls in the // module so that you can dynamically load the modules as a result of an action on the // page, instead of right at module load time. // // Also, for script blocks in an HTML page, the loader does not pre-process them, so // it does not know to download the modules before the dojo.require calls occur. // // So, in those two cases, when you want on-the-fly module loading or for script blocks // in the HTML page, special care must be taken if the dojo.required code is loaded // asynchronously. To make sure you can execute code that depends on the dojo.required // modules, be sure to add the code that depends on the modules in a dojo.addOnLoad() // callback. dojo.addOnLoad waits for all outstanding modules to finish loading before // executing. // // This type of syntax works with both xdomain and normal loaders, so it is good // practice to always use this idiom for on-the-fly code loading and in HTML script // blocks. If at some point you change loaders and where the code is loaded from, // it will all still work. // // More on how dojo.require // `dojo.require("A.B")` first checks to see if symbol A.B is // defined. If it is, it is simply returned (nothing to do). // // If it is not defined, it will look for `A/B.js` in the script root // directory. // // `dojo.require` throws an exception if it cannot find a file // to load, or if the symbol `A.B` is not defined after loading. // // It returns the object `A.B`, but note the caveats above about on-the-fly loading and // HTML script blocks when the xdomain loader is loading a module. // // `dojo.require()` does nothing about importing symbols into // the current namespace. It is presumed that the caller will // take care of that. // // example: // To use dojo.require in conjunction with dojo.ready: // // | dojo.require("foo"); // | dojo.require("bar"); // | dojo.addOnLoad(function(){ // | //you can now safely do something with foo and bar // | }); // // example: // For example, to import all symbols into a local block, you might write: // // | with (dojo.require("A.B")) { // | ... // | } // // And to import just the leaf symbol to a local variable: // // | var B = dojo.require("A.B"); // | ... // // returns: // the required namespace object function doRequire(mid, omitModuleCheck){ var module = getModule(slashName(mid), require.module); if(syncExecStack.length && syncExecStack[0].finish){ // switched to async loading in the middle of evaluating a legacy module; stop // applying dojo.require so the remaining dojo.requires are applied in order syncExecStack[0].finish.push(mid); return undefined; } // recall module.executed has values {0, executing, executed}; therefore, truthy indicates executing or executed if(module.executed){ return module.result; } omitModuleCheck && (module.result = nonmodule); // rcg...why here and in two lines?? var currentMode = getLegacyMode(); // recall, in sync mode to inject is to *eval* the module text // if the module is a legacy module, this is the same as executing // but if the module is an AMD module, this means defining, not executing injectModule(module); // the inject may have changed the mode currentMode = getLegacyMode(); // in sync mode to dojo.require is to execute if(module.executed!==executed && module.injected===arrived){ // the module was already here before injectModule was called probably finishing up a xdomain // load, but maybe a module given to the loader directly rather than having the loader retrieve it loaderVars.guardCheckComplete(function(){ execModule(module); }); } if(module.executed){ return module.result; } if(currentMode==sync){ // the only way to get here is in sync mode and dojo.required a module that // * was loaded async in the injectModule application a few lines up // * was an AMD module that had deps that are being loaded async and therefore couldn't execute if(module.cjs){ // the module was an AMD module; unshift, not push, which causes the current traversal to be reattempted from the top execQ.unshift(module); }else{ // the module was a legacy module syncExecStack.length && (syncExecStack[0].finish= [mid]); } }else{ // the loader wasn't in sync mode on entry; probably async mode; therefore, no expectation of getting // the module value synchronously; make sure it gets executed though execQ.push(module); } return undefined; } var result = doRequire(moduleName, omitModuleCheck); if(has("config-publishRequireResult") && !lang.exists(moduleName) && result!==undefined){ lang.setObject(moduleName, result); } return result; }; dojo.loadInit = function(f) { f(); }; dojo.registerModulePath = function(/*String*/moduleName, /*String*/prefix){ // summary: // Maps a module name to a path // description: // An unregistered module is given the default path of ../[module], // relative to Dojo root.

If a hint string is // "before", this method will be called before methods of its base // classes. // // If "constructor" is not mentioned in "-chains-" property, it will // be chained using the legacy mode: using "after" chaining, // calling preamble() method before each constructor, if available, // and calling postscript() after all constructors were executed. // If the hint is "after", it is chained as a regular method, but // postscript() will be called after the chain of constructors. // "constructor" cannot be chained "before", but it allows // a special hint string: "manual", which means that constructors // are not going to be chained in any way, and programmer will call // them manually using this.inherited(). In the latter case // postscript() will be called after the construction. // // All chaining hints are "inherited" from base classes and // potentially can be overridden. Be very careful when overriding // hints! Make sure that all chained methods can work in a proposed // manner of chaining. // // Once a method was chained, it is impossible to unchain it.

It is designed to take any valid CSS3 selector and return the nodes matching the selector. To do this quickly, it processes queries in several steps, applying caching where profitable. The steps (roughly in reverse order of the way they appear in the code): 1.) check to see if we already have a "query dispatcher" - if so, use that with the given parameterization. Skip to step 4. 2.) attempt to determine which branch to dispatch the query to: - JS (optimized DOM iteration) - native (FF3.1+, Safari 3.1+, IE 8+) 3.) tokenize and convert to executable "query dispatcher" - this is where the lion's share of the complexity in the system lies. In the DOM version, the query dispatcher is assembled as a chain of "yes/no" test functions pertaining to a section of a simple query statement (".blah:nth-child(odd)" but not "div div", which is 2 simple statements). Individual statement dispatchers are cached (to prevent re-definition) as are entire dispatch chains (to make re-execution of the same query fast) 4.) the resulting query dispatcher is called in the passed scope (by default the top-level document) - for DOM queries, this results in a recursive, top-down evaluation of nodes based on each simple query section - for native implementations, this may mean working around spec bugs. So be it. 5.) matched nodes are pruned to ensure they are unique (if necessary) */ //////////////////////////////////////////////////////////////////////// // Toolkit aliases //////////////////////////////////////////////////////////////////////// // if you are extracting acme for use in your own system, you will // need to provide these methods and properties.

Much like Prototype's "$$" (bling-bling) function or JQuery's // "$" function, dojo.query provides robust, high-performance // CSS-based node selector support with the option of scoping searches // to a particular sub-tree of a document. // // Supported Selectors: // -------------------- // // acme supports a rich set of CSS3 selectors, including: // // - class selectors (e.g., `.foo`) // - node type selectors like `span` // - ` ` descendant selectors // - `>` child element selectors // - `#foo` style ID selectors // - `*` universal selector // - `~`, the preceded-by sibling selector // - `+`, the immediately preceded-by sibling selector // - attribute queries: // - `[foo]` attribute presence selector // - `[foo='bar']` attribute value exact match // - `[foo~='bar']` attribute value list item match // - `[foo^='bar']` attribute start match // - `[foo$='bar']` attribute end match // - `[foo*='bar']` attribute substring match // - `:first-child`, `:last-child`, and `:only-child` positional selectors // - `:empty` content emtpy selector // - `:checked` pseudo selector // - `:nth-child(n)`, `:nth-child(2n+1)` style positional calculations // - `:nth-child(even)`, `:nth-child(odd)` positional selectors // - `:not(...)` negation pseudo selectors // // Any legal combination of these selectors will work with // `dojo.query()`, including compound selectors ("," delimited). // Very complex and useful searches can be constructed with this // palette of selectors and when combined with functions for // manipulation presented by dojo/NodeList, many types of DOM // manipulation operations become very straightforward. // // Unsupported Selectors: // ---------------------- // // While dojo.query handles many CSS3 selectors, some fall outside of // what's reasonable for a programmatic node querying engine to // handle. Currently unsupported selectors include: // // - namespace-differentiated selectors of any form // - all `::` pseduo-element selectors // - certain pseudo-selectors which don't get a lot of day-to-day use: // - `:root`, `:lang()`, `:target`, `:focus` // - all visual and state selectors: // - `:root`, `:active`, `:hover`, `:visited`, `:link`, // `:enabled`, `:disabled` // - `:*-of-type` pseudo selectors // // dojo.query and XML Documents: // ----------------------------- // // `dojo.query` (as of dojo 1.2) supports searching XML documents // in a case-sensitive manner. If an HTML document is served with // a doctype that forces case-sensitivity (e.g., XHTML 1.1 // Strict), dojo.query() will detect this and "do the right // thing". Case sensitivity is dependent upon the document being // searched and not the query used. It is therefore possible to // use case-sensitive queries on strict sub-documents (iframes, // etc.) or XML documents while still assuming case-insensitivity // for a host/root document. // // Non-selector Queries: // --------------------- // // If something other than a String is passed for the query, // `dojo.query` will return a new `dojo/NodeList` instance // constructed from that parameter alone and all further // processing will stop. This means that if you have a reference // to a node or NodeList, you can quickly construct a new NodeList // from the original by calling `dojo.query(node)` or // `dojo.query(list)`. // // query: // The CSS3 expression to match against. For details on the syntax of // CSS3 selectors, see // root: // A DOMNode (or node id) to scope the search from. Optional. // returns: Array // example: // search the entire document for elements with the class "foo": // | dojo.query(".foo"); // these elements will match: // | // | // |

                                // example: // search the entire document for elements with the classes "foo" *and* "bar": // | dojo.query(".foo.bar"); // these elements will match: // | // while these will not: // | // |

                                // example: // find `` elements which are descendants of paragraphs and // which have a "highlighted" class: // | dojo.query("p span.highlighted"); // the innermost span in this fragment matches: // |

                                // | ... // | ... // | // |
