# [data.js](https://github.com/yanhaijing/data.js) [](https://travis-ci.org/yanhaijing/data.js) [](https://github.com/yanhaijing/data.js/blob/master/MIT-LICENSE.txt) [](https://github.com/yanhaijing/data.js/releases/tag/v0.3.0)
data.js 是带有消息通知的数据中心，我称其为会说话的数据。旨在让编程变得简单，世界变得美好。
## 特性
1. 全局数据中心，可以用来存放数据，在不同程序中共享。
2. 将程序的耦合度，变为数据耦合，采用隐式调用风格，发挥js事件风格。
## 兼容性
- Node 0.10+
- Safari 6+ (Mac)
- iOS 5+ Safari
- Chrome 23+ (Windows, Mac, Android, iOS, Linux, Chrome OS)
- Firefox 4+ (Windows, Mac, Android, Linux)
- Internet Explorer 6+ (Windows, Windows Phone)
- Opera 10+ (Windows, linux, Android)
## 下载
第一种方法，推荐使用npm安装和更新
$ npm install --save data_js
第二种方法，或者你也可以在GitHub，下载源文件或压缩包
## 如何使用？
支持全局变量、AMD、commonjs、es6等模块系统
### 传统用法
<script src="data.js"></script>
<script>
window.Data
</script>
### AMD
require(['data'], function (Data) {
Data
});
### commonjs
var Data = require('data_js')
## 快速上手
Data常用接口只有三个，非常简单：
```javascript
Data.sub('set', 'a', function (e) {console.log(e.data)});//订阅消息，当a被设置时，会派发消息
Data.set('a', 1);//存入数据
Data.get('a');//读取数据
```
更多例子，请见目录下的[demo](demo)目录。
## 文档
[API](doc/api.md)
## 质量保证
data.js的代码运行于ecmascript严格模式下，jshint验证，完整的单元测试，并使用travis保证。测试代码见test目录下。
## 性能
data.js的存入和取出，都是对数据的一次深拷贝，同时还要解析数据的键和派发消息，所以性能会有一些损失，但不涉及大批量循环存取不会遇到性能问题。
- [get接口性能](http://jsperf.com/yanhaijing-data-js-get)
- [set接口性能](http://jsperf.com/yanhaijing-data-js-set)
## 贡献指南
如果你想为data.js贡献代码，请采用fork + pull request 方式，并在发起pr前先将master上超前的代码rebase到自己的分支上。
在目录运行如下命令，完成验证测试编译过程，确保无误：
$ npm install -g mocha@~2.3.4 # 安装mocha
$ npm install # 安装依赖
$ mocha test # 运行测试代码
$ npm install -g gulp@~3.9.0 # 安装gulp
# gulp lint # 验证代码风格
### 发布npm
$ npm publish

#data.js
data.js在浏览器环境中默认占用全局变量Data，在模块化编程环境中，引用模块返回Data，返回的Data是一个数据中心+工厂函数，可直接将其作为一个数据中心使用，也可通过该函数创建新的数据中心。
//一下两种方式均可获取数据中心的实例
var D = Data();
var D = new Data();
//有一个数据中心，与上面的D无关系
var F = new Data();
//在实例化的数据中心上操作
F.set(***);
//在默认的数据中心上操作
Data.set(***);
##noConflict
此函数会在以原始方式在浏览器中引入是存在，用来释放Data占用的全局变量Data。同时返回Data。
- return {Function} Data
demo
var D = Data.noConflict();//释放Data，并赋值给D
##version
获取data.js的版本号，字符串，仅在Data上存在。
console.log(Data.version);//0.1.0
console.log(Data().version);//undefined
##has
判断Data中是否存在，指定的数据。
- key {String} 要判断的键，点号是分隔符，用来分隔对象层次
- return {Bollean} 是否包含指定键值
demo
Data.has(key);//返回true或false
##get*
从Data中获取指定的键值。
- key {String} 要获取的键
- return {val} 返回与键值对应的数据，若键值的上游不存在，会返回undefined或null
demo
Data.get('a');//undefined
Data.get('a.b.c')//undefined
**注：**此处获取的是Data中数据的深拷贝，即get接口返回的数据是Data中对应数据的一份深拷贝。之所以牺牲性能，这样设计是因为深拷贝能避免很多难以预知的bug。
下面是深拷贝，浅拷贝和引用的区别：
//深拷贝
var a = Data.get('a');//若a为{b:{c:1}}
a.b.c= 2;//此处更改不会影像Data中的数据
Data.get('a.b.c')//此处输出1
//浅拷贝
var a = Data.get('a');//若a为{b:{c:1}}
a.b.c= 2;
Data.get('a.b.c')//此处输出2
//仅返回引用
var a = Data.get('a');//若a为{b:{c:1}}
a.b = 1;
Data.get('a.b')//此处输出1
##set*
向Data中放入数据。若已存在，则是扩展当前数据，不会重新赋值(对于数组或对象，对于其他类型值会覆盖)。
- key {String} 放入Data中数据的键值
- val {val} [可选] 放入Data中的数据
- return {Bollean} 是否添加成功
传入key + val 和 传入 {key: val}的方式等价，可以选择自己喜欢的方式，键值的方式更清晰，作者推荐前一种，记住只使用同一种方式会让事情变得简单。
demo
//传入值类型
D.set('a', 1);
D.get('a');//1
//传入引用类型
D.set('a', {b: 1});
D.get('a.b');//1
D.set('a.b.c', 1);
D.set('a', {b: {c: 1}}});//这两种功能一样
###key
key值是Data的基石，key是一个字符串，Data的key支持任何utf-8编码的字符，js支持的就可以
- 字母 abc
- 数字 123
- 特殊字符 _-+$;'"...
- 甚至是汉字 颜海镜
Data都可以完美支持，同时key还有类似对象属性的特性，a.b.c是获取a下的b下的c，其中.号是分隔符，可以想像成js中的对象（其实Data内部确实是按对象处理）。
D.set('a', {});
D.set('a.b', 1);
D.set('a.c', [1]);
D.set('a.1.1', 1);//此处会创建数组
`D.get('a')`的输出如下：
{
1: [1],
b:1,
c:[undefined ,1]
}
Data可以将传入的键，智能转换为对应的空间，支持对象和数组。
##sub*
sub方法是Data的核心方法，用来订阅消息，订阅指定键值的指定事件，在对应的值发生变化时，会得到通知（当传入对象和数组时，消息会下发到其子元素）。
- type {String} 订阅消息的类型 （可选值：set, add, update, delete 分别代表 设置，添加，更新，删除，其中set是通用类型，其他三个为细分类型，并且互斥）
- key {String} 订阅消息的键值
- callback {Function} 消息接受函数
- return {Number} 消息的同意id用于取消订阅事件用
demo
D.sub('set', 'a', function (e) {console.log(e)});
D.set('a', 1);//a值更新，会调用回调函数
###e
- type {String} 消息的类型
- key {String} 消息的建
- data {val} 设置的值
##unsub
取消订阅的消息。
- type {String} 取消订阅消息的类型 （可选值：set, add, update, delete 分别代表 设置，添加，更新，删除，其中set是通用类型，其他三个为细分类型，并且互斥）
- key {String} 取消订阅消息的键值
- id {Number} [可选] sub是返回的消息的id
- return {Bollean} 是否取消成功
若id为空则会删除所有对应键值和类型的所有事件。
demo
var id = D.sub('set', 'a', function (e) {console.log(e)});
D.set('a', 1);//a值更新，会调用回调函数
D.unsub('set', 'a', id);
D.set('a', 1);//不会在收到通知
##注意事项
由于Data设计之初希望支持跨平台，所以要支持ecmascript类型数据，Data希望放入的是数据，期望的是原生数据，支持 Number，Bollean，String，Object，null，undefined，Array。对于Object和Array会是其深拷贝值，并且会创造层级。
对于其他类型对象js都默认为值类型，如dom节点，仅简单赋值其引用，所以消息无法下发到dom的子元素上，但get接口可以取到其子元素。其他类型对象还包括：
- window
- document
- dom
- dom list
- node list
请不要将复杂对象和引用自身的对象放入Data中，会造成性能的严重下降，和不可预知的问题。复杂对象包括如下：
- jquery对象
建议放入原生数据，对于jquery对象可传入其查询字符串。
