angular.forEach
描述:
循环对obj对象的每个元素调用iterator, obj对象可以是一个Object或一个Array. Iterator函数调用方法: iterator(value, key, obj), 其中obj是被迭代对象，key是obj的property key或者是数组的index，value就是相应的值啦. (此函数不能够迭代继承的属性.)
使用方法:
angular.forEach(obj, iterator, [context])
参数详解:
| obj | ObjectArray | 被迭代的对象. |
| iterator | Function | 迭代函数 |
| context
(optional)
|
Object | Object to become context ( |
返回值:
