Angular.forEach用法

1.针对对象循环(key,value)

官方示例：

var values = {name: 'misko', gender: 'male'};var log = [];angular.forEach(values, function(value, key) {  this.push(key + ': ' + value);}, log);expect(log).toEqual(['name: misko', 'gender: male']);

2.针对对象数组(key,value)

非官方示例：

var objs =[{a:1},{a:2}];angular.forEach(objs, function(data,index,array){//data等价于array[index]console.log(data.a+'='+array[index].a);});

3.针对对象数组（data）

非官方示例：

var objs =[{a:1},{a:2}];angular.forEach(objs, function(data){console.log(data.a);});
