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); });
