angular.foEach

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);
});
