AngularJS 對象處理

對象復(fù)制： angular.copy()

var a = {'x': '123'};
var b = angular.copy(a);
a.x = '456';
console.log(b);

對象聚合： angular.extend()

var a = {'x': '123'};
var b = {'xx': '456'};
angular.extend(b, a);
console.log(b);

空函數(shù)： angular.noop()

大小寫轉(zhuǎn)換： angular.lowercase() 和 angular.uppercase()

JSON轉(zhuǎn)換： angular.fromJson() 和 angular.toJson()

遍歷： angular.forEach() ，支持列表和對象：

var l = {a: '1', b: '2'};
angular.forEach(l, function(v, k){console.log(k + ': ' + v)});

var l = ['a', 'b', 'c'];
angular.forEach(l, function(v, i, o){console.log(v)});

var context = {'t': 'xx'};
angular.forEach(l, function(v, i, o){console.log(this.t)}, context);
