对象处理


12.2. 对象处理

对象复制: angular.copy()

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

对象聚合: angular.extend()

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

空函数: angular.noop()

大小写转换: angular.lowercase()angular.uppercase()

JSON转换: angular.fromJson()angular.toJson()

遍历: angular.forEach() ,支持列表和对象:

  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);
