print: function (country) {
console.log(this.name + ‘ is form ‘ + country);
}
};
var self = {
name: ‘yyy‘
};
var bindFn = angular.bind(self, obj.print, ‘China‘);

obj.print(‘American‘); //$ xxx is form American
bindFn(); //$ yyy is form China
返回值:拷贝的对象

var dst = {name: ‘xxx‘, country: ‘China‘};
var src = {name: ‘yyy‘, age: 10};
angular.extend(dst, src);
console.log(src); //$ Object {name: "yyy", age: 10}
console.log(dst); //$ Object {name: "yyy", country: "China", age: 10}
返回值:obj
var obj = {name: ‘xxx‘, country: ‘China‘};
angular.forEach(obj, function (value, key) {
console.log(key + ‘:‘ + value);
});
//$ name:xxx
//$ country:China
var array = [‘xxx‘, ‘yyy‘];
angular.forEach(array, function (item, index) {
console.log(index + ‘:‘ + item + ‘ form ‘ + this.country);
}, obj);
//$ 0:xxx form China
//$ 1:yyy form China
返回值:json对象
var json = angular.fromJson(‘{"name":"xxx","age":34}‘);
console.log(json); //$ Object {name: "xxx", age: 34}
返回值:字符串
angular.toJson({name:‘xxx‘});
//$ "{"name":"xxx"}"
angular.toJson({name:‘xxx‘},true);
//$ "{
//$ "name": "xxx"
//$ }"

//$ "{
//$ "name": "xxx"
//$ }"
返回值:第一个参数
