1、object 类型构造函数
var obj1 = new Object();
var arr = new Array();
var str = new String();
//添加属性
obj1.name = "zhangsan";
// 添加方法
obj1.play = function(){
console.log(this.name + '在play');
}
2、字面量定义
var obj2 = {}
obj2.name = 'zhangsan'
obj2.age = 22 ;
obj2['name'] = 'lisi'
obj2['age'] = 55;
// 嵌套字面量
var obj3 = {
name:'wangwu',
age:22,
other:{
hobby:['足球','篮球'],
sex:'男'
}
}
3、工厂方法定义
function createObj(name,age){
var obj = new Object();
obj.name = name;
obj.age = age;
obj.eat = function(){};
return obj;
}
var o1 = new createObj('zhangsan',20);
var o2 = new createObj('lisi',24);
4、构造函数
function CreateObj(name,age){
this.name = name;
this.age = age;
this.play = function(){
console.log(this.name + 'is playing');
}
}
var c1 = new CreateObj('lili',20)
var c2 = new CreateObj('lucy',23)
5、Object.create()
var objc = {
name:'wangergou',
age:24
}
var objc1 = Object.create(objc);
console.log(objc1.__proto__);// objc1.__proto__ === objc
