创建对象三种方式
1 字面量的方式
var per1={ name:"沐风", age:20, sex:"男", eat:function () { console.log("吃"); }, readBook:function () { console.log(""); } };
2 调用系统的构造函数
var per2=new Object(); per2.name="沐风"; per2.age=30; per2.sex="男"; per2.eat=function () { console.log("吃"); }; per2.play=function () { console.log("玩"); };
3 自定义构造函数方式
function Person(name,age,sex) { this.name=name; this.age=age; this.sex=sex; this.play=function () { console.log("天天打游戏"); }; } var per=new Person("沐风",18,"男"); console.log(per instanceof Person);
