js-创建对象的三种方法

1，利用字面量创建对象--调用方法时--对象名.方法名()

  var object = {
            name:"张三",
            age:18,
            sex:"女",
            action:function(){
                console.log("hi~~")
            }
        }

        console.log(object.name);
        console.log(object.age);
        object.action()

2，利用new Object创建对象

var people = new Object()
        people.name = "鸣人"
        people.sex="男"
        people.age = 19
        people.skill = function(){
            console.log("影分身术")
        }
        console.log(people)

3、利用构造函数创建对象-----这个过程也叫对象的实例化---可以封装函数以供取用

function 构造函数名() {

        this.属性 = 值

        this.方法 = function() { }

}

new 构造函数名()

 function Star(uname,age,sex){
            this.name = uname
            this.age= age
            this.sex = sex
            this.sing = function(sang){
                console.log(sang)
            }
        }
        var ldh = new Star("刘德华",18,"男")
        console.log(ldh.name);
        ldh.sing("冰雨")
        var zxy = new Star("张学友",19,"男")
        console.log(ldh.age);
        ldh.sing("吻别")
