浅谈JS继承

1,属性继承

继承:子级继承父级的一些属性或者方法

call apply:专门用来实现属性的继承

function Person(name,age,sex){
this.name = name;
this.age = age;
this.sex = sex;
}

Person.prototype.eat = function(){
console.log("正在吃饭")
}

Person.prototype.sleep = function(){
console.log("正在睡觉")
}

function Man(larynx,beard,name,age,sex,){
Person.call(this,name,age,sex)

this.larynx = larynx;
this.beard = beard;

}

Man.prototype.work = function(){
console.log('111')
}

var songlei = new Man(10,20);
console.log(songlei);
