关于阮一峰js继承文章阅读笔记

//构造函数的继承
function Parent(name){
    this.name = name;
    this.action = function(){
        console.log(this.name)
    }
}
function Child(name){
    Parent.call(this,name)
}
var obj = new Child("tom")
obj.action()

//原型链继承之子类原型 = 父类实例
function Parent(name){
    this.name = name
    this.action = function(){
        console.log(this.name)
    }
}
Parent.prototype.say =function(){
    console.log("hello")
}
function Child(name){
}
Child.prototype = new Parent("jiangqi")
var obj = new Child()
obj.action()

//原型链继承之子类原型 = 父类原型
function Parent(name,say){
    this.name = name
    this.say = function(){
        console.log("hello")
    } 
}
Parent.prototype.see = function(){
    console.log("see")
}
function Child(){

}
Child.prototype = Parent.prototype
Child.prototype.constructor = Child;
var obj = new Child("jiangqi")
obj.see()
