//考查js继承的几种方式
//如下使用寄生式组合继承
function Human(name) {
this.name = name
this.kingdom = 'animal'
this.color = ['yellow', 'white', 'brown', 'black']
}
function Chinese(name,age) {
Human.call(this,name)
this.age = age
this.color = 'yellow'
}
// 补全代码
Human.prototype.getName = function (){
returnthis.name
}
//Chinese.prototype = new Human()
Chinese.prototype = Object.create(Human.prototype)
Chinese.prototype.getAge = function(){
returnthis.age
}
我现在也只有一个保底
太难了
