//js模拟类的创建以及继承
//第一步:创建父类
function Parent(name){
this.name = name;
}
//给父类添加属性方法
Parent.prototype.age = 18;
//var p1 = new Parent();
//第二步:创建子类
function Child(){
Parent.call(this,"asdfasfd");
}
//第三步:确定继承的关系
Child.prototype = Object.create(Parent.prototype);
Child.prototype.stuno = "2000";
//第四步:改造构造器(不是很重要)
//改变了某个构造器的原型之后,紧接着的代码一定是改构造器
Child.prototype.constructor = Child;
/* Object.create的实现
function create(proto){
function F(){}
F.prototype = proto;
var temp = new F();
return temp;
}
*/
//var o = new Parent();
//o instanceof Object;
