js中对象继承的冒充方法

function Parent(name){
    this.name = name;
    this.sayName  = function(){
       console.log(this.name);
   }
}

function Son(name,password){
  this.method = Parent;
  this.method(name);
  this.show = function(){
       console.log(this.name+‘ : ‘+this.password)
   }
  delete this.method;
}

var son1 = new Son(‘zhangsan‘,‘123456‘);
son1.show();

这种继承方式和原型链继承不一样，

这个是偷换了this的指向
