javascript学习笔记（五）原型和原型链详解_基础知识

var Jobs = new Person("Jobs");
Jobs.company = "Apple";//设置自己的company属性，掩盖了原型的company属性
Jobs.SayHello = function()
{
alert("Hi,"+this.name + " like " + this.company);
};
Jobs.SayHello();//自己覆盖的属性和方法，输出"Hi,Jobs like Apple"
BillGates.SayHello();//Jobs的覆盖没有影响原型，BillGates还是照样输出
