复制代码 代码如下:

//以构造函数方式添加私有属性和方法

function Person(name, age, address) {

this.name = name;

this.age = age;

this.address = address;

}

//以原型方式添加公有属性、方法

Person.prototype = {

constructor: Person,

showName: function () {

alert(this.name + this.age + this.address);

}

}

//使用

var person = new Person("zhangsan", 22, "中国北京！");

person.showName();
