javascript实现创建对象的三种方法

//工厂模式创建对象
function CreatePerson(name, age) {
var c = new Object();
c.name = name;
c.age = age;
c.SayName = function () {
this.name;
}
return c;
}
//构造函数方式
function CreatePerson(name, age) {

this.name = name;
this.age = age;
this.SayName = function () {
this.name;
}
}
//原型模式
function Human(name, age) {
this.name = name;
this.age = age;
}
Human.prototype.sayName = function () {
alert(this.name);
}
