// 例子1:-------------------------
|
|
// 创建一个父类
|
|

|
// 构造函数
|
|

// 声明类实例
|

//例子2:-------------------------
|
|
|
|
// 创建一个类,继承Person类,并重写getName
|
|
var Man = Class.create({
|
|
init:function(option) {
|
|
this._super(option);// 调用父类构造函数
|
|
this.age = option.age;
|
|

|
|
// 重写父类方法
|
|
,getName:function() {
|
|
// 调用父类的getName()
|
|
var name = this._super();
|
|
return '我重写了getName方法:{'+name+'}';
