// JS类的创建,继承
//-------------------------
// 例子1:-------------------------
// 创建一个父类
var Person = Class.create({
// 构造函数
init:function(option){
this.name = option.name;
}
,getName:function() {
return this.name;
}
});
// 声明类实例
var Jim = new Person({name:'Jim'});
console.log('Jim name:' + Jim.getName())
//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();
