mootools1.5.1使用笔记：类的创建，继承，为现有类增加新方法

window.addEvent('domready',function(){
        /*
            新建一个Person的类，类上有 name属性和sayHello方法；
        */
        var Person= new Class({
            initialize: function(name){
                this.name = name;
            },
            sayHello:function(){
                console.log('hello,my name is '+this.name);
            }

        });

        //新建一个Sperman类，继承Person上的属性和方法
        var Sperman=new Class({
            Extends:Person,
            initialize:function(name,age){
                this.parent(name);
                this.age=age;
            },
        });
        //给Dog扩展新方法 sayWang
        Sperman.implement({
            sayAll:function(){
                console.log(this.name+' is '+this.age+' years old...');
            }
        });
        var Sperman=new Sperman('ollie',27);
        Sperman.sayHello();//consolo.log   hello,my name is ollie

        Sperman.sayAll();//console.log  ollie is 27 years old...
    });
