※ 引述《hpuser (HpUser)》之铭言：
: 请问各位先进:
: 舞台上有一个自订的button，移过去会变大，移出去会变小,
: 如要实作puremvc，就要 把这个button注册给一个mediator,
: 由这个mediator来控制变大变小的效果.
: 可是因需要，场景上会动态增加多个button，甚至更多，
: 难道要一个一个注册给mediator吗?
: 有没有可能 我只要注册这个自订button类别给mediator，
: 一次就可以了,或是更方便的作法?
: 看教学,view物件似乎都是舞台上已经存在的实体居多，
: 没看过注册类别给mediator.
: 谢谢

1F：→ ben0209:这篇，开始pureMVC之前只有btns container， 09/01 11:04
2F：→ ben0209:开始 pureMVC 之後，再於 container 的 mediator 中， 09/01 11:04
3F：→ ben0209:动态建立 btn * 20，并注册对应的 mediator 09/01 11:05
4F：推 hpuser:感谢Ben大提供两种不同方法的详细教学，小弟受教了 09/01 11:52
