UMVCL2——不使用MVC思想制作UI逻辑

不使用MVC的UI逻辑制作实例

假设我们有一个主面板，它的各个UI控件需要的效果如下

有一个选角面板，它的各个UI控件需要的效果如下

两面板的代码逻辑如下：

MainPanel

这个脚本实现的功能如下：

  1. 面板的显隐（加载并装载自己）
  2. 控件监听
  3. 角色按钮显示RolePanel
  4. 读取并更新数据

不使用MVC带来的问题

可以发现，不使用MVC思想时：
数据读取显示，数据保存，执行逻辑，控件监听，控件获取，面板显隐，
全部分别糅合在几个UI脚本里，它们都有各自的实现，
同时同一批数据控制分散在不同的UI脚本内。
显然随着项目的日益扩大，不加以改善关系会越来越混乱，
这不利于我们对代码的维护

接下来让我们试试用MVC再实现相同的功能
