标题: ASP模拟MVC模式编程

内容: 大家都知道JAVA里最流行的是MVC模型的编程方式，如果你不知道MVC的概念，可以去网上搜索下，应该会马上找到N多资料。PHP5推出之后，也开始使用MVC模式开发，看来MVC确实有很大的吸引力！
我在平时开发ASP项目的时候，也借鉴了JAVA的这个开发模式，虽然实现的不是很好，但也使代码结构清晰了不少，大大方便了美工修改程序！
下面是我的代码，具体说明看注释。
程序主要实现是后台管理员的操作：添加，删除，修改
分两个程序，adminusers_class.asp，adminusers_gl.asp
相当于JAVA力一个servlet，一个bean！所以没有完全的实现MVC，只是模拟了一下！
adminusers_class.asp代码如下：

以上程序写的不是很好，但结构还是比较清晰的，在adminusers_gl.asp中分别对action进行判断，去调用类中的不同方法，在下面页面部分，尽量使ASP代码减少，这样美工就能很轻松的修改程序界面了！
如果你觉得程序写的不好，请不要见笑，欢迎大家和我交流。
