iframe问题

Question

我有一个form主要有三个iframe,上面有一个导航：比如说：JAVA，.net，C++。点击这三个链接，就进入了下面一个树型：就好像是CSDN里面的树型技术分类J2SE / 基础类 ,J2SE / 扩展类 ,GUI 设计点击 J2SE / 基础类，这个后，上面的导航栏JAVA链接不能刷新，怎么实现，谢谢大家了。

Answer 1

处理select的onchange事件，写个function，在这个function里取得option的value值，然后提交下一个tree所在的iframe中的form，并把那个value值传过去，检索出相应的值。
下一层同上
