有没有那位有jsp的啊？？最后是带数据库的！！谢谢了啊！！
阿信的站点上好象有，是用JavaScript做的
其实也没有什么,就是三个表关联一下.在数据库取出数据后放到客户段(javascript)的叔祖里,用 onchange事件去改变就可以了!
我的就是jsp的啊~！·  小改一下就可以了  我以前的同事叫缪红
数据库写在bean里面了  在前面调用一下就可以了
AppletHide是不是bean啊？？好象少东西
AppletHide是一个用于前后端通讯的一个applet，用它通过http通道把请求发送到后端。你用一个bean替换他就可以了，在这里它的功能就是从数据库里面把相关联的数据取道前面来。
