页面刷新有数据，点击里面的选项就空白，无数据了。

悬赏园豆：40 [待解决问题]

代码主要写在jsp文件里。刷新界面后是我需要的效果，但是点击里面的选项时，数据就没有了，之后不管怎么点，一样没数据。请问怎么解决？

其实你可以说得更抽象一点的，比如象这样，

我有一个问题不能解决，你们谁能解决。

这个问题是跟编程有关的。

我初学者，不知道该怎么说，就说了结果。只想知道个大体思路

@lrz8169: 初学者？

我说的是语文，你学了几年了，

现在小学就开始教JSP了吗？这个我倒是不知道...

你要这样问，能答上来的只有天桥下摆摊的...

不要问现象，出现问题了，要能够自己定位。你刷新有数据，而点击没有数据。你要看看，点击的时候，有没有请求发送出去。装个fiddler自己监控一下。估计是js错了。
