请教关于ASP.NET的问题

想用JAVASCRIPT来判断FORM中的选项是否符合要求。只是程序在FIREFOX没问题，IE不行，JAVASCRIPT也执行了，就是每次都SUBMIT。

点这里看实例。那位能手帮帮忙？谢谢了。

应该没问题的。lz再检查一下自己的code吧。既然JAVASCRIPT也执行了，可以在js function最开始加个debugger，把IE的允许debug打开，逐步运行看哪里出问题了。

没有任何错误，只是当你不输入任何东西，然后就点击SUBMIT时，POP　UP　WINDOW打开，当CLICK　OK时，就SUBMIT了。

是否我的CODE　BEHIND的程序写的不对。

我把CODE贴在这。多谢了!

红字部分。只有返回没有相应操作吗？
