javascrpit的问题，很简单，希望你能回答

这个问题是很简单的，主要是因为没人告诉你的原因吧～～
asp.net中没有onchlick事件需要你注册一下～～
不要在html中写onchlick。这个是需要在后台注册的。你只需要在前台。写一段脚本。就是你要执行的javascrpit。
在后台注册一下就行。
名.seta******.add（控件名，javascrpit函数）；
就是这样就行了～～

好多高手..

给form命名,可以存在多form的

Response.Write("");
这段代码就是在客户端写入
""
所以每次刷新都会执行这一句,所以就会出来一个警告框,除非你给出这个提示后是转到其他页面,才能用这种方式来写
你的第二种写法:
onchick＝“return ff（）”

这种写法应该是可以的,你可以试一下在ff()里把if的条件判断先去掉,应该是可以的,正常来说是你的if条件判断不成立导致的.

有其他更好的解决方案,仔细想一想.

是

注意，你不能用messagebox 只能有js来写。
