我认为您可以使用文本框的Maxlength属性.
为什么要使用JavaScript?

I think you can use Maxlength property of textbox.
Why you want go for javascript?

嗨...

您提供的解决方案链接工作正常，但是当我在VS 2003中尝试相同的方法时，则无法正常工作.甚至我已经在该javascript中添加了警报消息，但是当我按下键时却没有得到警报...实际上表明该事件甚至没有被触发.

您可以为此提供任何解决方案吗?

hi...

The solution link you have provided is working fine but when i try the same in VS 2003 its not working. Even i have added a alert message in that javascript but i didnt get the alert when i press the key... which actually tell that the event is not even fired.
