就像http://register.9you.com/regist1.jsp中，当我打开该注册页面的时候用户名输入框后提示：用户名可使用数字、字母，长度为6-12，当我输入汉字的时候直接提示：用户名只可使用数字、字母

而当我输入数字或字母位数少于6位或者位数大于12位的石油直接提示：用户名长度只能为6-12位

以及正则表达式在Javascript脚本中如何应用：

我想将注册页面的用户名限制为6-12的数字或字母，在Javascript脚本中中如何应用\w{6,12}？？？

有谁可以将代码帖出来让大家分享下！！！

希望能够得到帮助！

没人会用ASP写注册页面的直接提示功能吗？我相信这里有的是人才，只要你们济点时间出来帮帮我嘛

你这些都是一般的注册页面添加代码啊？有没有那种如楼主说的那种？

LZ是来要代码的还是讨论学习的???
