csdn高手们 帮我看看 啊 嘿嘿！
我用正规表达式校验密码和重复密码遇到问题了，我是用控件校验，现在还没有办法解决！
<asp:Content ID= "Content2 " ContentPlaceHolderID= "MainContent " Runat= "Server ">
<script language= "javascript " type = "text/javascript ">
function isPasswd(sTextId) {
alert(sTextId);
var s =document.all. "+ TextBox2.ClientID +@ ".value;
// s = document.getElementById( "TextBox2 ");
var patrn=/^(\w){6,20}$/;
if (!patrn.exec(s))
{
return false;
}
else
{
return true;
}
}
</script>

[解决办法]
没有试过JS加验证控件一起用。
------解决方案--------------------
为什么要用JS，正则表达式直接写在html里不行啊？
