March 25,2004

运行环境:Win2000 Advance Server+IIS5.0+NGWS SDK(80M的).
其中验证email地址的函数用的是廖兄精华区中的代码.
<%@ Page Language="C#" %>

<html>
<script language="javascript">
function ClientValidateEmail(source, value)
{
  var strr;
  re=/(w+@w+.w+)(.{0,1}w*)(.{0,1}w*)/i;
  re.exec(value);
  if (RegExp.$3!=""&&RegExp.$3!="."&&RegExp.$2!=".") strr=RegExp.$1+RegExp.$2+RegExp.$3
  else
if (RegExp.$2!=""&&RegExp.$2!=".") strr=RegExp.$1+RegExp.$2
else  strr=RegExp.$1
  if (strr!=value)
return false;
  else
return true;
}
</script>
