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=/(/[email protected]/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>
<body>
