作者：ITPUB论坛编辑： nancy 2008-02-27 00:00

【IT168技术文档】

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.

<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>
