样式自己调整一下,功能可以实现
HTML code

<HTML>
<HEAD>
<TITLE><%=homepage_title%>--管理中心-用户登陆</TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">

<script language="JavaScript">
<!--
function window_onload() {
    document.mail.username.focus();
}
function cancel()
{
    mail.reset();
    document.getElementById("txtHint").innerHTML="";
}

function IsValid()
{
    if (document.mail.username.value=="")
    {
        document.getElementById("txtHint").innerHTML="用户名不能为空";
        document.mail.username.focus();
        return false;
    }
    if (document.mail.password.value=="")
    {
        document.getElementById("txtHint").innerHTML="密码不能为空";
        document.mail.password.focus();
        return false;
    }
    
}
//-->
</script>

<style type="text/css">
<!--

</HEAD>

<BODY  topMargin=0 leftmargin="0" onLoad="return window_onload()">
