上載者:User

例:===========Logout.aspx 頁============================

 

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script language='javascript' type='text/javascript'>
var secs =5; //倒計時的秒數
var URL;
function Load(url) {
URL = url;
for(var i=secs;i>=0;i--)
{
window.setTimeout('doUpdate(' + i + ')', (secs-i) * 1000);
}
}
function doUpdate(num)
{
document.getElementById('msg').innerHTML = '您已經退出登入,將在' + num + '秒後返回';
if(num == 0) { window.location=URL; }
}
</script>
</head>
<body>
<form id="form1" runat="server">

<div id="msg" style="margin:20px auto;"></div>

<script language='javascript' type='text/javascript'>
Load("<% = GetReturnUrl() %>");  

<!---這裡調用的asp.net方法,也可以在這裡直接寫出url地址-->
</script>


</form>
</body>
</html>
