<script language="javascript">
var secs = 3; //倒計時的秒數(shù) 
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('ShowDiv').innerHTML = '將在'+num+'秒后自動跳轉(zhuǎn)到主頁' ;

<script type="text/javascript">

    function delayURL() { 
        var delay = document.getElementById("time").innerHTML;
 var t = setTimeout("delayURL()", 1000);
        if (delay > 0) {
            delay--;
            document.getElementById("time").innerHTML = delay;
        } else {
