倒计时载入页面

脚本说明：
第一步:把如下代码加入<head>区域中:
<META HTTP-EQUIV="REFRESH" CONTENT="11; URL=14.htm">
第二步:把<body>中加入如下代码：
<META HTTP-EQUIV="REFRESH" CONTENT="11; URL=14.htm">

<script language="JavaScript">

startday = new Date();
clockStart = startday.getTime();

function initStopwatch()
{
var myTime = new Date();
     var timeNow = myTime.getTime();
     var timeDiff = timeNow - clockStart;
     this.diffSecs = timeDiff/1000;
     return(this.diffSecs);
}

function getSecs()
{
     var mySecs = initStopwatch();
     var mySecs1 = ""+mySecs;
     mySecs1= mySecs1.substring(0,mySecs1.indexOf(".")) + " secs.";
     document.form1.timespent.value = mySecs1
     window.setTimeout('getSecs()',1000);
}
</script>
<center>
This page will change in 10 seconds:
<form name=form1><input size=9 name=timespent></form>
</center>
第三步：把<body>中内容改为：
<body bgcolor="#F7F7FF" onLoad="window.setTimeout('getSecs()',1)">
