用得着那么复杂么？

<body>
<div id="txt2"></div>
<script language="javascript">
var timeLeft = 60;
go();
function go() {
if (timeLeft > 0) {
document.getElementById('txt2').innerText = timeLeft;
timeLeft--;
window.setTimeout(go, 1000);
}
}
</script>
</body>

这个例子就是解决输入多少时间，从多少时间起倒计时，看看是不是你要得效果！
1.asp:
<body>
<form action="time.asp" method="post">
<p>考试时间：
<input type="text" name="examtime">
分</p>
<p>
<input type="submit" name="Submit" value="开始考试">
</p>
</form>
</body>
time.asp:
<%@ Language=VBScript %>
<HTML>
<HEAD>
<META NAME="GENERATOR" Content="Microsoft Visual Studio 6.0">

</HEAD>

<BODY onload="setTimeEnd();">
<script>
if(getCookie("times")==null||getCookie("times").split(":")[2].toString()=="NaN")
{

var endminutes=<%=(request.form("examtime"))%>*60;
}
else
{
var endminutes=parseInt(getCookie("times").split(":")[1])*60+parseInt(getCookie("times").split(":")[2]);
}
var betweendays=0;
function setTimeEnd()
{
var hour=0;
endminutes= endminutes - 1;
hour=parseInt(endminutes / 3600);
minutes=parseInt((endminutes- hour*3600)/60);
second= (endminutes- hour*3600- minutes*60)
hour = hour.toString();
if (hour.length < 2)
hour = "0" + hour;
minutes=minutes.toString()
if (minutes.length<2)
minutes="0"+minutes;
if (second<10)
second="0"+second;

var temp=hour+":"+minutes + ":" + second;
document.all.countdown.innerText=temp
SetCookie("times",temp);
if (endminutes==0)
{
alert("考试时间到！");
return;
}
setTimeout("setTimeEnd()",1000);
}

function SetCookie(name,value)
{
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) + ((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) + ((domain == null) ? "" : ("; domain=" + domain)) + ((secure == true) ? "; secure" : "");
}
function DeleteCookie(name)
{
var exp = new Date();
exp.setTime (exp.getTime() - 1);
var cval = GetCookie (name);
document.cookie = name + "=" + cval + ";expires=" + exp.toGMTString();
}
function getCookie(cookieName)
{
var cookieString = document.cookie;
var start = cookieString.indexOf(cookieName + '=');
// 加上等号的原因是避免在某些 Cookie 的值里有
// 与 cookieName 一样的字符串。
if (start == -1) // 找不到
return null;
start += cookieName.length + 1;
var end = cookieString.indexOf(';', start);
if (end == -1) return unescape(cookieString.substring(start));
return unescape(cookieString.substring(start, end));
}

</script>
