第一种：精确到秒的javascript倒计时代码

HTML代码:

<form name="form1">
<div align="center" align="center">
<center>离2010年还有:<br>
<input type="textarea" name="left" size="35" style="text-align: center">
</center>
</div>
</form>
<script LANGUAGE="javascript">
startclock()
var timerID = null;
var timerRunning = false;
function showtime() {
Today = new Date();
var NowHour = Today.getHours();
var NowMinute = Today.getMinutes();
var NowMonth = Today.getMonth();
var NowDate = Today.getDate();
var NowYear = Today.getYear();
var NowSecond = Today.getSeconds();
if (NowYear <2000)
NowYear=1900+NowYear;
Today = null;
Hourleft = 23 - NowHour
Minuteleft = 59 - NowMinute
Secondleft = 59 - NowSecond
Yearleft = 2009 - NowYear
Monthleft = 12 - NowMonth - 1
Dateleft = 31 - NowDate
if (Secondleft<0)
{
Secondleft=60+Secondleft;
Minuteleft=Minuteleft-1;
}
if (Minuteleft<0)
{
Minuteleft=60+Minuteleft;
Hourleft=Hourleft-1;
}
if (Hourleft<0)
{
Hourleft=24+Hourleft;
Dateleft=Dateleft-1;
}
if (Dateleft<0)
{
Dateleft=31+Dateleft;
Monthleft=Monthleft-1;
}
if (Monthleft<0)
{
Monthleft=12+Monthleft;
Yearleft=Yearleft-1;
}
Temp=Yearleft+'年, '+Monthleft+'月, '+Dateleft+'天, '+Hourleft+'小时, '+Minuteleft+'分, '+Secondleft+'秒'
document.form1.left.value=Temp;
timerID = setTimeout("showtime()",1000);
timerRunning = true;
}
var timerID = null;
var timerRunning = false;
function stopclock () {
if(timerRunning)
clearTimeout(timerID);
timerRunning = false;
}
function startclock () {
stopclock();
showtime();
}
// -->
</script>

第二种：某某运动会

HTML代码:

<script language="JavaScript">

</script>

<body onload=DigitalTime1()>
<div id= LiveClock1></div>

</body>

第三种：小时倒计时

HTML代码:
<SCRIPT LANGUAGE="JavaScript">

</SCRIPT>
<div , nextelapse);
}
</script>

附加一个完整的倒计时和时间复制即可使用运行的结果分别是：
