第一种：精确到秒的javascript倒计时代码
HTML代码:
复制代码 代码如下:
<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)

}
function startclock () {
stopclock();
showtime();
}
