html页面的倒计时代码。。。。急求！！！！,第1张

<body>

<div id="timer"></div>

<script type="text/javascript" language="javascript">

var endDate=new Date(2010,11,11,17,05,40)//年月日时分秒，月要减去1

(function daoJiShi()

{

var now=new Date()

var oft=Math.round((endDate-now)/1000)

var ofd=parseInt(oft/3600/24)

var ofh=parseInt((oft%(3600*24))/3600)

var ofm=parseInt((oft%3600)/60)

var ofs=oft%60

document.getElementById('timer').innerHTML='还有 '+ofd+' 天 ' +ofh+ ' 小时 ' +ofm+ ' 分钟 ' +ofs+ ' 秒'

if(ofs<0){document.getElementById('timer').innerHTML='倒计时结束！'return}

setTimeout('daoJiShi()',1000)

}())

</script>

</body>

<br>倒计时已结束<br>

<span id="span_dt_dt" style='border:1px solid blackbackground-color:#FFFFFF' ></span>

<SCRIPT language=javascript>

<!--

//document.write("")

function show_student163_time(){

window.setTimeout("show_student163_time()", 1000)

BirthDay=new Date("00-00-0000")//改成你的计时日期

today=new Date()

timeold=(BirthDay.getTime()-today.getTime())

sectimeold=timeold/1000

secondsold=Math.floor(sectimeold)

msPerDay=24*60*60*1000

e_daysold=timeold/msPerDay

daysold=Math.floor(e_daysold)

e_hrsold=(e_daysold-daysold)*24

hrsold=Math.floor(e_hrsold)

e_minsold=(e_hrsold-hrsold)*60

minsold=Math.floor((e_hrsold-hrsold)*60)

seconds=Math.floor((e_minsold-minsold)*60)

span_dt_dt.innerHTML=daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒"

}

show_student163_time()

//-->

</SCRIPT>

修改成需要的时间段，直接嵌入就可以了~~~祝你愉快！
