最近在研究javascript,发现这个语言很有趣.
<html>
<head>
<script language="JavaScript">
//圣诞节的倒计时
var EndTime=new Date("December 25,2008");
function GetRTime()
{
var NowTime = new Date();
var nMS =EndTime - NowTime.getTime();
var nH=Math.floor(nMS/(1000*60*60)) % 24;
var nM=Math.floor(nMS/(1000*60)) % 60;
var nS=Math.floor(nMS/1000) % 60;
var nD=Math.floor(nMS/(1000*60*60*24));
document.getElementById("RemainD").innerHTML=nD;
document.getElementById("RemainH").innerHTML=nH;
document.getElementById("RemainM").innerHTML=nM;
document.getElementById("RemainS").innerHTML=nS;
if(nMS>5*59*1000 && nMS<=5*60*1000)
{
alert("还有最后五分钟！");
}
if(nMS>1000)
{
setTimeout("GetRTime()",1000);
}
}
window.onload=GetRTime;
