setTimeout(“clock()”,1000)}/script 上面的是JS部分的。 下面是HTML部分的。div class=”mains”

div class=”djs”

div id=”dd”/div

div id=”tsfm”天/div

div id=”hh”/div

div id=”tsfm”時/div

div id=”mm”/div

div id=”tsfm”分/div

div id=”ss”/div

div id=”tsfm”秒/div

/div 我上面的JS部分的數字全部是用的圖片格式顯示倒計時數字的哈，你也可以自己改成數字。 好了，上面的代碼全部是我之前給客戶寫的一個春節倒計時賀卡的程序頁面，純原創，並且一直在用，所以是沒有任何問題的，你自己應該懂一些技術吧，所以上面的代碼你應該看的懂，很簡單的。 就不要再追問了，自己多下下功夫研究下，因為最近比較忙，不見得有時間回復，見諒。記得給我分哈，要升級這個號的級別，以後好推廣用，謝謝了。

javascript倒計時代碼

我給你做了一個，你看行不行？

js代碼：fun.js

var timmerID = null;

function time() {

var time = document.getElementById(“now”);

var left = document.getElementById(“left”);

var t = time.value.split(“:”);

var hour = parseInt(t[0]);

var min = parseInt(t[1]);

min=min+1;

if(min==60){

hour=hour+1;

min=0;

if(hour==24){

hour=0;

}

}

time.value=hour+”:”+min;

left.value = left.value-1;

if(left.value==0){

mystop();

alert(“時間已到！”);

}

}

function mystart() {

var left = document.getElementById(“left”);

left.value=”40″;

timmerID = window.setInterval(“time()”, 1000*60);

}

function mystop() {

window.clearInterval(timmerID);

}

html頁面：

!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”

html

head

titletime.html/title

script type=”text/javascript” src=”fun.js”/script

/head

body

時間起點：input type=”text” name=”now” id=”now” value=”0:0″/input type=”button” value=”開始” onclick=”mystart();”br

剩餘時間：input type=”text” name=”left” id=”left” value=”40″ disabled=”disabled”/分鐘br

/body

/html

補充：這個javascript放在一個文件叫fun.js,在html頁面中要引用此文件，如：script type=”text/javascript” src=”fun.js”/script ，注意不要把路徑弄錯了，src後面的路徑按照實際的來，如果兩個文件在一個目錄下，就是如上這樣引用，當然也可以直接把全部的js內容放在html文件的頭部，如：script type=”text/javascript”

JS 倒計時實現代碼(時、分，秒)

JS實現倒計時(時、分，秒)

var

{

var

now

=

new

Date();

var

endDate

=

new

Date(year,

month-1,

day);

var

leftTime=endDate.getTime()-now.getTime();

var

leftsecond

=

parseInt(leftTime/1000);

//var

day1=parseInt(leftsecond/(24*60*60*6));

var

day1=Math.floor(leftsecond/(60*60*24));

var

hour=Math.floor((leftsecond-day1*24*60*60)/3600);

var

minute=Math.floor((leftsecond-day1*24*60*60-hour*3600)/60);

var

second=Math.floor(leftsecond-day1*24*60*60-hour*3600-minute*60);

var

“腳本之家提示距離”+year+”年”+month+”月”+day+”日還有：”+day1+”天”+hour+”小時”+minute+”分”+second+”秒”;
