本文实例为大家分享了JS倒计时展示的具体代码,供大家参考,具体内容如下
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:
<!--倒计时Javascript begin--> <script language="JavaScript"> <!-- function DigitalTime1() { var deadline= new Date("08/13/2007") //开幕倒计时 var symbol="8月13日" var now = new Date() var diff = -480 - now.getTimezoneOffset() //是北京时间和当地时间的时间差 var leave = (deadline.getTime() - now.getTime()) + diff*60000 var day = Math.floor(leave / (1000 * 60 * 60 * 24)) var hour = Math.floor(leave / (1000*3600)) - (day * 24) var minute = Math.floor(leave / (1000*60)) - (day * 24 *60) - (hour * 60) var second = Math.floor(leave / (1000)) - (day * 24 *60*60) - (hour * 60 * 60) - (minute*60) var deadline_2= new Date("08/13/2004") //开幕后计时 var symbol_2="8月13日" var now_2 = new Date() var diff_2 = -480 - now.getTimezoneOffset() //是北京时间和当地时间的时间差 var leave_2 = (now_2.getTime() - deadline_2.getTime()) + diff_2*60000 var day_2 = Math.floor(leave_2 / (1000 * 60 * 60 * 24)) var hour_2 = Math.floor(leave_2 / (1000*3600)) - (day_2 * 24) var minute_2 = Math.floor(leave_2 / (1000*60)) - (day_2 * 24 *60) - (hour_2 * 60) var second_2 = Math.floor(leave_2 / (1000)) - (day_2 * 24 *60*60) - (hour_2 * 60 * 60) - (minute_2*60) day=day+1; day_2=day_2+1; if (day>0) //还未开幕 { //LiveClock1.innerHTML = "现在"+symbol+"天" LiveClock1.innerHTML = "<font setTimeout("DigitalTime1()",1000) } if (day<0) //已经开幕 { //LiveClock1.innerHTML = "现在离"+symbol+"还有"+day+"天"+hour+"小时"+minute+"分"+second +"秒" LiveClock1.innerHTML = "<font setTimeout("DigitalTime1()",1000) } if (day==0) //正在开幕 { //LiveClock1.innerHTML = "现在"+symbol+"天" LiveClock1.innerHTML = "<font setTimeout("DigitalTime1()",1000) } if (day<0 & day_2>19) //某某运动会结束 { //LiveClock1.innerHTML = "现在离"+symbol+"还有"+day+"天"+hour+"小时"+minute+"分"+second +"秒" LiveClock1.innerHTML = "<font setTimeout("DigitalTime1()",1000) } } // --> </script> <!--倒计时Javascript end--> <body onload=DigitalTime1()> <div id= LiveClock1></div> </body>
第三种:小时倒计时
HTML代码:
<SCRIPT LANGUAGE="JavaScript"> <!-- var maxtime = 60*60 //一个小时,按秒计算,自己调整! function CountDown(){ if(maxtime>=0){ minutes = Math.floor(maxtime/60); seconds = Math.floor(maxtime%60); msg = "距离结束还有"+minutes+"分"+seconds+"秒"; document.all["timer"].innerHTML=msg; if(maxtime == 5*60) alert('注意,还有5分钟!'); --maxtime; } else{ clearInterval(timer); alert("时间到,结束!"); } } timer = setInterval("CountDown()",1000); //--> </SCRIPT> <div id="timer" style="color:red"></div>
第四种:最简倒计时
HTML代码:
<Script Language="JavaScript"> <!-- Begin var timedate= new Date("January 14,2006"); var times="研究生考试"; var now = new Date(); var date = timedate.getTime() - now.getTime(); var time = Math.floor(date / (1000 * 60 * 60 * 24)); if (time >= 0) ; document.write("<li><font color=#DEDBDE>现在离2006年"+times+"还有: <font color=#ffffff><b>"+time +"</b></font> 天</font></li>"); // End --> </Script>
第五种:最简倒计时二
HTML代码:
<script language="JavaScript" type="text/javascript"> function djs(){ var urodz= new Date("11/12/2008"); var now = new Date(); var num var ile = urodz.getTime() - now.getTime(); var dni = Math.floor(ile / (1000 * 60 * 60 * 24)); if (dni >1) num=dni+1 else if (dni == 1) num=2 else if (dni == 0) num=1 else num=0 document.write(num) } </script>
距某某开幕式还有 [<script language="JavaScript" type="text/javascript">djs()</script>] 天
第六种:Javascript倒计时器 - 采用系统时间自校验
这次利用系统时间自校验倒计时, 无需手工调校使得倒计时更为精确, 代码及详细注释如下:
<span id="clock">00:01:11:00</span> <input id="startB" type="button" value="start countdown!" onclick="run()"> <input id="endB" type="button" value="stop countdown!" onclick="stop()"> <br> <input id="diff" type="text"> <input id="next" type="text"> <script language="Javascript"> /* This notice must be untouched at all times. countdown.js v. 1.0 The latest version is available at http://blog.csdn.net/yjgx007 Copyright (c) 2004 Xinyi.Chen.

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:
天 小时 分 秒 2013年01月22日 15:44:23 星期二
