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 "> <br> <input type ="textArea "name ="왼쪽 "size ="35 "style ="text-align : center "> </div> </form> <script language ="javaScript "> StartClock () var timerid = null; var timerrunning = false; 함수 showtime () {오늘 = 새 날짜 (); var whour = 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; 오늘 = 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,'+Houstleft+'小时,'+minuteleft+'分,'+secondleft+'秒'document.form1.left.value = temp; TIMERID = settimeout ( "showtime ()", 1000); 타임 런닝 = true; } var timerid = null; var timerrunning = false; 함수 stopClock () {if (TimerRunning) CLEARTIME AUTHER (TIMERID); 시간 시간 = 거짓; } function startClock () {stopClock (); showtime (); } //-> </script>第二种 ：某某运动会
html 代码 :
<! -javaScript 시작-> <script language = "javaScript"> <!-function digitalTime1 () {var deadline = new Date ( "08/13/2007") // 开幕倒计时 var sevential = "8 月 13日"var now () var diff = -480- now. 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) - (시간 * 60) var Second = Math.floor (1000 * 60) - (24 * 60 * 60) - (Minute*60) var Deadline_2 = 새 날짜 ( "08/13/2004") // 开幕后计时 var revinafy_2 = "8 月 13日"var now_2 = new date () var diff_2 = -480- now.gettimezoneoffset () // var var leaf_2 = (now__2.gettime () - deadline_2.gettime () + diff_2*60000 var day_2*.

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); 초 = Math.floor (Maxtime%60); msg = "距离结束还有"+mings+"分"+seconds+"秒"; document.all [ "타이머"]. innerhtml = msg; if (maxtime == 5*60) Alert ( '注意 注意, 还有 5 分钟!'); -마시 타임; } else {clearInterVal (타이머); 경고 ( "时间到 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"> <!- 시작 var timedate = new 날짜 ( "1 월 14,2006"); var times = "研究生考试"; var now = 새 날짜 (); var date = timedate.gettime () - now.gettime (); var time = math.floor (날짜 / (1000 * 60 * 60 * 24)); if (time> = 0); documb // 종료 -> </script>
第五种 ：最简倒计时二
html 代码 :
<script language = "javaScript"type = "text/javaScript"> function djs () {var urodz = 새 날짜 ( "11/12/2008"); var now = 새 날짜 (); 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
are ： 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, 代码及详细注释如下, 无需手工调校使得倒计时更为精确 :
