js倒數小程式實作程式碼,可以精確到天和精確到秒
#我們這裡只要自己定義一下s與urodz的值就可以隨意定義任何日期或節日的倒數功能了,各位朋友可加以修改。
精確到天的倒數計時
程式碼如下:
<script language="JavaScript"> <!-- // (c) Henryk Gajewski var urodz= new Date("09/19/2013"); var s="中秋节"; var now = new Date(); var ile = urodz.getTime() - now.getTime(); var dni = Math.floor(ile / (1000 * 60 * 60 * 24)); if (dni > 1) document.write(""+s+"还有"+dni +"天") else if (dni == 1) document.write("只有2天啦!") else if (dni == 0) document.write("只有1天啦!") else document.write("好象已经过了哦!"); // -->
精確到秒的javascript倒數程式碼
HTML程式碼:
程式碼如下:
<form name="form1"> <p align="center" align="center"> <center>离2010年还有:<br> <input type="textarea" name="left" size="35" style="text-align: center"> </center> </p> </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>
