时分秒倒计时的js实现，如图：

闲话少说，直接上代码。

html代码：

<div id="timer" data-timer="0628140203" style="font-size:20px">剩余天数：<span id="timer_d">0</span>天<span id="timer_h">0</span>时<span id="timer_m">0</span>分<span id="timer_s">0</span>秒</div>

js代码：

timer('timer');//调用方法//时分秒倒计时方法function timer(eleId){var element=document.getElementById(eleId);if(element){endTimer=element.getAttribute('data-timer');var endTime=new Date(parseInt(endTimer.substr(0,4), 10),parseInt(endTimer.substr(4,2), 10),parseInt(endTimer.substr(6,2), 10),parseInt(endTimer.substr(8,2), 10),parseInt(endTimer.substr(10,2), 10),parseInt(endTimer.substr(12,2), 10));var endTimeMonth=endTime.getMonth()-1;endTime.setMonth(endTimeMonth);var ts = endTime - new Date();if(ts>0){var dd = parseInt(ts / 1000 / 60 / 60 / 24, 10);var hh = parseInt(ts / 1000 / 60 / 60 % 24, 10);var mm = parseInt(ts / 1000 / 60 % 60, 10);var ss = parseInt(ts / 1000 % 60, 10);dd = dd<10?("0" + dd):dd; //天hh = hh<10?("0" + hh):hh; //时mm = mm<10?("0" + mm):mm; //分ss = ss<10?("0" + ss):ss; //秒document.getElementById("timer_d").innerHTML=dd;document.getElementById("timer_h").innerHTML=hh;document.getElementById("timer_m").innerHTML=mm;document.getElementById("timer_s").innerHTML=ss;setTimeout(function(){timer(eleId);},1000);}else{document.getElementById("timer_d").innerHTML=0;document.getElementById("timer_h").innerHTML=0;document.getElementById("timer_m").innerHTML=0;document.getElementById("timer_s").innerHTML=0;}}}
