下面小编就为大家带来一篇JS倒计时实例_天时分秒。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧
HTML代码：
<div> 距离结束时间： <div> <b> </b>天 <b> </b>时 <b> </b>分 <b> </b>秒 </div> </div>
JavaScript代码：
<script type="text/javascript"> setTimeout("show_time()",1000); var time_wrap = document.getElementByIdx_x("times_wrap"); var time_d = document.getElementByIdx_x("times_d"); var time_h = document.getElementByIdx_x("times_h"); var time_m = document.getElementByIdx_x("times_m"); var time_s = document.getElementByIdx_x("times_s"); var time_end = new Date("2012/10/29 08:00:00"); // 设定结束时间 time_end = time_end.getTime(); function show_time(){ var time_now = new Date(); // 获取当前时间 time_now = time_now.getTime(); var time_distance = time_end - time_now; // 结束时间减去当前时间 var int_day, int_hour, int_minute, int_second; if(time_distance >= 0){ // 天时分秒换算 int_day = Math.floor(time_distance/86400000) time_distance -= int_day * 86400000; int_hour = Math.floor(time_distance/3600000) time_distance -= int_hour * 3600000; int_minute = Math.floor(time_distance/60000) time_distance -= int_minute * 60000; int_second = Math.floor(time_distance/1000) // 时分秒为单数时、前面加零站位 if(int_hour < 10) int_hour = "0" + int_hour; if(int_minute < 10) int_minute = "0" + int_minute; if(int_second < 10) int_second = "0" + int_second; // 显示时间 time_d.innerHTML = int_day; time_h.innerHTML = int_hour; time_m.innerHTML = int_minute; time_s.innerHTML = int_second; setTimeout("show_time()",1000); }else{ time_d.innerHTML = time_d.innerHTML; time_h.innerHTML = time_h.innerHTML; time_m.innerHTML = time_m.innerHTML; time_s.innerHTML = time_s.innerHTML; // clearTimeout(timerID) } }; </script>
