这篇文章主要介绍了基于JS实现的倒计时程序,实例分析了javascript实现倒计时计数的相关技巧,非常简单实用,需要的朋友可以参考下
本文实例讲述了基于JS实现的倒计时程序。分享给大家供大家参考。具体实现方法如下:
- 剩余时间:<i id="expireTime"></i>
- <script type="text/javascript">
- var expire = 2412169;
- var expireTime = function(expires){
- if(expires > 0){
- var second = expires;
- }else{
- var second = "0 分";
- return second;
- }
- var day = hour = min = "";
- if(second>86400){
- day = Math.floor(second/86400)+"天 ";
- second = second%86400;
- }
- if(second>3600){
- hour = Math.floor(second/3600)+"时 ";
- second = second%3600;
- }
- if(second>60){
- min = Math.floor(second/60)+"分 ";
- second = second%60;
- }
- second = second+"秒";
- return day+hour+min+second;
- }
- var timeEle = document.getElementById("expireTime");
- var timer = window.setInterval(function(){
- timeEle.innerHTML = expireTime(expire--);
- if(expire<0){
- clearInterval(timer);
- }
- },1000);
- </script>
希望本文所述对大家的javascript程序设计有所帮助。
