基于JS实现的倒计时程序实例

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。
