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。
