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。
