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。
