javascript倒计时...

JS脚本是在网上找到的，然后进行了改进，弥补了不足之处。

JS脚本

<mce:script language="javascript" type="text/javascript"><!-- var interval = 1000; function ShowCountDown(year, month, day, divname) { var now = new Date(); var endDate = new Date(year, month - 1, day, 14, 07); var leftTime = endDate.getTime() - now.getTime(); var leftsecond = parseInt(leftTime / 1000); var day1 = Math.floor(leftsecond / (60 * 60 * 24)); var hour1 = Math.floor((leftsecond - day1 * 24 * 60 * 60) / 3600); var hour = Math.floor((leftsecond - 60 * 60) / 3600); //如果小时为负数 显示0 if (hour > 0) { } else { hour = 0; } if (day1 < 0) { hour = hour1 } var minute = Math.floor((leftsecond - day1 * 24 * 60 * 60 - hour1 * 3600) / 60); var second = Math.floor(leftsecond - day1 * 24 * 60 * 60 - hour1 * 3600 - minute * 60); var cc = document.getElementById(divname); //如果结束时间为负数 就显示0 if (leftTime > 0) { cc.innerHTML = hour + "小时" + minute + "分" + second + "秒"; //如果显示年份 取消注释 //cc.innerHTML = "距离" + year + "年" + month + "月" + day + "日还有：" + hour + "小时" + minute + "分" + second + "秒"; } else { cc.innerHTML = 0 + "小时" + 0 + "分" + 0 + "秒"; } } //showData是DIV的ID 2010，8，10表示是年月日的意思 参数根据自己的需求设置。 window.setInterval(function () { ShowCountDown(2010, 8, 10, 'showData'); }, interval); // --></mce:script> 

HTML:

<div id="showData"> </div>
