本文介绍了一个使用JavaScript编写的倒计时脚本，该脚本可以计算并显示指定日期（如2012年元旦）之前的剩余天数、小时数、分钟数和秒数。通过设置定时器每250毫秒更新一次时间，确保了时间的实时性。


<script language=JavaScript>
var now = new Date();
function GetServerTime()
{
var urodz = new Date("12/31/2011 23:59:59");
now.setTime(now.getTime()+250);
days = (urodz - now) / 1000 / 60 / 60 / 24;
daysRound = Math.floor(days);
hours = (urodz - now) / 1000 / 60 / 60 - (24 * daysRound);
hoursRound = Math.floor(hours);
minutes = (urodz - now) / 1000 /60 - (24 * 60 * daysRound) - (60 * hoursRound);
minutesRound = Math.floor(minutes);
seconds = (urodz - now) / 1000 - (24 * 60 * 60 * daysRound) - (60 * 60 * hoursRound) - (60 * minutesRound);
secondsRound = Math.round(seconds);
document.getElementById("date").innerHTML = daysRound;
document.getElementById("time").innerHTML = hoursRound + ":" + minutesRound + ":" + secondsRound;
}
setInterval("GetServerTime()",250);
</script><p><span>距离2012年元旦还有</span><span id="date"></span><span class="white14b">天</span><span id="time"></span>
