此倒计时调用时,需要指定终点的日期,日期格式为MM/dd/yyyy,倒计时秒针不停的跳动.例如终点时间为:12/05/2015 23:59:5

JS倒计时类:

var now = new Date();var endDate;//MM-dd-yyyyfunction GetServerTime() {    var urodz = new Date(endDate + " 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);
