Javascript倒计时

我已经搜索过网络,但所有现成的网站都是您特定日期的地方,并且计算到那个日期.我需要的是从"27分43秒"(以这种格式)从它们落在页面上一直到0的状态简单倒计时,任何人都可以获得任何片段？

这样的事情应该可以解决问题.我很无聊,决定自己做而不是谷歌搜索.只需将分钟和秒设置在顶部,然后将onload中的倒计时调用更改为要更新的元素的id.

我做了一个简单的倒计时你可以使用.

它正在生成以下格式:

DAYS X,HOURS X,MINUTES X,SECONDS X.

JS:

countIt();

function countIt(){
    year = 2013;
    month = 05;
    day = 28;
    hours = 12;
    minutes = 00;
    seconds = 00;

    setTimeout(function(){
    endDate = new Date(year, (month - 1), day, hours, minutes, seconds, 00);
    thisDate  = new Date();
    thisDate  = new Date(thisDate.getFullYear(), thisDate.getMonth(), thisDate.getDate(), thisDate.getHours(), thisDate.getMinutes(), thisDate.getSeconds(), 00, 00);

    var daysLeft = parseInt((endDate-thisDate)/86400000);
    var hoursLeft = parseInt((endDate-thisDate)/3600000); 
    var minutsLeft = parseInt((endDate-thisDate)/60000);
    var secondsLeft = parseInt((endDate-thisDate)/1000);

    seconds = minutsLeft*60;
    seconds = secondsLeft-seconds;

    minutes = hoursLeft*60;
    minutes = minutsLeft-minutes;

    hours = daysLeft*24;
    hours = (hoursLeft-hours) < 0 ? 0 : hoursLeft-hours;

    days = daysLeft;

    startCount(days, hours, minutes,seconds);
    }, 1000);
}

function startCount(days, hours, minutes, seconds){
    document.getElementById("counter").innerHTML="DAYS "+days+", HOURS "+hours+", MINUTES "+minutes+", SECONDS: "+seconds;
    countIt();
}
