同一页面上的多个Javascript倒计时

嗨，我正在尝试向一个html页面添加几个javascript倒计时。我在下面包含了.js文件。现在我的页面只显示第一次倒计时

function cdtd () {
    var end = new Date("December 25, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('cdtd()',1000);

}

function countdown () {
    var end = new Date("May 31, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('countdown()',1000);

}

function cdtd3 () {
    var end = new Date("December 25, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('cdtd3()',1000);

}

function cdtd4 () {
    var end = new Date("December 25, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('cdtd4()',1000);

}

function cdtd5 () {
    var end = new Date("December 25, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('cdtd5()',1000);

}

function cdtd6 () {
    var end = new Date("December 25, 2013 00:01:00");
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
        clearTimeout (timer);
        document.write("Deal Ended");
    }
    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %=60;

    document.getElementById("daysBox").innerHTML = days;
    document.getElementById("hoursBox").innerHTML = hours;
    document.getElementById("minsBox").innerHTML = minutes;
    document.getElementById("secsBox").innerHTML = seconds;

    var timer = setTimeout('cdtd6()',1000);

}

函数cdtd（）{
var结束=新日期（“2013年12月25日00:01:00”）；
var start=新日期（）；
var timeDiff=end.getTime（）-start.getTime（）；
如果（timeDiff现在您每次调用函数时都引用一个框覆盖每个值

您希望使用查询选择器而不是getElementById

下面是一个使用jQuery的简单示例：

var cdtd = function(id,end) {
    var start = new Date();
    var timeDiff = end.getTime() - start.getTime();
    if (timeDiff <= 0) {
            clearTimeout (timer);
            document.write("Deal Ended");
    }

    var seconds = Math.floor(timeDiff / 1000);
    var minutes = Math.floor(seconds / 60);
    var hours = Math.floor(minutes / 60);
    var days = Math.floor(hours / 24);
    hours %= 24;
    minutes %= 60;
    seconds %= 60;
    $( id + " .days").html(days);
    $( id + " .hours").html(hours);
    $( id + " .minutes").html( minutes);
    $( id + " .seconds").html( seconds );
    console.log(id + " .hoursBox",$( id + " .hoursBox").length,id,end,hours,minutes,seconds)
    var timer = setTimeout(function(){cdtd(id,end)},1000);
}
cdtd("#counter1",new Date("December 25, 2014 00:01:00"));
cdtd("#counter2",new Date("October 31, 2014 00:01:00"));
cdtd("#counter3",new Date("January 1, 2014 00:01:00"));

var cdtd=函数（id，end）{
var start=新日期（）；
var timeDiff=end.getTime（）-start.getTime（）；
如果（timeDiff这里有几个问题需要解决：

每个倒计时计时器在存储时间字符串时使用相同的元素ID。这就是为什么只显示其中一个

如果任何一个倒计时达到零，则调用
document.write（）
将擦除整个页面

代码被重复了一遍又一遍。这应该是所有倒计时的一个常用函数。（如果需要再添加一个呢？再添加十个？）

虽然多个计时器可以工作，但您不需要它们。运行一个计时器并从中更新所有显示的时间

调用
setInterval（）
时，最好将函数引用作为第一个参数而不是字符串传递

考虑一下这些想法，看看你能想出什么，然后用你的新代码向我们汇报。：-）@Shanimal我在我的网站上使用了这个代码，问题是当计时器达到0000时，它会转到另一个页面并显示交易结束。我想要的是，当计时器达到0000时，它必须在同一页面的特定分区上显示消息。它不应该转到另一个页面。我已尝试删除它
如果（timeDiff），您可能希望熟悉面向对象编程的概念：有一点是肯定的，…您的所有函数都使用相同的ID更新元素。
