我基本上是在我的一个网站上使用 javascript 倒计时，它包含我需要的一切，但是我想扩展它，但我对 js 比较陌生。基本上，它会在倒计时完成后显示一条消息，这很棒，但是我想在倒计时旁边显示一条消息，当倒计时到达 0 时，它会随着倒计时而被删除。

示例：“New Year in, {Countdown}”，因此新年文本和倒计时应该在它达到 0 时被删除并替换为完成的文本。

这是我正在使用的脚本：

    <script language="JavaScript">
TargetDate = "January/01/2014 12:00 am";
BackColor = "";
ForeColor = "#000";
CountActive = true;
CountStepper = -1;
LeadingZero = true;
DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
FinishMessage = "<span class='finish'>Finished!</span>";
</script>
<script language="javascript">
function calcage(secs, num1, num2) {
  s = ((Math.floor(secs/num1))%num2).toString();
  if (LeadingZero && s.length < 2)
    s = "0" + s;
  return "<span class='digit'>" + s + "</span>";
}

function CountBack(secs) {
  if (secs < 0) {
    document.getElementById("cntdwn").innerHTML = FinishMessage;
    return;
  }
  DisplayStr = DisplayFormat.replace(/%%D%%/g, calcage(secs,86400,100000));
  DisplayStr = DisplayStr.replace(/%%H%%/g, calcage(secs,3600,24));
  DisplayStr = DisplayStr.replace(/%%M%%/g, calcage(secs,60,60));
  DisplayStr = DisplayStr.replace(/%%S%%/g, calcage(secs,1,60));

  document.getElementById("cntdwn").innerHTML = DisplayStr;
  if (CountActive)
    setTimeout("CountBack(" + (secs+CountStepper) + ")", SetTimeOutPeriod);
}

function putspan(backcolor, forecolor) {
 document.write("<span id='cntdwn' style=' font-weight:bold; background-color:" + backcolor + 
                "; color:" + forecolor + "'> </span>");
}

if (typeof(BackColor)=="undefined")
  BackColor = "white";
if (typeof(ForeColor)=="undefined")
  ForeColor= "black";
if (typeof(TargetDate)=="undefined")
  TargetDate = "12/31/2020 5:00 AM";
if (typeof(DisplayFormat)=="undefined")
  DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds.";
if (typeof(CountActive)=="undefined")
  CountActive = true;
if (typeof(FinishMessage)=="undefined")
  FinishMessage = "";
if (typeof(CountStepper)!="number")
  CountStepper = -1;
if (typeof(LeadingZero)=="undefined")
  LeadingZero = true;


CountStepper = Math.ceil(CountStepper);
if (CountStepper == 0)
  CountActive = false;
var SetTimeOutPeriod = (Math.abs(CountStepper)-1)*1000 + 990;
putspan(BackColor, ForeColor);
var dthen = new Date(TargetDate);
var dnow = new Date();
if(CountStepper>0)
  ddiff = new Date(dnow-dthen);
else
  ddiff = new Date(dthen-dnow);
gsecs = Math.floor(ddiff.valueOf()/1000);
CountBack(gsecs);
</script>

任何帮助得到这个将不胜感激！

谢谢 ：）

我认为这是您的答案，如果我没有正确回答您的问题，请原谅。

DisplayFormat = "New Year in, {%%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds}.";

我看到你得到了简单的答案，但如果你想让它更干净一点，这里有一个 jQuery 插件：http: //jsfiddle.net/chrisdanek/C59hN/1/

只需定位一个带有日期的元素，就会变成一个计数器

$('p.counter').countdownCounter({
    format : 'New Year in %%D%% Days, %%H%% Hours, %%M%% Minutes, %%S%% Seconds!',
});

编辑：我为插件http://cou.io/code/countdown/创建了一个单独的页面，并添加了一些选项。
