Countdown clock

**monkeyvu** · 02-25-2008, 11:22 PM

Hi all,

I'm having an issue with the countdown clock. I use the code at http://www.hashemian.com/tools/javascript-countdown.htm

In that site, it seems that every thing is ok. However, in my site it's not working properly...

Here is my ColdFusion page (you can replace with another language, I just use the now() function of CFusion, just because I need to get the Time on server, not on Client)

Code:

<cfoutput>
<html>

<script language="JavaScript">
TargetDate = "#DateFormat('2-29-2008', 'mm/dd/yyyy')#" + " " + "#TimeFormat('16:00', 'h:MM:ss tt')#";
Now = "#DateFormat(now(), 'mm/dd/yyyy')#" + " " + "#TimeFormat(now(), 'h:MM:ss tt')#";
CountActive = true;
CountStepper = -1;
LeadingZero = true;
DisplayFormat = "%%D%% D, %%H%% H, %%M%% M, %%S%% S.";
FinishMessage = "This item has expired";

</script>


<body>
	<script language="javascript" type="text/javascript" src="scripts/countdown.js"></script>
</body>
</html>
</cfoutput>

And the JavaScript code is as following

Usage Sample:

<script language="JavaScript">
TargetDate = "12/31/2020 5:00 AM";
BackColor = "palegreen";
ForeColor = "navy";
CountActive = true;
CountStepper = -1;
LeadingZero = true;
DisplayFormat = "%%D%% Days, %%H%% Hours, %%M%% Minutes.";
FinishMessage = "It is finally here!";
</script>
<script language="JavaScript" src="http://scripts.hashemian.com/js/countdown.js"></script>
*/

function calcage(secs, num1, num2) {
  s = ((Math.floor(secs/num1))%num2).toString();
  if (LeadingZero && s.length < 2)
    s = "0" + s;
  return "<b>" + s + "</b>";
}

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='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.";
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(Now);
if(CountStepper>0)
  ddiff = new Date(dnow-dthen);
else
  ddiff = new Date(dthen-dnow);
gsecs = Math.floor(ddiff.valueOf()/1000);
CountBack(gsecs);

If we wait for about 2 minutes then press F5. The time will be different...For example, when I open the page, the time is ... 10 minutes 30sec, after 2 minutes, the time now is 8 minutes 30 sec...at this time I press F5...The page is loaded again and the time will be 8 minutes 49sec... or sometimes it will be 7 minutes 30 sec...

I just guess the clock is running faster than the real time...but ...sometimes it's faster and sometimes it's slower....so I can't understand...

Do you have any ideas? Thanks very much

Hi!
If you need the answer (after 4 years!) here it is:

first of all It's not your fault. It's because of inner scripting.
One second calculates at 995 m.s. So Yeah, u guessed right

, It's faster!

I wrote anathor script (based on this script) and you can find it here:

You can press F5 (even after 10 hours!) and the time won't be changed.

Hope I helped you.

Sorry for my bad language! (Because, u know, English is not my native language)
