The second kind: XXX Games

Third type: Hour countdown



HTML code:
<scriptlanguage= "JavaScript" >
<!--
var maxtime = 60*60//One hours, calculate by seconds, adjust yourself!
function Countdown () {
if (maxtime>=0) {
Minutes =math.floor (MAXTIME/60);

msg = "+minutes+" and "+seconds+" seconds "at the end of the distance";
document.all["Timer"].INNERHTML=MSG;
if (MaxTime = = 5*60) alert (' Note, there are 5 minutes! ');
--maxtime;
}
else{
Clearinterval (timer);
Alert ("Time to, end!");
}
}
Timer =setinterval ("Countdown ()", 1000);
-
</SCRIPT>
<div id= "Timer" style= "color:red" ></div>






Fourth type: The simplest countdown



HTML code:
<scriptlanguage= "JavaScript" >
<!--Begin
var timedate= new Date ("january14,2006");
vartimes= "Postgraduate examination";
var now = Newdate ();
var date = Timedate.gettime ()-now.gettime ();
var time = Math.floor (Date/(1000 * 60 * 60 *24));
if (time >= 0);
document.write ("<li><fontcolor= #DEDBDE > Now from 2006" +times+ "also: <fontcolor= #ffffff ><b>" + time+ "</b></font> days </font></li>");
End-To
</Script>






The fifth kind: The simplest countdown two



HTML code:
<script language= "JavaScript" type= "Text/javascript" >
function DJs () {
var urodz= newdate ("11/12/2008");
var now = new Date ();
var num
var ile = Urodz.gettime ()-now.gettime ();
var dni = Math.floor (ile/(1000 * 60 * 60 *24));
if (dni>1)
Num=dni+1
else if (dni = = 1) num=2
else if (dni = = 0) num=1
else num=0
document.write (num)
}
</script>

From the opening ceremony there are [<script language= "JavaScript" type= "Text/javascript" >djs () </script>] Days
Fifth: JavaScript countdown timer-using system time self-calibration
The use of system time self-calibration countdown, no manual adjustment to make the countdown more accurate, code and detailed comments are as follows:

<spanid= "Clock" >00:01:11:00</span>
<input id= "STARTB" type= "button" value= "startcountdown!" Onclick= "Run ()" >
<input id= "endb" type= "button" value= "stopcountdown!" Onclick= "Stop ()" >
<br>
<input id= "diff" type= "text" >
<input id= "Next" type= "text" >
<scriptlanguage= "Javascript" >
var normalelapse = 100;
var nextelapse =normalelapse;
Varcounter;
var startTime;
var start =clock.innertext;
var finish = "00:00:00:00";
var timer = null;

Start running
function Run () {
Startb.disabled = true;
endb.disabled = false;
Counter = 0;
Initialization start time
StartTime = Newdate (). ValueOf ();

Nextelapse is timing time, initially 100 milliseconds
Note the SetInterval function: the time elapsed nextelapse (milliseconds) before OnTimer began to execute
Timer = Window.setinterval ("OnTimer ()", nextelapse);
}

Stop running
function Stop () {
startb.disabled = false;
Endb.disabled = true;
Window.cleartimeout (timer);
}

Window.onload = function () {
Endb.disabled = true;
}

Countdown function
function OnTimer ()
{

if (start = = finish)
{
Window.clearinterval (timer);
Alert ("Time is up!");
Return
}

var HMS = NewString (Start). Split (":");
var ms = Newnumber (hms[3]);
var s = newnumber (hms[2]);
var m = newnumber (hms[1]);
var h = newnumber (Hms[0]);

MS-= 10;
if (MS <0)
{
ms = 90;
S-= 1;
if (S < 0)
{
s = 59;
M-=1;
}

if (M < 0)
{
m = 59;
H-=1;
}
}

var ms = MS < 10? ("0" + ms): MS;
var ss = S < 10? ("0" + s): s;
var sm = m < 10? ("0" + m): M;
var sh = h < 10? ("0" + H): h;

Start = sh + ":" + SM + ":" + SS + ":" +MS;
Clock.innertext = start;

Clear the last Timer
Window.clearinterval (timer);

The time of the self-calibration system is time-out, and this results in the timing of the next new timer Nextelapse
counter++;
var countersecs = counter *100;
var elapsesecs = new Date (). ValueOf ()-starttime;
var diffsecs = countersecs-elapsesecs;
Nextelapse = Normalelapse +diffsecs;
Diff.value = Countersecs + "-" + elapsesecs + "=" +diffsecs;
Next.value = "Nextelapse =" +nextelapse;
if (Nextelapse < 0) Nextelapse = 0;

Start a new timer
Timer = Window.setinterval ("OnTimer ()", nextelapse);
}
</script>
