Similar TutorialsJavascript for clock: Code: function showTime (dateObj) {
thissecond=dateObj.getSeconds();
thisMinute=dateObj.getMinutes();
thisHour=dateObj.getHours();
// change thisHour from 24-hour time to 12-hour time by:
// 1) if thisHour < 12 then set ampm to "a.m." otherwise set it to "p.m."
var ampm = (thisHour < 12) ? "a.m." : "p.m.";
// 2) subtract 12 from the thisHour variable
thisHour = (thisHour > 12) ? thisHour - 12 : thisHour;
// 3) if thisHour equals 0, change it to 12
thisHour = (thisHour == 0) ? 12 : thisHour;
// add leading zeros to minutes and seconds less than 10
thisMinute = thisMinute < 10 ? "0"+thisMinute : thisMinute;
thisSecond = thisSecond < 10 ? "0"+thisSecond : thisSecond;
return thisHour + ":" + thisMinute + ":" + thisSecond + ampm;

heres where you can see it in action http://the-test.comoj.com/files/working-clock.html im just asking if there are any errors or if theres a better way to do this Thanks for clicking on the link and i presume while you are here on my thread yo u will try to help me So here is the situation. I am building webpage that displays a clock , a ticker box and a countdown(alarm clock). I have found many previously coded alarm clocks/countdown timers but they dont do what i need. Then what do you need you might be asking yourself?! - I need a countdown timer with background in MySQL database(there will be multiple events in that database) and then checks which is the next one( Alarms will be in HH:MM format so they can be activated every day), after the check it displays a countdown(logical eh?) until that event - when it reaches that event it should redirect to some other site(which will return user to the same site after 15 min pause) and then All over again, check which is next, countdown , redirect , AGAIN This website is designed not to be clicked or anything - it should work by itself. Are YOU able to help me? (Just a fair warning - Im a newb in javascript so dont be too harsh on me) hello all, this is my first time on this site and i can usally find all the information i need on google. However iv run into a problem while coding a countdown timer for students in my school i will be hosting it as a mobile website. what im having problems with is getting not the system time, but 1 syncronized time source ex. The official U.S.time or any other single time source if that one will not be the best. any suggestions? ps. i am completely new to js so make any suggestions and please explain throughly. Thanks! I'm trying to convert A world Population Counter from Flash into HTML/Javascript. But I'm having difficulties and It would be great if someone can help me out. The sample show a analog clock, But the html version I want should use just a digital clock, it's simpler I think http://www.webstylelabs.com/worldclock2.swf http://www.webstylelabs.com/actionscript.txt Here is my code, http://www.webstylelabs.com/clock.html So just plain input digital counter is ok I appreciate any help Hey everyone. I need a little help and I'm not an expert by any stretch of the imagination with javascript. I have a simple little code script and I'd like either the onClick function (or the entire code itself, whichever is easiest) to only load once every 24 hours for each IP address. So "123.1.22.333" should only get the effect of this code once every 24 hours regardless if they revisit my site 5 times a day let's say. So here's my little script: Code: <script language="JavaScript">
function goNewWin() {
TheNewWin=window.open("http://google.com",'Google','toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1');
TheNewWin.blur();
}
</script>
<body onClick="goNewWin()">
Any help would be very appreciated. Thanks! Hi, I have a webpage with a world clock. On the clock page are 12 buttons (World Cities). When the user clicks these buttons. The time for the relevant world city is displayed. (The time is updated by an on.click function for each individual button. That either subtracts or adds the hours from GMT. For example. If the time is GMT 18:00:00. The user clicks the Paris button and the function adds 1 hour to result in 19:00:00) However. If the GMT time is for example 21:00:00 and the user clicks the Tokyo button (GMT+9 hours). The time displayed is 30:00:00. So I have been trying to work out how I can stop the time adding past 23:59:59. This is probably so simple which is probably why I cant find any help online. It has stumped me and any help would be appreciated. I have copied and pasted my code below in the hope that helps. Thanks in advance if you can offer any advice. Code: <script>
function start() {
GMToffset = 0;
t=setInterval('digitalclock()',500);

Hi All, how do I trim leading zero in a date e.g 08/08/2003 to become 8/8/2003. thanks I have the following which returns the date in the format I need it in but it does not have the leading zero's Code: var wholeDate = getTheDay();
function getTheDay(){
var d = new Date();
var year = d.getFullYear();
var numMonth = d.getMonth() + 1;
var day = d.getDate();
var whole = year + '-' + numMonth + '-' + day;
alert(whole);
return whole;
}
Would return todays date as 2012-1-5 How do I get the date returned like 2012-01-05 ? Hello all is it possible to strip leading (meaning at the VERY begining of the text) and trailing (anything at the end of the text) carriage returns with reg ex? so if smbody enters return return return start txt entry ----> keep all other returns in paragraph sloppy ending retrun return return it would remove the start and end returns I'd like to add it to this if possible.

Any help will be appreciated. Hello, I am trying to create a clock for my video game. I need to begin the clock at zero and count while the game is going. I need to have the clock count in standard minutes and seconds but not be based on the actual time of day. I am coding in javascript for an applet.
I figured if there was one it would be a Javascript but does anyone know of a countdown clock that almost looks like a counter/turnstile number row? Like this sorta: I've been looking for one where I have the numbers look just like that and 'push' upward as the times (days, minutes, seconds) go on. Hopefully someone knows of a script >< Thanks alot!!! Hello, I'm somewhat new to JavaScript and for my website, I decided to make a clock for the website in this format: Saturday, October 17, 2009 5:56:14 p.m. The only issue is that it won't update every second. Below is the coding: External JavaScript: Code: function dateClock()
{
// Coding
}
setTimeout("dateClock()", 1000);
HTML: Code: ...
<script src="date.js" type="text/javascript">
</script>
</head>
<body>
<script type="text/javascript">
document.write("<p style='margin:-15px 0px;background-color:black;position:fixed;padding:5px;'>"+Day+", "+Month+" "+date+", "+Year+"<br />"+Hour+":"+Minute+":"+Sec+" "+Suffix+"</p>");
</script>

For the past few days I've been having trouble trying to figure out how to do something. I want to code a world population clock similar to the one here, but simpler: I want the user to be able to choose future years up to 2020 (just years, not months/days), and have the population grow by 1 percent each year. So far I have a code for the world population, but I have no clue where to begin in terms of making a list of the years with the option to increase the population. Could anyone point me in the right direction? I'd appreciate any help! Heres the code I have: <body> <script type="text/javascript"> function maind(){ startdate = new Date() now(startdate.getYear(),startdate.getMonth(),startdate.getDate(),startdate.getHours(),startdate.getM inutes(),startdate.getSeconds()) } function ChangeValue(number,pv){ numberstring ="" var j=0 var i=0 while (number > 1) { numberstring = (Math.round(number-0.5) % 10) + numberstring number= number / 10 j++ if (number > 1 && j==3) { numberstring = "," + numberstring j=0} i++ } numberstring=numberstring if (pv==1) {document.getElementById("worldpop").innerHTML=numberstring } } function now(year,month,date,hours,minutes,seconds){ startdatum = new Date(year,month,date,hours,minutes,seconds) var now = 5600000000.0 var now2 = 5690000000.0 var groeipercentage = (now2 - now) / now *100 var groeiperseconde = (now * (groeipercentage/100))/365.0/24.0/60.0/60.0 nu = new Date () schuldstartdatum = new Date (96,1,1) secondenoppagina = (nu.getTime() - startdatum.getTime())/1000 totaleschuld= (nu.getTime() - schuldstartdatum.getTime())/1000*groeiperseconde + now ChangeValue(totaleschuld,1); timerID = setTimeout("now(startdatum.getYear(),startdatum.getMonth(),startdatum.getDate(),startdatum.getHours( ),startdatum.getMinutes(),startdatum.getSeconds())",200) } window.onload=maind </script> Current world population (estimated): <span id="worldpop" style="font-weight: bold"></span>. </body> hey im simply tryna make a 24 hours countdown, reg ardless of timezones, computer clock etc., just a straight 24 h our stretch. here is what i have, somehow its not working, any help on fixing>?
