JavaScript - Timer
How could I lock an "Enter" link on an intro page with a 30 second timer that is displayed on the bottom of the page and disables the "Enter" link so that visitors have to wait 30 seconds to read the rules/announcements before entering?

Hi I am working on a chat application and am a bit stuck...In the database I have a field status which is set 1 for online and 0 for offline (PHP/MySQL)(at time of logging in/out), this shows the users status on a webpage. What I need is to know if there is a way I can set a timer so that if the user has been inactive for X amount of time, the database is auto updated and user is offline (1 set to 0). Thanks for any help I recieve I'm trying to build a time but it isn't displaying on screen Code: <html>

Hi everyone, I need a countdown timer that will count down exactly from a time that i set. i want it to count in this format: hh:mm:ss. i need it for a online shop , at the main page there are few products for sell and i want each one of them to have its own countdown timer. in addition when it will get to 00:00:00 i want that it will automatically add like 5 hours and continue counting down.. P.s i dont know javascript.. thanks guys I am making a website and the page is oriented around a countdown system. If the timer ever reaches 0, the whole thing will stop. Below are the specifics: I need a countdown timer that runs from 30 seconds to 0 seconds. If the timer is at 0 seconds, the script runs php code #1 (which makes the timer stop and if any user refreshes the page, it will still stay at zero). There is also two buttons. If user clicks on button #1, the timer will get reset to 30 seconds remaining. Then the script will run the php code #2 (which allows the timer to begin counting down again from 30 seconds). If user clicks on button #2, the timer will get reset to 5 seconds remaining and same thing follows as the first button. And obviously the timer should show the same number (seconds remaining) for all the users on the website! Thank You Hi All, I am trying to set up a countdown function that will be called on the click of a button. Function is below Code:
function countDown(sec, min) {
sec--;
if (sec == -01) {
sec = 59;
min = min - 1;
} else {
min = min;
}
if (sec<=9) { sec = "0" + sec; }
time = (min<=9 ? "0" + min : min) + " min and " + sec + " sec ";
if (document.getElementById) { theTime.innerHTML = time; }
SD=window.setTimeout("countDown();", 1000);
if (min == '00' && sec == '00') { sec = "00"; window.clearTimeout(SD); }
}
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
});
However I get an error after one second. Script can be found here - http://www.jivalot.co.uk/m.php Can anyone help? Kind regards, Slate Hi im new to javascript , i have a game when 2 or more players enter the game a button appears one of the players clicks the button the game starts, what i want to do is when 2 or more players join the game i want the game to start, and not start by using the button. here is the code for the button.

The timer is like the one of Swoopo where it counts down to zero. When a user places a bid it should add on time such as 10 seconds. First of all what would be the best way of running a timer? A cron-job? Next problem is adding the time and getting it to update in everyones browser I have checked other posts on here but the posters seem to know the basics of my problems but Im not sure I do. any help would be appreciated Hello everyone. I'm using the script Old Pedant posted here (huge thanks man!), however, I'm looking to have the timer display six numbers at all times. For example: If the timer has 15 hours, 35 minutes, and 10 seconds left it is currently displaying as: 15:35:10 - Perfect! If the timer has 5 hours, 35 minutes, and 10 seconds left it is currently displaying as: 5:35:10 - Humm, not so perfect. In the second example, would like the timer to keep a zero in front of the hours when ever it drops below 10. So the second example should display as: 05:35:10. Any help is greatly appreciated. Posted below is the modified code I'm using. Thanks! Code: <html>

<script type="text/javascript">
// really really simple to get the time from the server
// this is for an ASP server:
//var serverTime = <%= DateDiff("s",#1/1/1970#,Now())%>;
// PHP Servers:
var serverTime = <?php echo time(); ?>;
// serverTime will hold the number of seconds since 1/1/1970 0:00:00 as it is on the server
// we must adjust it to compensate for GMT offset
// My server is on Pacific Daylight Time, so 7 hours offset:
serverTime += 0 * 3600; // 7 hours, 3600 seconds per hour
// NOTE: This adjustment MAY NOT be needed for PHP servers...I dunno.
//
// so calculate how far off the client is from the server:
var now = new Date();
var clientTime = now.getTime(); // number of *milliseconds* since 1/1/1970 0:00:00 on client
serverTime *= 1000; // convert server time to milliseconds, as well
// the client and server disagree by this much:
var clockOff = serverTime - clientTime; // could well be negative!
// hopefully you can see, from basic algebra, that
// serverTime = clientTime + clockOff
// we want target to be 0:00:00 of next day
var target = new Date( serverTime ); // serverTime in JS form
// so bump the day by one and leave time as 0,0,0:
target = new Date( target.getFullYear(), target.getMonth(), target.getDate() + 1 );
// and now ready for our timer countdown:
var ticker = null; // the interval timer
function countdown( )
{
var clientNow = ( new Date() ).getTime();
var serverNow = clientNow + clockOff; // see? this is where we use that offset!

Hello, I'm on a RPG game and they have a automatic logout timer to stop people from using bots to play, the only problem with it is, if someone lets the timer run out, it won't let the user log back in for a time (This time could be anywhere from 5 minutes to 3 hours from what other members have told me) Now java isn't my strong point (But I'm learning ^_^) and I'm not 100% sure if this error is related to java or some other code format. Using the develop tool in Safari I was able to find the code, and its telling me thats its java, I'm sorry if this is in the wrong place if its not Java after all. I'm wondering if looking over this code, someone might be able to find the problem or might have any tips to make it work better. (Note; I'm not the admin or owner of the RPG, but the owner hasnt done anything about it mainly cause they are to lazy I think?? or might not know how to fix it.

Thank you to anyone who helps. - zerobeat, Jack. Hello, i need one script, which will remove the timer and i’ll be able to start download the file without waiting the time… Okay, i dont need such things… I need only one simple thing… Without any premium accounts… It should remove the timer (30 sec)… That’s everything i want… Link: *HIDEN* Thanks. Contact me via pm or skype - bahurz1 hi, i am currently trying to write a javascript program; it would be for a library reservation system. this would be put on the computers with sessions from 15 minutes to 2 hours (in 15 minute chunks i.e, 15, 30, 45, 1 hour). this program would countdown the remaining time on their session, with pop-up messages appearing every so often. at the end of the session, the program will have to automatically log the user off. i am a student studying javascript, and haven't got any idea how to even start can anyone give me a helping hand to get me started. thanks I am trying to make an image show then stop showing. I am trying to use: document.image.src This is the code. <HTML> <HEAD> <!-- BlackHole Pointer Display/Hide --> <script language="javascript"> <!-- function blkhlpntr() { document.images.src="http://www.proamrodeo.com/gif/menu/blackholepointer.gif; setTimeout('blkhlpntr()',5000) } //--> </script> </HEAD> <BODY onload="setTimeout('blkhlpntr()',5000)" BGCOLOR="#FFFFFF"> <!-- Black Hole Pointer --> <DIV id="blkhlpntr" STYLE="position:absolute; top:70px; left:840px; width:90px; border-width:0; visibility:visible; z-index:1"> <img src="http://www.proamrodeo.com/gif/menu/blackholepointer.gif" width="15" height="48"> </DIV> </BODY> </HTML> This should load two(2) of the images to test it anyway.

I would like to have a countdown timer on my website that will count down from 12:00:01 am server time and end at midnight again of the same day (the clock should count down a full 24 hours) then it will automatically reset itself and count down again each and every day starting from 1 second after midnight. The count down should display hours : minutes : seconds just like a digital watch. I would also like to it to go with the server time and not client computer time so it will only count down according to the server time. One more thing .... each day a new trivia question will be posted and ppl have 1 day to answer the trivia question for a chance to win something (that is why the script is counting down). Will the script be able to automatically load a new trivia each day at midnight as the timer resets or do i have to load the trivia manually? If im getting way out of my head here then lets forget this last part. If it can be done i will certainly appreciate the advice. Hi guys, I'm building a page which has a countdown timer on it (days, hours, mins) and I honestly really don't know much about Javascript at all. I have spent over half a day looking through tutorials and code snippets and think I'm close, but I'm still having trouble with the output. I need to pull out the days/hours/mins separately as they sit within different HTML elements. The days appear to be displaying correctly, but the hours is showing 3 digits instead of 2 and the mins is showing 5 digits instead of 2: 32 days, 764 hours, 45845 mins Here is the code I'm using: Code: var now = new Date();
var theevent = new Date("June 18 2011 10:00:00");
var seconds = (theevent - now) / 1000;
var mins = seconds / 60;
var hours = mins / 60;
var days = hours / 24;
ID=window.setTimeout("update();", 1000);
function update() {
now = new Date();
seconds = (theevent - now) / 1000;
seconds = Math.round(seconds);
mins = seconds / 60;
mins = Math.round(mins);
hours = mins / 60;
hours = Math.round(hours);
days = hours / 24;
days = Math.round(days);
document.getElementById('days').innerHTML = days;
document.getElementById('hours').innerHTML = hours;
document.getElementById('mins').innerHTML = mins;
ID=window.setTimeout("update();",1000);
}
Thanks a bunch in advance... Hi everyone I need a function which will record the amount of time that a window has been open for. Upon load, the function should start a timer, and upon close, the function should store the number of minutes and seconds to a field on the form called 'Time'. My concern with this is whether you can write to a DOM element upon closre of a window, or whether we loose that ability as soon as the close event happens? if you could help priovide ideas around doing this then I'd be very grateful Dom I found this countdown timer online that starts when the page loads at 30 seconds and counts down to zero. What I need for it to do however is once it hits 0 it needs to automatically reset itself back to 30 seconds. It's being used in conjunction with a online (not a chat room) chatterbot where people often abuse the bot with foul language. The idea being to stop them from entering text to the bot for 30 seconds. I'm using these lines in the chatterbot where xxx would be the foul language. The stopTalk part prevents entering text for 30 seconds. The display() triggers the countdown. However, once it hits 0 it's dead in the water. If someone types another bad word the timer isn't going to work. Note: The timer is just a visual diplay so the user can see how long he must wait. The StopTalk below is working fine to stop the user from entering text. That part isn't the problem. Code: if (input.search("xxx")!= -1)
{document.result.result.value = "Stop the foul language. You can no longer enter text for 30 seconds";
display()
stopTalk = setTimeout('icon.src=icon1.src;stopTalk=false;',30000)
return true;}
1) Because this is an online chatterbot that temporarily stores information about the user I can't restart the timer by refreshing the page or I would lose that information. 2) I don't want to use a button to reset the timer. If at all possible I want the timer to reset automatically. Any help would be appreciated. Code: <form name="counter"><input type="text" size="8"
name="d2"></form>
<script>
<!--
//
var milisec=0
var seconds=30
document.counter.d2.value='30'
function display(){
if (milisec<=0){
milisec=9
seconds-=1
}
if (seconds<=-1){
milisec=0
seconds+=1
}
else
milisec-=1
document.counter.d2.value=seconds+"."+milisec
setTimeout("display()",100)
}
