About LinkBacksHi guys, I need a VERY simple count down. I need something to count down 20 minutes, then loop. I need this as a way to show users how much longer they have until database clears.

Add this to your <head>:
add onload="startTimer()" to your <body> tagHTML Code:<script type="text/javascript"> //How much time there is on the timer when the page has loaded? (in seconds) var timeleft = 20*60 //How much time does the timer have to reset to? (in seconds) var resettime = 20*60; function countdown() { setTimeout(countdown, 1000); if(timeleft > 0) { timeleft--; } else { timeleft = resettime; } document.getElementById("time").innerText = ((timeleft-timeleft%60)/60)+":"; if(timeleft%60 < 10) document.getElementById("time").innerText += "0"; document.getElementById("time").innerText += ""+timeleft%60; document.getElementById("time").textContent = document.getElementById("time").innerText; } function startTimer() { timeleft++; countdown(); } </script>
egand then use a <span> with id "time" where you want to put your timer.HTML Code:<body onload="startTimer()">
egTested in IE and FF (omfg, WILL YOU FINALLY WORK?!)HTML Code:<span id="time"></span>

Real programmers don't document their code - if it was hard to write, it should be hard to understand.

That code looks alright for the most part. The only thing is that the OP said that after 20 minutes, the db is cleared. This sounds to me like a cron job rather than something that would rely on the clients. In this case it would be a good idea to have php store the timestamp of the last clearing in the db(in a table that isn't cleared, of course), then have that timestamp loaded into the JS so it can count down from the approximate time remaining. That's basically just changing
var timeleft = 20*60;
to
var timeleft = <?php print (($t = $lastclear + 1200 - time()) > 1200 ? 1200 : $t);?>;
where $lastclear is the time of the last clearing retrieved from the db.

Yes, I realised this, but he said very simple, so I supposed he just wanted an estimation.
