How to make a countdown which will restart again after 5 minutes?

I want to make a countdown which will restart after 5 minutes automatically, how to do it…

<html>
<head>
<title>Countdown</title>
<script type="text/javascript">
// set minutes
var mins = 3;

// calculate the seconds (don't change this! unless time progresses at a different speed for you...)
var secs = mins * 60;
function countdown() {
setTimeout('Decrement()',1000);
}
function Decrement() {
if (document.getElementById) {
minutes = document.getElementById("minutes");
seconds = document.getElementById("seconds");
// if less than a minute remaining
if (seconds < 59) {
seconds.value = secs;
} else {
minutes.value = getminutes();
seconds.value = getseconds();
}
secs--;
setTimeout('Decrement()',1000);
}
}
function getminutes() {
// minutes is seconds divided by 60, rounded down
mins = Math.floor(secs / 60);
return mins;
}
function getseconds() {
// take mins remaining (as seconds) away from total seconds remaining
return secs-Math.round(mins *60);
}
</script>
</head>
<body>

<div id="timer">
This is only valid for the next <input id="minutes" type="text" style="width: 14px; border: none; background-color:none; font-size: 16px; font-weight: bold;"> minutes and <input id="seconds" type="text" style="width: 26px; border: none; background-color:none; font-size: 16px; font-weight: bold;"> seconds.
</div>
<script>
countdown();
</script>

You’re looking for Set Interval

and… maybe? Clear Interval

…or if you want to keep the same code you have above, you could check for if(secs == 0) then reset back to secs = mins * 60

Thank u for your help.
Problem is resolved earlier :grinning:
