I was wondering how can I stop a timer after ten seconds in javascript using setInterval and clearInterval?? Here's my code example, could you please tell me where I'm going wrong:
<!DOCTYPE html>
<html>
<head>
<script>
var tt=setInterval(function(){startTime()},1000);
function startTime()
{
var today = new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
// add a zero in front of numbers<10
m=checkTime(m);
s=checkTime(s);
today=checkTime(today);
document.getElementById('txt').innerHTML=s;
}
function checkTime(tt)
{
if (tt==10)
{
tt="0" + tt;
console.log(tt);
clearInterval(tt);
}
return tt;
}
</script>
</head>
<body onload="startTime()">
<div id="txt"></div>
</body>
</html>

you can set timeout on clear like this right after you set the interval:
var tt = setInterval(function(){ startTime() }, 1000);
setTimeout(function() { clearInterval(tt); }, 10000);
Since startTime() will run every second, make a counter to increment to 10 inside of it, then clear the interval.
var tt=setInterval(function(){startTime()},1000);
var counter = 1;
function startTime()
{
if(counter == 10) {
clearInterval(tt);
} else {
counter++;
}
document.getElementById('txt').innerHTML= counter;
}
