The ID value returned by setTimeout() is used as the parameter for the clearTimeout() method.

<html>
<head>
<script>
var c=0;
var t;
var timer_is_on=0;

function timedCount()
{
document.getElementById('txt').value=c;
c=c+1;
t=setTimeout(function(){timedCount()},1000);
}

function doTimer()
{
if (!timer_is_on)
    {
    timer_is_on=1;
    timedCount();
    }
}

function stopCount()
{
clearTimeout(t);
timer_is_on=0;
}
</script>
</head>
<body>

<form>
<input type="button" value="Start count!" onclick="doTimer()">
<input type="text" id="txt">
