Answer 1

Use setInterval and clearInterval for timer counting, setTimeout only run once.

Try this:

var count, countNumber;

function start(){
countNumber = 11;
count = setInterval(countTrigger, 1000);
}

function countTrigger(){
if(countNumber > 0){
countNumber-- ;
document.getElementById("arb").innerHTML = countNumber ;
}
}

function stop(){
clearTimeout(count);
}
