Question

My Jquery:

function myTimer() {
    var sec = 15
    var timer = setInterval(function() { 
    $('#timer').text(sec--);
    if (sec == -1) {
      clearInterval(timer);
      alert('done');
     } 
    }   , 1000);

}

$("#knap").click(function() {
    myTimer();
});

$("#reset").click(function() {
// set timer to 15 sec again.. 
});

I want the timer to be reset when clicked on #reset.

You need to leave your “timer” variable in a scope that is available the next time you call the myTimer function so you can clear the existing interval and reset it with a new interval. Try:

var timer;
functionn myTimer() {
    var sec = 15
    clearInterval(timer);
    timer = setInterval(function() { 
    $('#timer').text(sec--);
    if (sec == -1) {
      clearInterval(timer);
      alert('done');
     } 
    }   , 1000);

}

$("#knap").click(function() {
    myTimer();
});

$("#reset").click(function() {
   myTimer();
});
