Stop setInterval call in JavaScript

Question

I am using setInterval(fname, 10000); to call a function every 10 seconds in JavaScript. Is it possible to stop calling it on some event?

Answer 1

var keepGoing = true;
setInterval(function () {
     if (keepGoing) {
        //DO YOUR STUFF HERE            
        console.log(i);
     }
     //YOU CAN CHANGE 'keepGoing' HERE
  }, 500);

You can also stop the interval by adding an event listener to let's say a button with the ID "stop-interval":

$('buuton#stop-interval').click(function(){
   keepGoing = false;
});

HTML:

Stop Interval

Note: The interval will still be executed, nothing will happen though.
