Javascript setInterval function to clear itself?

Question

myInterval = setInterval(function(){
     MyFunction();
},50);

function MyFunction()
{
    //Can I call clearInterval(myInterval); in here?
}

The

Answer 1

clearInterval(myInterval);

will do the trick to cancel the Interval whenever you need it. If you want to immediately cancel after the first call, you should take setTimeout instead. And sure you can call it in the Interval function itself.

var myInterval = setInterval(function() {
  if (/* condition here */){
        clearInterval(myInterval);
   } 
}, 50);
