Stop setInterval call

03/27/2020 00:00:02

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?

I want the user to be able to stop the repeated refresh of data.

setInterval() returns an interval ID, which you can pass to clearInterval():

var refreshIntervalId = setInterval(fname, 10000);

/* later */

See the docs for setInterval() and clearInterval().

If you set the return value of setInterval to a variable, you can use clearInterval to stop it.

var myTimer = setInterval(...);

You can set a new variable and have it incremented by ++ (count up one) every time it runs, then I use a conditional statement to end it:

var intervalId = null;
var varCounter = 0;
var varName = function(){
     if(varCounter <= 10) {
          /* your code goes here */
     } else {

     intervalId = setInterval(varName, 10000);

I hope that it helps and it is right.
