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 us

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) {
          varCounter++;
          /* your code goes here */
     } else {
          clearInterval(intervalId);
     }
};

$(document).ready(function(){
     intervalId = setInterval(varName, 10000);
});

I hope that it helps and it is right.

Declare variable to assign value returned from setInterval(...) and pass the assigned variable to clearInterval();

e.g.

var timer, intervalInSec = 2;

timer = setInterval(func, intervalInSec*1000, 30 ); // third parameter is argument to called function 'func'

function func(param){
   console.log(param);
}

// Anywhere you've access to timer declared above call clearInterval

$('.htmlelement').click( function(){  // any event you want

       clearInterval(timer);// Stops or does the work
});

I guess the following code will help:
```
var refreshIntervalId = setInterval(fname, 10000);

clearInterval(refreshIntervalId);
```
You did the code 100% correct... So... What's the problem? Or it's a tutorial...

Use setTimeOut to stop the interval after some time.

var interVal = setInterval(function(){console.log("Running")  }, 1000);
 setTimeout(function (argument) {
    clearInterval(interVal);
 },10000);

This is how I used clearInterval() method to stop the timer after 10 seconds.

function startCountDown() {
  var countdownNumberEl = document.getElementById('countdown-number');
  var countdown = 10;
  const interval = setInterval(() => {
    countdown = --countdown <= 0 ? 10 : countdown;
    countdownNumberEl.textContent = countdown;
    if (countdown == 1) {
      clearInterval(interval);
    }
  }, 1000)
}

<head>
  <body>
    <button id="countdown-number" onclick="startCountDown();">Show Time </button>
  </body>
</head>

setInterval() returns an interval ID, which you can pass to clearInterval():
```
var refreshIntervalId = setInterval(fname, 10000);

/* later */
clearInterval(refreshIntervalId);
```
See the docs for setInterval() and clearInterval().
