289. setInterval sets up a recurring timer. It returns a handle that you can pass into clearInterval to stop it from firing: var handle = setInterval(drawAll, 20); // When you want to cancel it: clearInterval(handle); handle = 0; // I just do this so I know I've cleared the interval. On browsers, the handle is guaranteed to be a number that isn ...

Pass it to the function clearInterval and you're safe: Code: Always store the returned number of setInterval in a variable, so that you can stop the interval later on: const intervalID = setInterval(f, 1000); // Some code. clearInterval(intervalID); (Think of this number as the ID of a setInterval.
Oct 5, 2017 · Ok, first of all, you need to be aware that your setInterval call is missing a parameter because the call is of the form : setInterval(func, delay, [param1, param2, ...]);. Second of all, if your problem is that you are not able to clear the interval, then you need to paste the code for the user object and whichever code is modifying your intervalid object.
You cannot PAUSE the setInterval function, you can either STOP it (clearInterval), or let it run. The solution I provided was a solution for OP's problem, I did not claim it worked in every possible scenario. That didn't solve his problem. The results would still be probabilistic.
Nov 25, 2009 · 5. just call clearInterval(intervalName), for example: var helloEverySecond = setInterval(function() { console.log("hello");}, 1000); can be stopped by clearInterval(helloEverySecond); – Rani Kheir. Jan 1, 2017 at 4:28. 22. This is a whole new level of ugly from Javascript.
552. setTimeout(expression, timeout); runs the code/function once after the timeout. setInterval(expression, timeout); runs the code/function repeatedly, with the length of the timeout between each repeat. Example: var intervalID = setInterval(alert, 1000); // Will alert every second. // clearInterval(intervalID); // Will clear the timer.
Alternately if you wanted to just have something happen at start and then forever at a specific interval you could just call it at the same time as the setInterval. For example: var this = function(){ //do } setInterval(function(){ this() },3600000) this() Here we have this run the first time and then every hour.
function myFn() {console.log('idle');} var myTimer = setInterval(myFn, 4000); // Then, later at some future time, // to restart a new 4 second interval starting at this exact moment in time. clearInterval(myTimer); myTimer = setInterval(myFn, 4000); You could also use a little timer object that offers a reset feature: function Timer(fn, t ...
@Alnitak, right because that is the only thing bad about setInterval. sigh. How about the fact that if the elements get removed, setInterval will keep causing errors unless you do some redundant defensive code. sigh. –
