Question

I need to call a function that updates some JS objects on the page every 2 minutes.
How would I do that?

I created a onload function and a countdown function that refreshes a whole page and therefore resets the timer until next page refresh, but this is not the way I want it. Is there a way to keep an infinite time loop?

I assume, if I could create a an infinite loop and do something like this:

if (currentSeconds%120==0){ 
callFunction();
}

Answer 1

setInterval(callFunction, 120000);
