How to reset timeout in Javascript/jQuery?

Question

I\'ve got a field A in my webpage which, when edited by the user, invokes an API call (using jQuery), which updates field B. After the edit, the API should be called every 1

Answer 1

var update;

// something happened

clearTimeout(update);
update = setTimeout(thisFunction, 10000);

Answer 2

A timer can be cancelled with clearTimeout, so:

var timer = null;
if (timer) {
    clearTimeout(timer); //cancel the previous timer.
    timer = null;
}
timer = setTimeout(thisFunction, 10000);
