How to clearInterval with unknown ID?

Question

Say someone (evil) has set us a timer with setInterval, but we don\'t know its ID (we don\'t have the reference to the object, that setInterval is returning, no

Answer 1

Well, empirically trials in Chrome show that setInterval returns a number which increments for each call. So if you are SURE that you setInterval was the last one set the following would work :

function clearLastInterval () {
  var i = setInterval (function () {}, 10000);
  clearInterval (i-1);
  clearInterval (i);
}

I'm not sure I would recommend this though ;-)
