[MDN](https://developer.mozilla.org/en-US/docs/DOM/window.setInterval) is a really good JS reference if you're not sure how a particular function works. — nnnnnn, Feb 03 '13 at 12:24

When you start the interval it returns an integer defining it:

var timer = window.setInterval( ... );

You can then clear that interval when your AJAX function returns true:

...
success: function(response) {
  console.log(response);
  if (response['status'] != 'ok') {
    clearInterval(timer);
    return;
  }
}
...

the setInterval() method will return an integer/number. You need to store this, then pass it to the method clearInterval() to stop it.

var intervalId = window.setInterval(.....);

then later, when you want to stop it, I think it would go:

window.clearInterval(intervalId);

setInterval() returns a handle which you can later pass to window.clearInterval() to stop the timer.
