Equivalent Behaviour Of 'jquery.active' In Q

In my c# selenium webdriver tests I occasionally have to make use of: public void WaitForJQuery(TimeSpan timeout) { var wait = new WebDriverWait(driver, timeout); wait.Unti

Solution 1:

No, Q keeps track of each promise independantly so the only record it maintains is unhandled rejections (for error reporting purposes) It wouldn't be too hard to build something though:

var pending = 0;
functionregister(operation) {
  pending++
  return Q(operation)
    .finally(function() { pending--; });
}

If you call register(promise) every time you create a promise, you'll get the result you're after by just testing whether pending === 0

This register method can also be used to check for pending jQuery promises (or any other type of promise that has a working then method) since Q will assimilate them.
