Detecting If Anything On The Page Is Being Animated

I know about the :animated selector, but currently am running into (what might be one of a few) performance issue for older IE's (go figure). I feel like it might potentially be th

Solution 1:

All jQuery animation timers are stored in the array $.timers. One option is just to check whether length of $.timers property is more than zero:

if ($.timers.length > 0) {
    // something is animating
}

Solution 2:

I think it would be more efficient to push your element to an array when the animation starts, and remove it from the array when it's done animating. Or better yet, increment a variable on animation start, and decrease it by 1, when it's done. If the variable is 0, no animation should currently be running.

So, some pseudocode:

var animatingElements = 0;

functionanimationStart(){ // Add this function in your animation start events;
    animatingElements++;
}

functionanimationEnd(){ // Add this function  in your animation end events;
    animatingElements--;
}

if (animatingElements === 0) {
    clearInterval(testAnimationInterval);
}

This is, assuming you have access to the code that starts / catches the end of your animations, of course.
