jquery deffered with a random number of animations

I've got x number of animations running on a random timer. I also have code that needs to run after all the animations are complete.

I thought to use deferred, but it doesn't seem to be running the way I hoped it was going to. Here's a link (you may have to run it a few times for it to not work):

http://jsfiddle.net/N8nFU/

Code:

var callback = function() {
    alert('done!');
};

var animations;
for (var i = 0; i < $('div').length; i++) {
    var random = Math.random() * (800 - 100) + 100;
    animations = $('div').eq(i).slideUp(random);
}

$.when(animations).done(callback);

Any suggestions on how to wait for the callback to be called once all the animations are complete?

You are always overriding the animations variable. So the object you pass to $.when will be the one from the last iteration.

Add them to an array and call $.when with that array:

var animations = [];
for (var i = 0; i < $('div').length; i++) {
    var random = Math.random() * (800 - 100) + 100;
    animations.push($('div').eq(i).slideUp(random));
}

$.when.apply($, animations).done(callback);
