Use a closure around a counter variable.

<pre><code>var $blocks = $('.block');
var count = $blocks.length;
$blocks.each(function(i){
 $(this).stop().delay(60 * i).animate({
 'opacity': 1
 }, {
 duration: 250,
 complete: function() {
 if (--count == 0) {
 // All animations are done here!
 mycallbackfunction();
 }
 }
 });
});
</code></pre>

Note the saving of the list of items into the $block variable to save a lookup.

<a href="http://www.elfsternberg.com/2011/02/14/jquery-fadeout-lot-fadein-deferred-promises-jqueryanimate/" rel="nofollow">Felix Kling's answer</a> will fire the callback when there's no animation left to do. This makes the callback firing even if the animation is stopped via <code>$el.stop()</code> and thus not completed to the end.

I found an <a href="http://www.elfsternberg.com/2011/02/14/jquery-fadeout-lot-fadein-deferred-promises-jqueryanimate/" rel="nofollow">method by Elf Sternberg</a> using deferred objects which I implemented in this jsfiddle:

<a href="http://jsfiddle.net/8v6nZ/" rel="nofollow">http://jsfiddle.net/8v6nZ/</a>

I'm trying to animate a set of elements simultaneously (almost, there's a small delay between each animation):

<pre><code>$('.block').each(function(i){
 $(this).stop().delay(60 * i).animate({
 'opacity': 1
 }, {
 duration: 250,
 complete: mycallbackfunction // &lt;- this fires the callback on each animation :(
 });
});
</code></pre>

How can I run a callback function after all animations have completed?

我正在尝试同时动画一组元素(几乎，每个动画之间有一个小延迟)：$('.block').each(function(i){   $(this).stop().delay(60 * i).animate({     'opacity': 1   }, {      duration: 250,      complete:...
