    <h1>UPDATE 2:</h1> <p>Here is a working example using $.Deferred:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; $(document).ready(function () { $.Deferred(function (defer) { var i; var duration = 1000; var pipe = function(defer, index, duration) { return defer.pipe(function () { return $(".elem[order='" + index + "']").animate({opacity: 0}, duration); }); }; defer.resolve(); for (i = 0; i &lt; 5; i++) { defer = pipe(defer, i, duration); } defer.done(function () { console.log("Done, removing all .elem"); $(".elem").remove(); }); }); }); &lt;/script&gt; &lt;style type="text/css"&gt; body { padding: 20px; } .elem { border: 1px solid #000; padding: 10px; opacity: 1.0; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="elem" order="0"&gt;elem 0&lt;/div&gt; &lt;div class="elem" order="1"&gt;elem 1&lt;/div&gt; &lt;div class="elem" order="2"&gt;elem 2&lt;/div&gt; &lt;div class="elem" order="3"&gt;elem 3&lt;/div&gt; &lt;div class="elem" order="4"&gt;elem 4&lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <hr> <h2>UPDATE 1, BASED ON NEWLY INTRODUCED DELAY</h2> <p>To answer your comment below, I think your best bet is to simply fire off the callback on the animation that fires last. Since you're in full control of deciding duration (i.e. it's not a randomly generated duration), then you could compute what the last duration will be and use that to decide if it will be the correct iteration in which to fire the callback:</p> <pre><code>var i, callback, delay; var onComplete = function () { console.log("Animations complete!"); }; for (i = 0; i &lt; somevalue; i++) { delay = i * duration; callback = delay === ((somevalue - 1) * duration) ? onComplete : $.noop; //callback = i === somevalue - 1 ? onComplete : $.noop; //this can work too but doesn't check duration $(".elem[order='" + i + "']").delay(delay).animate({opacity:0}, duration, callback); } </code></pre> <hr> <h3>ORIGINAL ANSWER</h3> <p>It looks like you want all of these elements to start animating at the same time, and have the same duration. Based on this, I would suggest doing a single animate call, and modifying your approach to gathering the collection of elements.</p> <p>Example:</p> <pre><code>var i, elements, selector; for (i = 0; i &lt; somevalue; i++) { selector = ".elem[order='" + i + "']"; if (i === 0) { // Start the collection up with the first element elements = $(selector); } else { // Append element to the collection elements.add(selector); } } // Fire up the animation on all elements elements.animate({opacity:0}, duration, function () { console.log("Animation complete!"); }); </code></pre> <p><em>I haven't actually ran this code, but I'm pretty confident it should work.</em></p>

    1. COI added a .delay() to the first code in the question while you were writing this I guess. The animations may vary btw.

    2. COsorry for the late answer, but I'm currently doing this with `if(i==somevalue-1) oncomplete();` in the callback function without questioning the delay. (and assuming the last loop's element is animating at last and it is the last one to execute the callback). I was asking how to use jQuery Deferred's in situations like this. Thank you for your effort though.

    3. COAh yes, I see I pretty much looped back to your own solution... Stay tuned for an attempt at solving it with $.Deferred

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
