    <p>I have a slider (flexslider) that dynamically adds the class "flex-active-slide" to the active <code>&lt;li&gt;</code>. </p> <p>I want to use jQuery to do something when a specific slide has the class "flex-active-slide." I tried the following, but it doesn't work because the .flex-active-class is added on the fly after this has already run:</p> <pre><code>if ( $('#slider li.about').is('.flex-active-slide') ){ $('.nav li.about').show(); } </code></pre> <p>In my research, it seems I want to use on(), but all the examples I see relate it to an event like click() or hover(). This isn't triggered by anything like that -- the class just "appears." I can't figure out how to format it. Something like this...?</p> <pre><code>$(document).on('???',".flex-active-slide", function() { $(".nav li.about").show();; }) </code></pre> <p>I'm sure that is embarrassingly incorrect... I appreciate any help you can give!!</p> <p>Note: I can't simply use CSS because the .nav I'm trying to affect is completely unrelated to the slider div.</p> <p>UPDATE: Here is what appears to be the code in the flexslider.js that controls adding the flex-active-slide class. Is there anything here that suggests anything I could do?</p> <pre><code> slider.flexAnimate = function(target, pause, override, withSync, fromNav) { if (asNav &amp;&amp; slider.pagingCount === 1) slider.direction = (slider.currentItem &lt; target) ? "next" : "prev"; if (!slider.animating &amp;&amp; (slider.canAdvance(target, fromNav) || override) &amp;&amp; slider.is(":visible")) { if (asNav &amp;&amp; withSync) { var master = $(vars.asNavFor).data('flexslider'); slider.atEnd = target === 0 || target === slider.count - 1; master.flexAnimate(target, true, false, true, fromNav); slider.direction = (slider.currentItem &lt; target) ? "next" : "prev"; master.direction = slider.direction; if (Math.ceil((target + 1)/slider.visible) - 1 !== slider.currentSlide &amp;&amp; target !== 0) { slider.currentItem = target; slider.slides.removeClass(namespace + "active-slide").eq(target).addClass(namespace + "active-slide"); target = Math.floor(target/slider.visible); } else { slider.currentItem = target; slider.slides.removeClass(namespace + "active-slide").eq(target).addClass(namespace + "active-slide"); return false; } } ... </code></pre>

    1. COYou want something to happen automatically at the time the class is added? AFAIK, there's no way to do that. Check the documentation for flexslider to see if it offers its own handlers that you can bind to certain actions.

    2. COI've updated to include what appears to be the relevant section of the flexslider code... is there anything here that I can bind to?

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.
