    <p>I have some kind of strange behaviour using jQuery's Click-Function. I also tried it with the on-EventHandler. There is some simple markup from Twitter's Bootstrap Navbar and I'm trying to change the CSS-Class of an li-tag. In this case I want to remove the CSS-Class active and add it to the currently clicked li-tag. But the change get's applied with a shift of one click. So when when e.g. 'Preview' is the current visual active element and I click on 'Document', the CSS-Class seems not to be changed. When I click afterwards on 'Slidecast', then the visual active element is 'Document' which is not the expected behavoiur. Next Click on 'Preview' and now 'Slidecast' is the visual active element. What I'm doing wrong? I tried it with remove and add and also with toggleClass, but that doesen't matter. Here is my code and markup. JS is wrapped into a Dom-Ready-Function.</p> <pre><code>&lt;div class="navbar"&gt; &lt;div class="navbar-inner"&gt; &lt;ul class="nav"&gt; &lt;li class="active"&gt;&lt;a href="#!document_defaultview"&gt;Document&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#!document_slidecast"&gt;Slidecast&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#!document_preview"&gt;Preview&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#!document_notes"&gt;Notes&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#!document_questions"&gt;Questions&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#!document_activities"&gt;Activities&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>JS</p> <pre><code>$("#document_navbar a").on('click', function(e) { // Hide all content, display the one related to hash-tag $(".document_view").toggle(false); $(app_locationToId($(this).attr("href"))).toggle(true); // Here is the part that does not work: //$("#document_navbar li.active").removeClass("active"); //$("a[href='" + window.location.hash + "']").parent().addClass('active'); // Another try ... same result as described above! $("#document_navbar li.active").toggleClass("active", false); $("a[href='" + window.location.hash + "']").parent().toggleClass("active", true); }); </code></pre> <p>OK according to your answers, here is the code I've used to handle that problem: </p> <pre><code>$("#document_navbar a").on('click', function(e) { new_location = app_locationToId($(this).attr("href")); // Hide all content, display the one related to hash-tag $(".document_view").toggle(false); $(new_location).toggle(true); // Change visual active li-tag $("#document_navbar li.active").toggleClass("active", false); $("a[href='" + app_IdToLocation(new_location) + "']").parent().toggleClass("active", true); }); </code></pre>

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.
