    <p>Alright so I recently received this project from a client. They needed a offline and online website that could be loaded via usb drive onto ipads or remote sources with no internet connection. So all of the files had to be ".html" extension. In order to make maintenance and changes easier I used javascript to load global portions of content into the pages, specifically the nav. I am having trouble trying to find the new elements I've added, here is a sample of the nav.tpl I'm loading via ajax into the dom:</p> <pre><code> &lt;li&gt;&lt;a href="index.html" class="nav-grey"&gt;&lt;span class="spacer"&gt;&lt;/span&gt;HOME&lt;span class="spacer"&gt;&lt;/span&gt;&lt;/a&gt;&lt;/li&gt; &lt;li class="dropdown"&gt; &lt;a href="unmatched_simplicity.html" class="nav-red"&gt;unmatched &lt;br/&gt; SIMPLICITY&lt;/a&gt; &lt;ul class="dropdown-menu"&gt; &lt;li&gt;&lt;a href="unmatched_simplicity-easy_to_use.html"&gt;Easy to Use&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="unmatched_simplicity-cashier_workstation.html"&gt;Cashier Workstation Screen&lt;/a&gt;&lt;/li&gt; &lt;li class="dropdown-submenu"&gt; &lt;a tabindex="-1" href="unmatched_simplicity-fuel.html"&gt;Fuel&lt;/a&gt; &lt;ul class="dropdown-menu"&gt; &lt;li&gt;&lt;a tabindex="-1" href="unmatched_simplicity-fuel-authorize_pump.html"&gt;Authorize Pump&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a tabindex="-1" href="unmatched_simplicity-fuel-all_stop.html"&gt;All Stop&lt;/a&gt;&lt;/li&gt; </code></pre> <p>Here is the javascript:</p> <p>$.get( "lib/nav.tpl", function( navItems ) { $( ".nav" ).html( navItems ); });</p> <p>Now I have a naming convention I am using for organizational purposes as well as bread crumbs and now I am trying to use it to detect the nav item that the current page is on. Basically each level of pages is separated by "-". My goal was to use the url to find the anchor with href = to the current page, then go to its parent "li" and add the active class ".active". This is what I have:</p> <pre><code>( function( window ) { var location = locationTiers = ''; location = window.location.pathname; location = location.substr( location.indexOf('/') + 1 ); location = location.replace('.html', ''); locationTiers = location.split('-'); console.log( $( 'a[href="'+ locationTiers[0] +'.html"]' ).parent('li') ); }) ( window ); </code></pre> <p>It's strange because I can find the anchor if I remove ".parent('li')", but with the ".parent('li')" it returns empty. It seems like if it couldn't find the "li" it wouldn't be able to find the "a". I know about the .on() subsitute for live but this is mostly for detecting events. </p> <p>I was hoping I could do something like this:</p> <pre><code>$('body','a[href="'+ locationTiers[0] +'.html"]').parent('li') </code></pre> <p>Similar to .on live method but this doesn't work either. If anyone can help me figure out how I can find this dynamically added item it would be greatly appreciated!</p> <p>Thanks</p>

    1. COthe problem could be that the location code is getting executed before the navigation items are loaded into the page

    2. COcan you change the console to `console.log( $( 'a[href="'+ locationTiers[0] +'.html"]' ).parent().get() );` and see what element is returned

    3. CO@ArunPJohny I'm pretty sure that's happening, I'm just not sure what to load events after certain actions have fired.

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.
