    <p>I'm close to this but cross-brained on something.</p> <p>I have this code:</p> <pre><code>var numOfLi = $('#myList li').length; var lastLi = numOfLi; $('.next').click(function() { var current = $('#myList').find('li.on'); current.removeClass('on'); current.next().addClass('on'); var grabAlt = $('.on img').attr('alt').split('|'); var holdAlt = grabAlt; $('#altStuff').html('&lt;ul class="altDescription"&gt;' + '&lt;li&gt;' + holdAlt[0] + '&lt;/li&gt;' + '&lt;li&gt;' + holdAlt[1] + '&lt;/li&gt;' + '&lt;li&gt;' + holdAlt[2] + '&lt;/li&gt;' + '&lt;/ul&gt;'); }); $('.prev').click(function() { var current = $('#myList').find('li.on'); current.removeClass('on'); current.prev().addClass('on'); var grabAlt = $('.on img').attr('alt').split('|'); var holdAlt = grabAlt; $('#altStuff').html('&lt;ul class="altDescription"&gt;' + '&lt;li&gt;' + holdAlt[0] + '&lt;/li&gt;' + '&lt;li&gt;' + holdAlt[1] + '&lt;/li&gt;' + '&lt;li&gt;' + holdAlt[2] + '&lt;/li&gt;' + '&lt;/ul&gt;'); }); </code></pre> <p>It clicks forward and back through a list of Li's, assigns a class of 'on' to the li, grabs the alt text of the image in each Li, parses that and puts it into a paragraph.</p> <p>This all works great and dynamically, but now I'm trying to stop the next/prev buttons when they reach the first/last li.</p> <p>My thought is to: 1. upon clicking, check to see if the current li is the first one (don't let prev work) or the last one (don't let next work).</p> <p>But, I'm a little mushed now as to how to check that. The .length only returns the count....so, how can I get the position value of whatever the current li is?</p> <p>I was thinking I have to put all the li's of this ul into a matrix and then just check against it's index but I'm not getting that work.</p> <p>Thanks for looking.</p> <p>I was thinking I'd have to put the entire UL list into </p>

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.
