    <p>I'm writing a small Chrome extension to manipulate Google's search results' DOM to add a small set of questions to ask the user why s/he chose to follow that link; while polishing, I decided to look around the page in case there was an old poll already shown, to remove it (as in, if the user decided to follow another result after s/he clicked on one), and that's when I started noticing a weird behaviour: the first time I clicked a link I got presented the poll before being able to proceed to the chosen page; the second time (without leaving the page) the old poll got correctly removed and the new one added to the DOM, but this new element got targeted by <code>slideDown()</code> only if it was inserted <em>before</em> the old one (i.e. if I clicked a link <em>above</em> the previous one).</p> <pre><code>$('li.g a') // all the results' link .bind('click', function(event) { event.preventDefault(); // avoid going to destination right away var oldpoll = $('#extension'); if (oldpoll.length) oldpoll.slideUp('fast', function(){ $(this).remove(); }); // remove (eventual) old poll ... $(this).parents('.g').append(element); $('#extension').slideDown(); }); </code></pre> <p>As you can see, I figured there was some sort of caching going on and tried to "force" avoiding it by declaring a variable to hold the old element, but that didn't work; eventually, I managed to sail around it by forcing a new DOM traversal with <code>$('#extension a').parent().slideDown();</code>, but now I'm really curious about whether it's my fault, or Chrome's, or JQuery's. Thanks.</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.
