    <p>I use the following code to check whether or not a certain div exists. And if it doesn't it adds it to the dom in the proper place.</p> <pre><code>if (!($("#col"+lastSlide).length)) { $('#schDisplay').prepend('&lt;div id="col' + (lastSlide) + '"&gt;&lt;/div&gt;'); } </code></pre> <p>My problem is that when this if statement checks again for a div that had already once been appended/prepended, it doesn't see the div that I added. So it will continue to add the div that was already prepended/appended.</p> <p>Is there any way this issue can be fixed?</p> <p>more code:</p> <pre><code>//fillin added column function fillElement(colnum) { var URL = 'schedule.php'; $("#col"+colnum).text("Loading...").show(); $.post(URL,{fecolnum: colnum}, function (data) { $("#col"+colnum).html(data).show(); }); } //...irrelevant code... // Create event listeners for .arrows clicks $('.arrows') .bind('click', function(){ numberOfSlides++; // Determine new position if ($(this).attr('id')=='arrow_right') { lastSlide++; currentPosition++; if (!($("#col"+lastSlide).length)) { $('#schDisplay').append('&lt;div id="col' + lastSlide + '" class="schColumn" style="float: left; width: ' +slideWidth+ 'px"&gt;&lt;/div&gt;'); fillElement(lastSlide); } } else { lastSlide--; currentPosition--; if (!($("#col"+lastSlide-2).length)) { $('#schDisplay').prepend('&lt;div id="col' + (lastSlide-2) + '" class="schColumn" style="float: left; width: ' +slideWidth+ 'px"&gt;&lt;/div&gt;'); fillElement(lastSlide-2); } } </code></pre>

    1. COYou need to show more context. I cannot tell from your question how '#col'+lastSlide and '#schDisplay' are related. From what you've shown me, it's entirely possible that '#col'+lastSlide doesn't change when you prepend to #schDisplay.

    3. COI updated the question and added more code. I have the feeling that I may need to use .live() somewhere, but i'm not sure where or what the proper syntax would be.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
