    <p>I've put some code together which partially works and throws up no errors in Firebug.</p> <pre><code>jQuery( document ).ready( function( $ ) { var i = jQuery('[name="reference[]"]').size() + 1; jQuery('a#add_reference').click(function() { input_code = '&lt;div class="reference"&gt;' + '&lt;input type="hidden" value="" name="reference[]" /&gt;' + '&lt;h3&gt;Reference #' + i + '&lt;/h3&gt;' + '&lt;div class="line double"&gt;' + '&lt;label&gt;Author(s)&lt;/label&gt; &lt;input type="text" name="ref_authors" /&gt;' + '&lt;label&gt;Publisher&lt;/label&gt; &lt;input type="text" name="ref_publisher" /&gt;' + '&lt;/div&gt;' + '&lt;div class="line double"&gt;' + '&lt;label&gt;Publication Year&lt;/label&gt; &lt;input type="text" name="ref_pub_year" /&gt;' + '&lt;label&gt;Page Number(s)&lt;/label&gt; &lt;input type="text" name="ref_page_nums" /&gt;' + '&lt;/div&gt;' + '&lt;div class="line"&gt;&lt;label&gt;Document Title&lt;/label&gt; &lt;input type="text" name="ref_doc_title" /&gt;&lt;/div&gt;' + '&lt;div style="clear:both;"&gt;&amp;nbsp;&lt;/div&gt;' + '&lt;p&gt;Click &lt;a href="javascript:void(0);" id="' + i + '_del_reference"&gt;here&lt;/a&gt; to remove Reference #' + i + '.&lt;/p&gt;' + '&lt;/div&gt;'; jQuery(input_code).appendTo('#references_wrapper'); i++; }); jQuery('[id="' + i + '_del_reference"]').click(removeBox); jQuery('[id="1_del_reference"]').click(removeBox); var removeBox = function() { jQuery( this ).parents('div.reference').remove(); return false; }; }); </code></pre> <p>Which accompanies the HTML:</p> <pre><code>&lt;div id="references_wrapper"&gt; &lt;p&gt;Click &lt;a href="javascript:void(0);" id="add_reference"&gt;here&lt;/a&gt; to add a new reference.&lt;/p&gt; &lt;div class="reference"&gt; &lt;input type="hidden" value="" name="reference[]" /&gt; &lt;h3&gt;Reference #1&lt;/h3&gt; &lt;div class="line double"&gt; &lt;label&gt;Author(s)&lt;/label&gt; &lt;input type="text" name="ref_authors" /&gt; &lt;label&gt;Publisher&lt;/label&gt; &lt;input type="text" name="ref_publisher" /&gt; &lt;/div&gt; &lt;div class="line double"&gt; &lt;label&gt;Publication Year&lt;/label&gt; &lt;input type="text" name="ref_pub_year" /&gt; &lt;label&gt;Page Number(s)&lt;/label&gt; &lt;input type="text" name="ref_page_nums" /&gt; &lt;/div&gt; &lt;div class="line"&gt;&lt;label&gt;Document Title&lt;/label&gt; &lt;input type="text" name="ref_doc_title" /&gt;&lt;/div&gt; &lt;div style="clear:both;"&gt;&amp;nbsp;&lt;/div&gt; &lt;p&gt;Click &lt;a href="javascript:void(0);" id="1_del_reference"&gt;here&lt;/a&gt; to remove Reference #1.&lt;/p&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p><em>THE PROBLEM</em> is that I can add references but can't delete them.</p> <p>Could someone please point out where I've gone wrong? Frustrating thing is I've done this kind of thing a few times (with slightly different effects) and I still can't get it working!</p> <p>Thanks in advance.</p>

    1. COWhat is the problem? You haven't mentioned the expected behavior, and how that differs from what the code is actually doing.

    3. CObtw, for this kind of code where you're basically trying to do client side templating, try looking at jQuery tmpl: http://api.jquery.com/jquery.tmpl/

Guidance
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).
