    <p>if you wanted to actually target the current <code>&lt;a&gt;</code> generically out of many <code>&lt;a&gt;</code>'s when selecting an anchor, use the <code>event</code> that's passed through on <code>.on('click</code>)`:</p> <pre><code>&lt;a data-example="test-london"&gt;London&lt;/a&gt; &lt;a data-example="test-rome"&gt;Rome&lt;/a&gt; &lt;a data-example="test-paris"&gt;Paris&lt;/a&gt; &lt;script type="text/javascript"&gt; $(document).on('click', 'a', function( event ) { alert( $(event.target).attr( 'data-example' )); }); &lt;/script&gt; </code></pre> <p><strong>Fiffle</strong>: <strong><a href="http://jsfiddle.net/hM4kC/" rel="nofollow noreferrer">http://jsfiddle.net/hM4kC/</a></strong></p> <p>Although, I wouldn't suggest this at all normally. As this just an example on how you would pick the <em>selected</em> <code>&lt;a&gt;</code> anchor out of an jQuery object which is retrived from many results (for example, the current page would collect 138 Nodes! Which is an <em>expensive</em> operation, see below:)</p> <p><img src="https://i.stack.imgur.com/bY6kr.jpg" alt="enter image description here"></p> <p>It's much quicker, cleaner &amp; semantic to stick to selecting by classes or ID, so in your case:</p> <pre><code>&lt;a data-bookmark-item="2" data-userid="501" class="getbook"&gt;John Grisham&lt;/a&gt; &lt;a data-bookmark-item="3" data-userid="551" class="getbook"&gt;J.K Rowling&lt;/a&gt; &lt;a data-bookmark-item="4" data-userid="201" class="getbook"&gt;JRR Tolkien&lt;/a&gt; &lt;script type="text/javascript"&gt; $(document).on('click', '.getbook', function() { var bookMark = $(this).data('bookmark-item'), userid = $(this).data('userid'); console.log( bookMark + ' for user: '+ userId ); somefunction( bookMark, userId ); //Pass them through to where needed. }); &lt;/script&gt; </code></pre> <p>Where as you'd replace <code>bookmark-item="4"</code> with <code>bookmark-item="&lt;?=$item_id;?&gt;"</code> and utilising jQuery's <a href="http://api.jquery.com/jQuery.data/" rel="nofollow noreferrer"><code>.data()</code></a> to collect relevant DOM information.</p> <p><strong>Fiddle:</strong> <a href="http://jsfiddle.net/N99B6/3/" rel="nofollow noreferrer">http://jsfiddle.net/N99B6/3/</a></p>

    3. CO@JohnBrunner Oh! Sorry! Well, then I guess the question is about collecting info with `$(this)` then, I'd use `.data()` or `.attr()` - Apolgoies for that =)

Querying!

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).
