    <p><a href="http://www.malsup.com/jquery/block/#options" rel="nofollow">jQuery BlockUI</a> plugin has a very cool feature of attaching itself to every AJAX call with simple code:</p> <pre><code>$(document).ajaxStart($.blockUI).ajaxStop($.unblockUI); </code></pre> <p>Can I use similar approach to display blockUI overlay on each navigation, like clicking any link etc.?</p> <p>I think, this should be done using <code>unload</code> event, but I failed with this.</p> <pre><code>$(window).on('unload', function() { $.blockUI; }); </code></pre> <p>Upon navigation blockUI overlay does not appears (I don't care about hiding it, because new loaded page won't have it).</p> <p>I can even:</p> <pre><code>$(window).on('unload', function() { console.log('$.blockUI;'); $.blockUI; console.log('Bye!'); }); </code></pre> <p>and I clearly see both <code>$.blockUI;</code> and <code>Bye!</code> messages in console, but no sign of blockUI overlay.</p> <p>I've read that many browsers blocks displaying <code>alert()</code>'s in <code>unload</code>. Does it also covers blockUI? It shouldn't as it is just a bunch of divs or other DOM elements plus some styling?</p> <p>Tested in Chrome 27, Internet Explorer 10 and Firefox 21. What am I missing or doing wrong?</p> <p>Two or three years ago, in an old project, I manage to achieve above mentioned functionality, but it was done there purely by biding blockUI showup to particular buttons and menu items. I would like to avoid this as much as possible and make it globally, just as with AJAX calls.</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.
