    <p>I'll note that this code is not something I built, I'm simply making some UI changes using a plugin on a system that's already in place.</p> <p>I'm building a plugin that's utilizing <a href="http://www.malsup.com/jquery/block/" rel="nofollow">blockUI</a> (yes, I need to build a plugin with a plugin) in order to display a loading icon over certain elements when an Ajax call is fired, however this one in particular calls an <code>alert()</code> if the <code>success()</code> event doesn't get the response it needs.</p> <p>The result of this is my loading icon calling <code>fadeOut()</code> <em>after</em> the <code>alert</code> fires, which is not what I want it to do.</p> <p>When I call the function I'm building, I pass in <code>$.post()</code> complete with the settings and options I need, like this:</p> <pre><code>$.fn.startLoading({ element: $("div"), ajax: $.post('some.url', { //Ajax settings... }, function (response) { //This is the success function, right? if (good) { //stuff } else alert("Bad!"); //This happens BEFORE fadeOut() } }, 'text') .error(function (msg) { alert('Worse error!'); }) }); </code></pre> <p>My plugin's function takes all of this in as one <code>options</code> parameter, like so:</p> <p><code>$.fn.startLoading = function (options) { ...</code></p> <p>I then access the <code>$.post()</code> call like this:</p> <pre><code>if (options.ajax) ajax = options.ajax; </code></pre> <p>This is where I'm stuck. I need to make sure that the <code>fadeOut()</code> happens before the <code>success</code> event is fired. How can I do this using the <code>ajax</code> variable I've created in my plugin?</p>

    1. COSyntax error here: `ajax: $.post('some.url'),{` should probably remove `)`

    3. COAlso, `jqXHR.error` is depreciated, you should use .fail instead.

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.

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