    <p><strong>RESOLVED: The line destination.block(...) is the one causing the errors. I've forcing empty to equal true to avoid this. I think that the if (empty) statement is just picking between two different ways of displaying a busy message.</strong></p> <p>I'm new to jQuery and have taken over maintaining an ASP.NET MVC 2 project from an ex-colleague. I'm struggling to understand what the following line of code is doing:</p> <pre><code>var empty = ($(":not(script)", destination).length == 0); </code></pre> <p>This line causes and error in IE but not in Firefox. To be honest looking at the function below I don't think it's needed, but as my colleague did not believe in commenting his code. I need to understand the impact of changing the code. The context for the above is the following Javascript function:</p> <pre><code>PRISMbase.LoadPartialEx = function(url, data, destination, successCallback, loadingMessage, appendNotOverwrite) { var empty = ($(":not(script)", destination).length == 0); var message = loadingMessage == null ? "Please wait" : loadingMessage; if (empty) destination.html(busy); else destination.block({ message: '&lt;h1 class="Progress"&gt;' + message + '&lt;/h1&gt;' }); return $.ajax({ data: data, dataType: "html", type: "GET", url: url, success: function(viewHtml) { var partial = $(viewHtml); if (!empty) destination.unblock(); if(viewHtml != "") { if (appendNotOverwrite) destination.append(partial); else destination.html(partial); PRISMbase.InitialiseFormElements(destination); } else destination.empty(); if (successCallback != null) successCallback(destination, partial); } }); } </code></pre> <p>In the above:</p> <p>destination = a jQuery selector returning "#TabContent" (this is a div).</p> <p>busy ='<code>&lt;img class="progress" src="/Content/OnyxProgressCircle.gif" /&gt;</code>';</p> <p>Any help would be appreciated.</p> <p>Thanks.</p> <p>Alan</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.
