    <p>I am working on the ode-to-food MVC4 demo app on Pluralsite by Scott Allen and have a troublesome error enabling ajax calls. I am thinking this may have something to do with my more recent jquery version but not sure.</p> <p>When I uncomment following line to activate ajax call I get the Microsoft JScript runtime error, otherwise it works fine:</p> <pre><code>$('form[data-ucw-ajax="true"]').submit(ajaxFormSubmit); </code></pre> <p><strong>The error is:</strong></p> <pre><code>Unhandled exception at line 4411, column 2 in http://localhost:17471/Scripts/jquery-1.9.0.js 0x800a139e - Microsoft JScript runtime error: Syntax error, unrecognized expression: &lt;div class="wrapper clearfix"&gt; .... &lt;/div&gt; &lt;hr /&gt; </code></pre> <p><strong>My View has this form:</strong></p> <pre><code>&lt;form method="get" action="@Url.Action("Index")" data-ucw-ajax="true" data-ucw-target="#facilitiesList"&gt; </code></pre> <p><strong>My JQuery code is:</strong></p> <pre><code>$(function () { var ajaxFormSubmit = function () { var $form = $(this); var options = { url: $form.attr('action'), type: $form.attr('method'), data: $form.serialize() }; $.ajax(options).done(function (data) { var $target = $($form.attr('data-ucw-target')); var $newHtml = $(data); $target.replaceWith($newHtml); $newHtml.effect('highlight'); }); return false; }; $('form[data-ucw-ajax="true"]').submit(ajaxFormSubmit); }); </code></pre> <p><strong>My Script Load Bundles look like:</strong></p> <pre><code>bundles.Add(new ScriptBundle("~/bundles/jquery/ucw").Include( "~/Scripts/jquery-{version}.js", "~/Scripts/jquery-ui-{version}.js", "~/Scripts/jquery.unobtrusive*", "~/Scripts/jquery.validate*", "~/Scripts/jquery-migrate-1.0.0.js", "~/Scripts/My.js" )); </code></pre>

    2. COI don't see anything obviously wrong - I'll have to try with the latest jQuery. I don't think this is a scope issue. At least in 1.8.* the this reference is setup to reference to the element where the event is being delivered (the form).

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).
