    <p>I have an html "details" element that serves as my page's table of contents. I'm trying to dynamically rewrite the document's html "title" tag based on the currently "active" element in the TOC (a class="active")</p> <p>However, although it works in the console, when I actually embed it into the footer of my page, I'm getting a console error:</p> <blockquote> <p>Uncaught ReferenceError: jQuery is not defined</p> </blockquote> <p>I'm including jQuery into the footer of my page just before this inline script. Other jquery elements on the page are working fine. What could be the problem with this script?</p> <pre><code>&lt;script&gt; jQuery(document).ready(function(){ var title = jQuery('.myEl').find('a.active').text(); jQuery('title').text(title); }); &lt;/script&gt; </code></pre> <p>The HTML for this page looks like this:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html lang="en-US"&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt; &lt;title&gt;Customer Testimonials (Page 3)&lt;/title&gt; &lt;link rel="stylesheet" href="styles.css" media="screen" /&gt; &lt;meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0" /&gt; &lt;!--[if lt IE 9]&gt;&lt;script src="//html5shiv.googlecode.com/svn/trunk/html5.js"&gt;&lt;/script&gt;&lt;![endif]--&gt; &lt;/head&gt; &lt;body&gt; &lt;details class="myEl" open="open"&gt;&lt;summary&gt;In this article&lt;/summary&gt; &lt;ol&gt; &lt;li&gt;&lt;a href="mypage/"&gt;Introduction&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="mypage/2/" class="active"&gt;Title for the second page&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="mypage/3/"&gt;Title for the third page&lt;/a&gt;&lt;/li&gt; &lt;/ol&gt; &lt;/details&gt; &lt;script type='text/javascript' src='scripts.jquery.js' async='async'&gt;&lt;/script&gt; &lt;script&gt; jQuery(document).ready(function(){ var title = jQuery('.myEl').find('a.active').text(); jQuery('title').text(title); }); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

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).
