    <p>Is it possible, with jquery, to do the following: </p> <p>Given a document marked up with h1 through h6, append a "back to top" link after every heading element only if there is text written after the heading and before the next.. </p> <p>So:</p> <pre><code>&lt;h1&gt;h1&lt;/h1&gt; &lt;p&gt;text&lt;/p&gt; &lt;h2&gt;h2&lt;/h2&gt; &lt;h3&gt;h3&lt;/h3&gt; text text &lt;h4&gt;h4&lt;/h4&gt; &lt;br&gt;&lt;br&gt; &lt;h5&gt;h5&lt;/h5&gt; &lt;br&gt;&lt;br&gt;text &lt;h6&gt;h6&lt;/h6&gt; &lt;div&gt;test&lt;/div&gt; </code></pre> <p>Would result in </p> <pre><code>&lt;h1&gt;h1&lt;/h1&gt; &lt;p&gt;text&lt;/p&gt; &lt;a..&gt;back to top&lt;/a&gt; &lt;h2&gt;h2&lt;/h2&gt; &lt;h3&gt;h3&lt;/h3&gt; text text &lt;a..&gt;back to top&lt;/a&gt; &lt;h4&gt;h4&lt;/h4&gt; &lt;br&gt;&lt;br&gt; &lt;h5&gt;h5&lt;/h5&gt; &lt;br&gt;&lt;br&gt;text &lt;a..&gt;back to top&lt;/a&gt; &lt;h6&gt;h6&lt;/h6&gt; &lt;div&gt;test&lt;/div&gt; &lt;a..&gt;back to top&lt;/a&gt; </code></pre> <p>So text can be in paragraphs, divs, spans, or not marked up at all... </p> <p>I'm not sure how to do this, and how to even select the last element before the next (or what if it's the last ?) to append the link to. </p> <p>Any help (doesn't have to be a complete solution) is welcome.</p> <p><strong>Edit: The biggest issue is this:</strong></p> <p>Unfortunately I'm working with a cms that doesn't output paragraphs, but instead outputs </p> <pre><code> &lt;h1&gt;..&lt;/h1&gt;&lt;br&gt;text&lt;br&gt;&lt;br&gt;&lt;h2&gt;h2&lt;/h2&gt; </code></pre> <p>and so on..</p> <p>So also: </p> <pre><code>&lt;h1&gt;test&lt;/h1&gt; &lt;br&gt; &lt;h2&gt;test&lt;/h2&gt; </code></pre> <p>using the second solution presented here, that adds a top link when it shouldn't.. I'm not sure how to prevent that. </p> <p><strong>Edit 2:</strong></p> <p>Tried changing to: </p> <pre><code>$('#content').find('h1, h2, h3, h4, h5, h6').each( function(i, item) { var nextItems = $(item).nextUntil('h1, h2, h3, h4, h5, h6'); if (nextItems.filter('p, div, span').size() &gt; 0 || nextItems.filter(function() { return this.nodeType == Node.TEXT_NODE; }).size() &gt; 0) { nextItems.last().after('&lt;p&gt;&lt;a href="#toc-top" class="toc-top"&gt;Back To Top&lt;/a&gt;&lt;/p&gt;'); } }); </code></pre> <p>but it's never finding text nodes.. Any reason why? contents is just the h2 followed by br and text...</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.
