    <p>I'm looking for a way to gather all of the text in a jQuery wrapped set, but I need to create spaces between sibling nodes that have no text nodes between them.</p> <p>For example, consider this HTML:</p> <pre><code>&lt;div&gt; &lt;ul&gt; &lt;li&gt;List item #1.&lt;/li&gt;&lt;li&gt;List item #2.&lt;/li&gt;&lt;li&gt;List item #3.&lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p>If I simply use jQuery's <code>text()</code> method to gather the text content of the <code>&lt;div&gt;</code>, like such:</p> <pre><code>var $div = $('div'), text = $div.text().trim(); alert(text); </code></pre> <p>that produces the following text:</p> <blockquote> <p>List item #1.List item #2.List item #3.</p> </blockquote> <p>because there is no whitespace between each <code>&lt;li&gt;</code> element. What I'm actually looking for is this (note the single space between each sentence):</p> <blockquote> <p>List item #1. List item #3. List item #3.</p> </blockquote> <p>This suggest to me that I need to traverse the DOM nodes in the wrapped set, appending the text for each to a string, followed by a space. I tried the following code:</p> <pre><code>var $div = $('div'), text = ''; $div.find('*').each(function() { text += $(this).text().trim() + ' '; }); alert(text); </code></pre> <p>but this produced the following text:</p> <blockquote> <p>This is list item #1.This is list item #2.This is list item #3. This is list item #1. This is list item #2. This is list item #3. </p> </blockquote> <p>I assume this is because I'm iterating through every descendant of <code>&lt;div&gt;</code> and appending the text, so I'm getting the text nodes within both <code>&lt;ul&gt;</code> and each of its <code>&lt;li&gt;</code> children, leading to duplicated text.</p> <p>I think I could probably find/write a plain JavaScript function to recursively walk the DOM of the wrapped set, gathering and appending text nodes - but is there a simpler way to do this using jQuery? Cross-browser consistency is very important.</p> <p>Thanks for any help!</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.
