    <p>I am trying to get the index of an element using jQuery to send to a PHP script.</p> <p><strong>Here is my XHTML</strong></p> <pre><code>&lt;form action="/accreditation/questions/" method="post" id="questions-form"&gt; &lt;fieldset id="question-0"&gt; &lt;legend&gt;Question&lt;/legend&gt; &lt;h3&gt;What colour is grass?&lt;/h3&gt; &lt;ul&gt; &lt;li&gt; &lt;input type="radio" name="answer[0]" value="0" id="radio-0-0" /&gt; &lt;label for="radio-0-0"&gt;Green&lt;/label&gt; &lt;/li&gt; &lt;li&gt; &lt;input type="radio" name="answer[0]" value="1" id="radio-0-1" /&gt; &lt;label for="radio-0-1"&gt;Red&lt;/label&gt; &lt;/li&gt; &lt;li&gt; &lt;input type="radio" name="answer[0]" value="2" id="radio-0-2" /&gt; &lt;label for="radio-0-2"&gt;Orange&lt;/label&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/fieldset&gt; &lt;fieldset id="question-1"&gt; &lt;legend&gt;Question&lt;/legend&gt; &lt;h3&gt;how old is alex&lt;/h3&gt; &lt;ul&gt; &lt;li&gt; &lt;input type="radio" name="answer[1]" value="0" id="radio-1-0" /&gt; &lt;label for="radio-1-0"&gt;21&lt;/label&gt; &lt;/li&gt; &lt;li&gt; &lt;input type="radio" name="answer[1]" value="1" id="radio-1-1" /&gt; &lt;label for="radio-1-1"&gt;11&lt;/label&gt; &lt;/li&gt; &lt;li&gt; &lt;input type="radio" name="answer[1]" value="2" id="radio-1-2" /&gt; &lt;label for="radio-1-2"&gt;23&lt;/label&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/fieldset&gt; &lt;/form&gt; </code></pre> <p>I need to get the index of the fieldset elements. I am currently using this each iterator (which I'd like not to change because it has a lot of other functions inside it).</p> <pre class="lang-js prettyprint-override"><code>$('#questions-form ul li').each(function() { qIndex = $('fieldset').index($('fieldset', $(this).parent())) }); </code></pre> <p>I'd like qIndex to be the index of fieldset relative to the form. For example, in this case I should have it equal to 0 and 1 (although there would be 6 values because it's looping through the list elements).</p> <p>I have played around for a while and have been unable to get the correct index. I keep getting not found (-1).</p> <p>If it helps, here is the code I'm using to get the list item's index relative to it's containing ul element.</p> <pre class="lang-js prettyprint-override"><code>index = $('li', $(this).parent()).index(this); </code></pre> <h3>What is wrong with my fieldset index grabbing code?</h3>

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).
