    <p>I have adequate knowledge about jQuery and its usage but today i got into a trouble of getting the column index of matching label inside <code>th</code> element of <code>table</code> using jQuery. I want to get the index of <code>th</code> element having <code>label</code> text as <strong>Mobile</strong>. The index should be 2 in this case. I am getting the actual index but this is not the correct way of doing it. So i want to know why jQuery is not giving me the right index using <code>index()</code> method.</p> <p>I have also written the <a href="http://jsfiddle.net/furqansafdar/DHkb4/2/" rel="nofollow">JS Fiddler</a> for this.</p> <p><strong>jQuery</strong></p> <pre class="lang-js prettyprint-override"><code>var elem = $('#tbl th'); var rIndex; alert('Length : ' + elem.length); var index = elem.filter( function(index){ var labelText = $(this).find('label').text(); //alert(index + ' - ' + labelText); var result = labelText == 'Mobile'; if (result) rIndex = index; return result; }).index(); alert("jQuery Index : " + index); alert("Actual Index : " + rIndex); </code></pre> <p><strong>HTML</strong></p> <pre class="lang-html prettyprint-override"><code>&lt;table id="tbl"&gt; &lt;tr&gt; &lt;td&gt;&lt;/td&gt; &lt;th&gt;&lt;label&gt;Application No.&lt;/label&gt;&lt;/th&gt; &lt;td&gt;&lt;/td&gt; &lt;th&gt;&lt;label&gt;Name&lt;/label&gt;&lt;/th&gt; &lt;td&gt;&lt;/td&gt; &lt;th&gt;&lt;label&gt;Mobile&lt;/label&gt;&lt;/th&gt; &lt;td&gt;&lt;/td&gt; &lt;th&gt;&lt;label&gt;Gender&lt;/label&gt;&lt;/th&gt; &lt;/tr&gt; &lt;/table&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.
