    copied!<p>I have some htmls, where some tags does not have any children, and I want to identify them and count the number of those tags.</p> <p>I have tried the following and it doesn't seem to work:</p> <pre><code>var count = 0; $("th[class=gridlabel]").each(function(){ if($("th[class=gridlabel]").children().length&lt;1) { count++; } }); return count; alert(count); </code></pre> <p>not sure what's the issue here.</p> <hr> <p>I have added some additional scripts from the html source code, I want to ensure the "count" will only count the first two tags, for "answer 3" and "answer 4", as their tags do not have children:</p> <pre><code> &lt;tr&gt; &lt;th class="gridlabel"&gt;answer 3&lt;/th&gt; &lt;td headers="q12_header1" class="gridcell"&gt;&lt;input&gt;&lt;div&gt;&lt;span&gt;answer 3&lt;/span&gt;&lt;label&gt;1&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;td headers="q12_header2" class="gridcell"&gt;&lt;input&gt;&lt;div&gt;&lt;label&gt;&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;th class="gridlabel"&gt;answer 4&lt;/th&gt; &lt;td headers="q12_header1" class="gridcell"&gt;&lt;input&gt;&lt;div&gt;&lt;span&gt;answer 4&lt;/span&gt;&lt;label&gt;1&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;td headers="q12_header2" class="gridcell"&gt;&lt;input&gt;&lt;div&gt;&lt;label&gt;&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;th class="gridlabel"&gt;other specify 1&lt;input&gt;&lt;label&gt;other specify 1&lt;/label&gt;&lt;/th&gt; &lt;td&gt;&lt;input&gt;&lt;div&gt;&lt;span&gt;other specify 1&lt;/span&gt;&lt;label&gt;1&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;td&gt;&lt;input&gt;&lt;div&gt;&lt;label&gt;2&lt;/label&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt; </code></pre>
