Javascript/JQuery - How to get number of specific child elements
<p>I wish to get the number of all TR elements that have a input element in them somewhere. How should I proceed ?</p>

<p>Html :</p>

<p><code>&lt;tbody&gt;
&lt;tr&gt;
  &lt;td&gt;Ignore this item 1&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
  &lt;td&gt;Ignore this item 2&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
  &lt;td&gt;&lt;input blablabla&gt;... Include this TR...&lt;/td&gt;
&lt;/tr&gt;
&lt;/tbody&gt;</code></p>

<p>Thanks!</p>
