jQuery how to use .find
<pre><code>&lt;table id="myTable"&gt;
    &lt;tr id="myRow1"&gt;
        &lt;td&gt;hi&lt;/td&gt;
        &lt;td&gt;hello&lt;/td&gt;
        &lt;td&gt;comeon&lt;/td&gt;
    &lt;/tr&gt;
&lt;/table&gt;
</code></pre>

<ol>
<li><p>In the above scenario, what's the difference between</p>

<p><code>$("#myTable").find('tr')</code></p>

<p>and</p>

<p><code>$("#myTable").find('tr')[0]</code> or <code>$("#myTable").find('tr').get(0)</code>?</p></li>
<li><p>Also given <code>$("#myTable").find('tr')[0]</code>, how do I get the number of <code>td</code>s under it?</p></li>
</ol>

<p>Thanks.</p>
