Is there any other parameter like `this` in div name.first in javascript
<p>I see some thing like </p>

<p><code>$(#content).children(".p:first");</code></p>

<p>call the first <code>&lt;p&gt;</code> tag, except <code>first</code>, Is there any other parameter? thanks.</p>

<p>exaple:</p>

<pre><code>&lt;div id="content"&gt;
&lt;p&gt;aaa&lt;/p&gt;
&lt;p&gt;bbb&lt;/p&gt;
&lt;p&gt;ccc&lt;/p&gt;
</code></pre>

<p>
use <code>$(#content).children(".p:first");</code> echo </p>

<pre><code>&lt;div id="content"&gt;
&lt;p&gt;aaa&lt;/p&gt;
&lt;/div&gt;
</code></pre>

<p>Is there any <code>$(#content).children(".p:second");</code> or <code>$(#content).children(".p:last");</code> can be set?</p>
