How to check if an element exist into another element?
<p>I'd like, to jQuery, understand if an element exist into another element.</p>

<p>Somethings like :</p>

<pre><code>if($('#container').find('.search_element'))
</code></pre>

<p>must return YES if <code>.search_element</code> is into <code>#container</code>, NO otherwise.</p>

<p>How can I do it? Tried with $.contains('#container', '.search_element') but seems that this function doesnt works...</p>
