how to select unselected (not :selected) items in jquery?
<p>I'm looking for that selector that is the inverse of <code>:selected</code>.</p>

<p>It has to select every checkbox that are not selected.</p>

<p>I have tired this way, but it does not worked:</p>

<pre><code>$("#cont").find("input[type=checkbox]:not(:selected)")
</code></pre>
