content filter hides everything when it is told to filter nothing
<p>I have this content filter that filters <code>&lt;div&gt;</code>s with the class of container (div.container) by hiding those div that do not contain what is typed inside the input field.</p>

<p>That way it only shows the <code>&lt;div&gt;</code>s that contain whatever is typed inside the input field.</p>

<p>Now, it checks and filters on each key up inside the input field so the results seem instant.</p>

<p>Now, my problem is that as a user deletes what is inside the input field, everything is hidden. Whereas when nothing is in the input field, everything should be visible.</p>

<p>It works fine in the separated case <a href="http://jsfiddle.net/aegq4/15/" rel="nofollow">in this js fiddle</a></p>

<p>but not when I applied it to my site as a whole. The filtering works, but everything disappears if nothing is typed in the input.</p>

<p>How can I get it to work so that when nothing is in the input, any div.container that was hidden before becomes visible? So that it works like it should, like a filtre when there is nothing to filtre everything is shown.</p>
