Optimize jQuery code
<p>What would be a better to state the following:</p>

<pre><code> var active = '-active';
 if ($j('body').hasClass('faqs')) { $j('.faqs-support').toggleClass('faqs-support' + active); }
 if ($j('body').hasClass('cameras')) { $j('.camera-support').toggleClass('camera-support' + active); }
 if ($j('body').hasClass('manuals')) { $j('.manuals-support').toggleClass('manuals-support' + active); }
 if ($j('body').hasClass('downloads')) { $j('.downloads-support').toggleClass('downloads-support' + active); }
</code></pre>
