jQuery: Getting "secondary" class
<p>I'm using jQuery to loop through some elements in a document. These elements are of type <code>&lt;tr&gt;</code> with class <code>.input-row</code>. Some of the elements can also have a secondary class (for example <code>.input-area</code>).</p>

<p>I use <code>$(".input-row").each()</code> to loop through the elements, but how can I determine if the <code>$(this)</code>-element has a "secondary" class and if so, get the name of this?</p>
