jquery removing a class (if it exists and adding a new class)
<p>I'm trying use jquery to remove a class from an element (not knowing ahead of time if it exists) and add a new element to replace it.</p>

<p>Would this be the best way (I'm skepticle because its not checking to see if the class exists before removing it):</p>

<pre><code>$(elem).removeClass(oldClass).addClass(newClass);
</code></pre>

<p>thanks</p>
