jquery remove all classes from class
<p>How can I remove all classes from a class but keep the original class?</p>

<p>html</p>

<pre><code>&lt;div class="document-wrapper removeme1 removeme2 removeme3"&gt;&lt;/div&gt;
</code></pre>

<p>jquery</p>

<pre><code>$('.document-wrapper').removeClass();
</code></pre>

<p>end with this</p>

<pre><code>&lt;div class="document-wrapper"&gt;&lt;/div&gt;
</code></pre>
