title: How to remove one class value from a two part class setup
body: <p>I have the following piece of code:</p>
  
  <pre><code>if((String(parent).length &gt; 0) &amp;&amp; (String(this.className).length &gt; 0)) {
  </code></pre>
  
  <p>where this.className contains the value "top currentMenu"</p>
  
  <p>Using this.className name, I need a means of removing from this.className, "currentMenu" ONLY using jQuery, so that the end result for this.className is just "top".</p>
