body: <p>Is there a jQuery equivalent to provide the same functionality as <a href="http://www.scriptiny.com/2008/05/sliding-javascript-menu-highlight-1kb/" rel="nofollow">here</a>? </p>
  
  <p>JavaScript</p>
  
  <pre><code>var menuSlider=function(){

          var i,l,w,p; i=0; l=e.length;
          for(i;i&lt;l;i++){
