[jQuery] Re: Can you improve my Bring-to-Front code?

You could also say

  zmax = Math.max(zmax, this.style.zIndex);

I *think* should also work to replace that whole block of code, if you
prefer a functional approach:

$( this ).css( 'zIndex',
   Math.max.apply(null, $.map($( this ).siblings( '.draggable' ),
      function(){ return this.style.zIndex })
  );
