JavaScript - Yet another toggle (show/hide) combo box code

You probably already have found or used code to toggle 'select' elements (combo boxes). But some of them have prototype dependancies, some don't work for non-form based elements and some don't work with ajax based pages.

I just wrote this tiny code that seem to do the job on IE, both form and non-form based elements, both ajax and non-ajax based pages. Check it out:

/*
 * toggle select boxes by Kaisar
 */
function toggleSelectBoxes()
{
  var elems = document.getElementsByTagName("select");
  if (elems)
      for (i=0; i<elems.length; i++)
          elems[i].style.display = elems[i].style.display == 'none' ? '' : 'none';
}
