Add hash(anchor) to url without scrolling

addHashToUrl.js

/**
 * Add hash to url without scrolling
 * 
 * @param String $url - it could be hash or url with hash
 * 
 * @return void
 */
function addHashToUrl($url)
{
  if ('' == $url || undefined == $url) {
    $url = '_'; // it is empty hash because if put empty string here then browser will scroll to top of page
  }
  $hash = $url.replace(/^.*#/, '');
  var $fx, $node = jQuery('#' + $hash);
  if ($node.length) {
    $fx = jQuery('<div></div>')
            .css({
                position:'absolute',
                visibility:'hidden',
                top: jQuery(window).scrollTop() + 'px'
            })
            .attr('id', $hash)
            .appendTo(document.body);
    $node.attr('id', '');
  }
  document.location.hash = $hash;
  if ($node.length) {
    $fx.remove();
    $node.attr('id', $hash);
  }
}

It doesn't work in IE6
