Как убрать ссылку на активный пункт меню?

<script type="text/javascript">
         (function($){
         $('.row-fluid ul.thumbnails li.span6:nth-child(2n + 3)').css('margin-left','0px');
         $('.row-fluid ul.thumbnails li.span4:nth-child(3n + 4)').css('margin-left','0px');
         $('.row-fluid ul.thumbnails li.span3:nth-child(4n + 5)').css('margin-left','0px'); 
         })(jQuery);
         
         $(document).ready(function()
         {
             if (navigator.appName == "Opera")
             {
                 $('#myModal').removeClass('fades');
             }
         });
         var url = window.location;
         // Will only work if string in href matches with location
         $('ul.nav a[href="'+ url +'"]').parent().addClass('active');
         
         // Will also work for relative and absolute hrefs
         $('ul.nav a').filter(function() {
         return this.href == url;
         }).parent().addClass('active');
      </script>
