Hello,

I'm trying to save the state of a slideToggle. Why is my var id giving a "undefined" error? Is there a simple way to do this action (save state of slideToggle)? (I'm a javascript / jQuery newbie).

1.  $("a#toggle").click(function(){
     var id = $(this).next().attr('id');
     $('#'+id).slideToggle('400',function(){
      if ($(this).is(':hidden')) {
       var state = "closed";
       $.cookie('#'.id, state);
       return false;
      } else if ($(this).is(':visible')) {
       var state = "open";
       $.cookie('#'.id, state);
       return false;
      } else {
       return false;
      }
     });
    });
   
    var show = $.cookie('#'.id);
    if(show == 'closed'){
     alert(show);
     $(id).removeClass().addClass('hidden');
    } else {
     alert(show);
     $(id).removeClass().addClass('container_toggle');
    }
