ScrollTop - jQuery does not scroll -


i've got code:

http://jsfiddle.net/goodghost/mer3a/

$(function() {   var mywidth = $(".container").width();  var myheight = $(window).height();  console.log(myheight);  var myshift = (1920 - mywidth)/2;   $(".container").scrollleft(myshift);    //small window  $(".dragme").css({"left":myshift/10+"px", "width":(mywidth)/10+"px", "height":myheight/10+"px"});  $(".dragme").draggable({             addclasses: false,              containment: "parent",             drag: function(event, ui) {                var offset = $(this).offset();               var xpos = offset.left;               var ypos = offset.top;               console.log(ypos);               $(".container").scrollleft(xpos*10);               $(".container").scrolltop(ypos*10+"px");             }  }); });

what want achieve scroll in every direction image inside .container triggered movement of semi transparent div class dragme. know why it's working left , right, not top, bottom?

you not able use $('.container').scrolltop if allow div grow 100% in height. need set width , height .container , work charm.
