在Jquery中创建新的Div Draggable

$(document).ready(function() {

 $("#draggable").draggable({ 
   containment: 'parent',handle: 'drag_border',drag: function(e,ui) {
          var top = ui.position.top;
          var left = ui.position.left;
          $("#top").html(top);
          $("#left").html(left);
           }
       }); 
   });

       function New_Text() {   
            $("<div id=\"draggable\" style=\"width: 200px; height: 50px; border:dashed thin; BACkground-color: #fff\">Drag me</div>").appendTo("div#drag_border"); 
              }

谢谢
