JQuery append() CSS样式丢失

今天遇到了一些奇怪的问题，append后，CSS样式丢失，各种无法解决。

        $(document).ready(function(){

            $.ajax({
            url:"Json_menuAction_findAll.action",
            type:"post",
            dataType:"json",
            success:function(data){
            alert(data.menuL.length);



            xxx="<div>"+
            "<h3><a href=\"#\" title=\"First slide\" class=\"tooltip\" >第一</a></h3>"+
            "<div>xxxxx</div>"+
            " </div> ";

            $(xxx).appendTo("#accordion");
            $("#accordion").trigger("create"); 

            }
        });

        });
        </script>   

你这个是jqueryui，不是jquerymobile，出发父容器create事件无效，调用下accordion方法初始化就行

  $(xxx).appendTo("#accordion");
$("#accordion").accordion();
