    最后2个少了break，所以继续往后执行default了，break加上 

                  case "#lackbookpage":
                        pathn = "app_user_lackbookpage.jsp";
                        i = 4;
                        break;
                    case "#bookpagecheck":
                        pathn = "app_user_bookpagecheck.jsp";
                        i = 5;
                        break;
