Problem with getting parent options

jQuery('body').on('click','#yt22',function(){jQuery.ajax({'type':'post','url':$(this).attr("href"),'success':function(data) {
                                var itemid = $(this).attr("id"); //this doesn't return id. Why?
                                $.fn.yiiGridView.update("duties-grid");
                                $.fn.yiiGridView.update("project-grid");

                                //var url = $(this).attr("href"); //This doesn't return the url used in the parent function.
                                console.log(itemid);
                                //var arr = url.split("/");
                                //var id = arr[arr.lenght-1];

                                /*console.log(id);
                                $.post("/YiiMain/app/ktcapskaita/index.php/form/UpdatedList", { "project_id": id }, function(data){
                                        var data = JSON.parse(data);
                                        $("#Duties_project_id").html(data.dropdown);
                                });*/
                                },'cache':false,'data':jQuery(this).parents("form").serialize()});return false;});
