我的实际应用案例：

$("#user").autocomplete({
            source: function(request, response) {
                $.ajax({
                    url: "<!--{$basePath}-->decision_mobile/login/user_search/code/" + request.term+"/",
                    dataType: "json",
                    success: function(data) {
                        response($.map(data, function(item) {
                            return {
                                label: item.name_login  + "【" +item.role+"】",
                                value: item.name_login,
                                id:item.id
                            }
                        }));
                    }
                });
            },
            minLength: 2,
            select: function(e, ui)
            {
                $("#user_id").val(ui.item.id);
                $("#user_pwd").attr("disabled",false);
                $("#user_pwd").focus();
            }
        });
