Проблема с отправкой данных строкового типа в веб-форме asp.net и Ajax

0 голосов
/ 16 декабря 2018

Я написал код, с помощью которого я могу легко работать на страницах, отличных от страницы поиска.Все параметры для базы данных, C # и Ajax определены в виде чисел.

На странице поиска, помимо числовых параметров, мне нужен параметр типа строки для перевода поискового запроса.

Когда я передаю фразу «2», программа работает правильно.

Но когда я передаю в программу строку типа «a», при прокрутке страницы программа выдаст ошибку.

Я пробовал много способов, но я не получил никаких результатов.

Спасибо.

My Global: 

public static void RegisterRoutes(RouteCollection routes)
{
            routes.Ignore("{resource}.axd/{*pathInfo}");

            routes.MapPageRoute("search", "search/{citName}/{searchitem}", "~/search/default.aspx");
            routes.MapPageRoute("edit", "edit-{alphabetID}", "~/manage/edit.aspx");
            routes.MapPageRoute("manage", "manage-{alphabetID}", "~/manage/default.aspx");
            routes.MapPageRoute("daste", "browse/{citName}/{mainName}/{secName}/{dasteName}", "~/daste.aspx");
            routes.MapPageRoute("sec", "browse/{citName}/{mainName}/{secName}", "~/sec.aspx");
            routes.MapPageRoute("base", "browse/{citName}", "~/default1.aspx");
            routes.MapPageRoute("main", "browse/{citName}/{mainName}", "~/main.aspx");
            routes.MapPageRoute("end", "ads/{alphabetID}/{adsName}", "~/end.aspx");
}

Моя search.aspx разметка страницы:

Я решил.

замените код ниже 

function GetRecords1() {
            pageIndex++;
            if (pageIndex == 2 || pageIndex <= pageCount) {
                $("#loader").show();
                $.ajax({
                    type: "POST",
                    url: "http://localhost:4295/search/default.aspx/GetCustomers1",
                    data: '{pageIndex: ' + pageIndex + ',item:' + JSON.stringify(<%= Variable_codebehind1 %>) + '}',
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: OnSuccess,
                    failure: function (response) {
                        alert(response.d);
                    },
                    error: function (response) {
                        alert(response.d);
                    }
                });
            }
        }

на: 

function GetRecords1() {
            pageIndex++;
            if (pageIndex == 2 || pageIndex <= pageCount) {
                $("#loader").show();
                var ada = { 'pageIndex': pageIndex, 'item': $("[id$=txtSearcher]").val() }
                $.ajax({
                    type: "POST",
                    url: "http://localhost:4295/search/default.aspx/GetCustomers1",
                    data: JSON.stringify(ada),
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: OnSuccess,
                    failure: function (response) {
                        alert(response.d);
                    },
                    error: function (response) {
                        alert(response.d);
                    }
                });
            }
        }
