javascript - Jquery ajax函数调用vb文件中的代码

Question

首先，我想做的是填充一个下拉框，如下所示:

<asp:DropDownList CssClass="ui dropdown" ID="drpGolfClub" runat="server"></asp:DropDownList>

一些值给了我高尔夫俱乐部 ID 和名称。问题是，使用 jQuery 我似乎无法运行后面的 vb 文件中的代码。一切看起来都是这样的。在 aspx 文件中:

 function loadGolfClub()
        {
                alert('inside method');
                //debugger;
                $.ajax({
                    type: "POST",
                    url: "Register.aspx/LoadGolfClub",
                    data: '{}',
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    async: false,
                    success: function (Result) {

                        debugger;
                        Result = Result.d;
                        $('#<%=drpGolfClub.ClientID%>').empty();
                        $('#<%=drpGolfClub.ClientID%>').prepend("<option value='0'>" +"Select" + "</option>");
                        $.each(Result, function (key, value) {
                            $('#<%=drpGolfClub.ClientID%>').append($("<option></option>").val(value.GolfClubId).html(value.GolfClubName));
                            $('#<%=drpGolfClub.ClientID%>')[0].selectedIndex = 1;
                        });
                        alert("in sucess!");
                    },

                    failure: function () {
                        alert("Failed!");
                    }
                });
            } 

aspx文件后面的vb是这样添加的:

Imports System
Imports System.Linq
Imports System.Web
Imports System.Web.UI
Imports Microsoft.AspNet.Identity
Imports Microsoft.AspNet.Identity.EntityFramework
Imports Microsoft.AspNet.Identity.Owin
Imports Owin
Imports System.Data
Imports System.Web.Services
Imports System.Reflection
Imports Golfbook.CoreLibrary
Imports Golfbook.CoreLibrary.Golfbook.Services


Public Class Register
    Inherits System.Web.UI.Page
    Shared objGCBO As New GolfClubBO()

    Shared objGolfClubService As New Golfbook.CoreLibrary.Golfbook.Services.GolfClub.GolfClubDetails

    Shared details As New List(Of GolfClubBO)()
    Shared _loginName As String
    Shared loginName As String

    Private Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load

    End Sub

    <WebMethod()>
        <System.Web.Script.Services.ScriptMethod(ResponseFormat:=System.Web.Script.Services.ResponseFormat.Json)>
        Public Shared Function LoadGolfClub() As GolfClubBO()
            Dim details As New List(Of GolfClubBO)()
            Try
                details = objGolfClubService.LoadGolfClub()
            Catch ex As Exception

            End Try
            Return details.ToList.ToArray()
        End Function
End Class

我知道vb中的page_load已运行，但它永远不会进入那里的函数。我现在已经尝试了“一切”，但不知道该怎么做。函数中添加的警报框正在触发，因此它开始运行

我知道 JQuery 正在工作，因为我已将一些值添加到随机文本框中:$('#txtFirstName').val('Martin');

有什么提示可以解释这可能是什么原因吗？

Answer 1

如上所述，感谢 ADyson，解决我的问题的答案是解决这个问题:在 ~/App_Start/RouteConfig.cs 内更改:

settings.AutoRedirectMode = RedirectMode.Permanent;
To:

settings.AutoRedirectMode = RedirectMode.Off;

谢谢大家的回复!
