ユーザーがカートにアイテムを追加できる MVC アプリを作成しています。また、特定のアイテムの一部を支払うこともできるので、支払い額を指定するための TextBox があります。Ajax ActionLink を使用して更新/カートへの追加アクションを処理しているため、部分ビューを使用して画面を更新せずにカートの数を増やすことができます。私の問題は、TextBox に入力された値を PartialViewResult 関数に渡したりアクセスしたりする方法が見つからないことです。

これが私のモデルです...

Public Class StudentSchoolFee_Transaction

    Public Property SchoolFeeId As Integer
    Public Property Title As String
    Public Property Price As Decimal
    Public Property AmountDue As Decimal
    <DisplayFormat(ApplyFormatInEditMode:=True, DataFormatString:="{0:C2}")>
    Public Property Amount As Decimal
    Public Property Description As String
    Public Property AcceptPartialPayment As Boolean
    Public Property StudentId As Integer

    Public Property TransactionId As Integer

End Class

Public Class AssignedFeesModel

    Public Property StudentId As Integer
    Public Property StudentNumber As Long
    Public Property SiteId As String

    Public Property SelectedSchoolFeeId As Integer
    Public Property SelectedAcceptPartial As Boolean
    Public Property SelectedAmountDue As Decimal
    Public Property SelectedAmount As Decimal
    Public Property SelectedTransactionId As Integer

    Public Property AssignedFeesCol As System.Collections.Generic.List(Of   StudentSchoolFee_Transaction)

    Public Sub New()

    End Sub

    Public Sub New(ByVal _Deliver As EMS.Grid.Deliver, ByVal _StudentId As String)

        Dim SelectedStudent As New Library.Student(_Deliver, _StudentId)

        AssignedFeesCol = New System.Collections.Generic.List(Of StudentSchoolFee_Transaction)

        StudentId = SelectedStudent.Id
        StudentNumber = SelectedStudent.StudentNumber
        SiteId = SelectedStudent.SiteId

        'Load AssignedFeesCol   
    End Sub
End Class

これが私の最初の読み込み ActionResult と私の AddAssignedFee PartialViewResult で、カートの数を更新します...

    Function AssignedFees(ByVal StudentId As String, Optional ByVal ErrorMessage As String = "") As ActionResult
        Dim oDeliver As New EMS.Grid.Deliver
        oDeliver.UDLNameOrConnString = ConfigurationManager.ConnectionStrings("DefaultConnection").ConnectionString

        Dim m As New AssignedFeesModel(oDeliver, StudentId)

        Dim stu As New Library.MealHistoryDB.Student(oDeliver, m.StudentNumber, UserSession.GetSession.DistrictId)

        Return View(m)
    End Function

    Public Function AddAssignedFee(ByVal StudentId As Integer, ByVal SchoolFeeId As Integer, ByVal SelectedAmount As Decimal) As PartialViewResult

        Dim oDeliver As New EMS.Grid.Deliver
        oDeliver.UDLNameOrConnString = ConfigurationManager.ConnectionStrings("DefaultConnection").ConnectionString

        With New Library.Ecommerce.SchoolFee(oDeliver, SchoolFeeId)
            .AddToCart(oDeliver, UserSession.GetSession.ParentId, StudentId, SelectedAmount)
        End With

        Return PartialView("_CartButton") ', New Global.MSM.mobile.CartButton())

    End Function

そして、ここに私のAjaxアクションリンクがあります.1つ目は、金額が指定されていないアイテムを追加するためのもので、機能します。2 つ目は、部分的な支払い金額を持つことができるアイテムを更新するためのもので、金額を PartialViewResult に渡す方法が見つかりません。

@Ajax.ActionLink("Add", "AddAssignedFee", "Parent", New With {.StudentId = currentItem.StudentId, .SchoolFeeId = currentItem.SchoolFeeId, .SelectedAmount = currentItem.Amount}, New AjaxOptions() With {.HttpMethod = "POST", .InsertionMode = InsertionMode.Replace, .UpdateTargetId = "btnCartContainer"}, New With {.class = "button"})


@Ajax.ActionLink("Update", "AddAssignedFee", "Parent", New With {.StudentId = currentItem.StudentId, .SchoolFeeId = currentItem.SchoolFeeId, .SelectedAmount = currentItem.Amount}, New AjaxOptions() With {.HttpMethod = "POST", .InsertionMode = InsertionMode.Replace, .UpdateTargetId = "btnCartContainer"}, New With {.class = "button"})

Update リンクに対して ".SelectedAmount = Model.SelectedAmount" も試しましたが、入力した Amount を PartialViewResult に渡す方法が見つからないようです。

助言がありますか？

ありがとうございました！リンジー

あなたはajax呼び出しをやってみるかもしれません

$('.Link').on('click', function(){
    $.ajax({
        url: "@(Url.Action("AddAssignedFee", "Controller")",
        type: "POST",
        data: { textValue: $('.PaymentAmount').val(), data2: 'data2' }
        cache: false,
        async: true,
        success: function (result) {
            $(".Content").html(result);
        }
    });
});

うまくいけば、これが役に立ちます
