我怎么能传递一个texbox进入到PartialViewResult值？ [英] How can I pass a value entered in a texbox to a PartialViewResult?

问题描述

我创建一个MVC应用程序，用户可以将项目添加到他们的购物车。他们还可以对某些项目的部分款项，所以我有一个TextBox为他们指定要付多少钱。我使用一个Ajax ActionLink的处理更新/添加到购物车的行为，这样我可以增加车数，而无需使用局部视图刷新屏幕。我的问题是，我无法找到一个方法来传递或访问该文本框进入到我的PartialViewResult函数的值。

I am creating an MVC app where the user can add items to their cart. They can also make partial payments on certain items so I have a TextBox for them to specify how much they want to pay. I am using an Ajax ActionLink to handle the Update/Add to cart actions so that I can increment the cart count without refreshing the screen using a partial view. My issue is that I can't find a way to pass in or access the value entered in the TextBox to my PartialViewResult function.

下面是我的模型......

Here is my Model...

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

下面是我的初始加载的ActionResult和我AddAssignedFee PartialViewResult刷新购物车算...

Here are my initial load ActionResult and my AddAssignedFee PartialViewResult to refresh the cart count...

    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

这是我的阿贾克斯行动环节，首先是添加没有指定金额的项目和它的作品。二是要更新的，可以有一个部分付款金额，我无法找到一个方法来量传递给PartialViewResult一个项目。

And here are my Ajax action links, the first is for Adding an item with no Amount specified and it works. The second is for Updating an item that can have an partial payment Amount and I can't find a way to pass the amount to the PartialViewResult.

@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"})

我也尝试.SelectedAmount = Model.SelectedAmount为更新链接，但我似乎无法找到一种方法来输入的金额传递给PartialViewResult。

I have also tried ".SelectedAmount = Model.SelectedAmount" for the Update link but I can't seem to find a way to pass the entered Amount to the PartialViewResult.

有什么建议？

感谢您！

Thank you! Lindsay

推荐答案

你可以尝试做一个Ajax调用

you might try doing an ajax call

$('.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);
        }
    });
});

希望这有助于
