如何使用 Ajax 发送到控制器？

Question

我正在尝试使用 Ajax 查询将查询发送到控制器，但我做不到。我知道的不多，我是实习生。在做之前，我看了一下如何用ajax查询发送数据，但是没有用。如果您能帮助我，我将不胜感激。

我的 .aspx 代码：

<script type="text/javascript">

        function customActionOn(itemStockCode) {
            $.ajax({
                url: '/SAPManagement/SAPUpdate.aspx/CustomActionOn',
                dataType: 'json',
                type: 'POST',
                data: "{'itemStockCode': '"+itemStockCode+"'}",
                contentType: 'application/json; charset=utf-8'
            });
        }

        function customActionOff(itemStockCode) {
            $.ajax({
                url: '/SAPManagement/SAPUpdate.aspx/CustomActionOff',
                dataType: 'json',
                type: 'POST',
                data: "{'itemStockCode': '" + itemStockCode + "'}",
                contentType: 'application/json; charset=utf-8'
            });
        }
    </script>


<telerik:GridTemplateColumn UniqueName="GetDeatils" ShowFilterIcon="false" AllowFiltering="false" HeaderText="Open and Close The Product On The Web" FilterControlWidth="10px" AutoPostBackOnFilter="false">
                            <ItemTemplate>
                                <%--<asp:Button CommandName="GetDeatils" ID="GetDeatils2" OnClientClick='<%# "javascript:openwin("+Eval("ItemStockCode").ToString()+")" %>'
                                    runat="server" Text="Detay"></asp:Button>--%>
                                <asp:Button ID="Button3" runat="server" CssClass="btn btn-block green" Text="Open" OnClientClick='<%# "customActionOn("+Eval("ItemStockCode").ToString()+")" %>'></asp:Button>
                                <asp:Button ID="Button1" runat="server" CssClass="btn btn-block red" Text="Close" OnClientClick='<%# "customActionOff("+Eval("ItemStockCode").ToString()+")" %>'></asp:Button>
                            </ItemTemplate>
                        </telerik:GridTemplateColumn>

.aspx.cs 代码：

[System.Web.Services.WebMethod]
    public void CustomActionOn(string itemStockCode)
    {
        products = new LogicRules.B2B.BL_Product().GetAllProductsForSAPUpdate().OrderBy(x => x.ItemName).ToList();
        var selectedProduct = products.Where(x => x.ItemStockCode == itemStockCode).FirstOrDefault();
        selectedProduct.PublishOnB2B = true;
        new Core.Log.ArkLogs().WriteProductUpdateLog(JsonConvert.SerializeObject(selectedProduct), User.Identity.GetUserId<int>(), "Product", "ISBN", selectedProduct.ItemStockCode);
        var retValues = new SapFunction.ProductFunction().updateProduct(selectedProduct);
    }


    [System.Web.Services.WebMethod]
    public void CustomActionOff(string itemStockCode)
    {
        products = new LogicRules.B2B.BL_Product().GetAllProductsForSAPUpdate().OrderBy(x => x.ItemName).ToList();
        var selectedProduct = products.Where(x => x.ItemStockCode == itemStockCode).FirstOrDefault();
        selectedProduct.PublishOnB2B = false;
        new Core.Log.ArkLogs().WriteProductUpdateLog(JsonConvert.SerializeObject(selectedProduct), User.Identity.GetUserId<int>(), "Product", "ISBN", selectedProduct.ItemStockCode);
        var retValues = new SapFunction.ProductFunction().updateProduct(selectedProduct);
    }

我无法通过这种方式向控制器发送数据。我得到了正确的 itemstockcode 值。但数据不会进入控件。如果您能帮助我，我将不胜感激。

您可以更改输入模型，而不是获取字符串，而是获取对象

[System.Web.Services.WebMethod]
public void CustomActionOff(ItemStockCodeModel itemStockCodeRequest)
{
    products = new LogicRules.B2B.BL_Product().GetAllProductsForSAPUpdate().OrderBy(x => x.ItemName).ToList();
    var selectedProduct = products.Where(x => x.ItemStockCode == itemStockCodeRequest.itemStockCode).FirstOrDefault();
    selectedProduct.PublishOnB2B = false;
    new Core.Log.ArkLogs().WriteProductUpdateLog(JsonConvert.SerializeObject(selectedProduct), User.Identity.GetUserId<int>(), "Product", "ISBN", selectedProduct.ItemStockCode);
    var retValues = new SapFunction.ProductFunction().updateProduct(selectedProduct);
}

并在命名空间中定义模型

public class ItemStockCodeModel
{
      public string ItemStockCode{set;get;}
}
