Ajax成功功能无法接收数据 [英] Ajax success function not receive data

问题描述

下面是我的Web表单的Web方法，该方法将返回数据列表，并且可以正常工作:

Below is webmethod of my web form which is returning a List of data and it works fine:

[WebMethod]
public static List<SalesInvoiceFinalCalculationEntity> salesInvoiceFinalCalculaiton(string InvoiceNo)
{
    List<SalesInvoiceFinalCalculationEntity> list = new List<SalesInvoiceFinalCalculationEntity>();
    list = SalesInvoiceManager1.salesInvoiceFinalCalculaiton(InvoiceNo);
    return list;
}

但是在下面的Ajax函数中，我无法检索数据.当我将数据绑定到Ajax成功函数中的文本框时，它会在HTML文本框中显示未定义的文本.

But in below Ajax function, I can't retrieve the data. When I bind data to textbox in ajax success function, it displays Undefined text in Html textBox.

function salesInvoiceFinalCalculaiton() {        

    var InvoiceNo = $("#txt_InvoiceNo").val();
    $.ajax({
        async: false,
        type: "POST",
        contentType: "application/json; charset=utf-8",
        url: "/AjaxRequestToServer.aspx/salesInvoiceFinalCalculaiton", //URI   
        data: "{InvoiceNo:'" + InvoiceNo + "'}",
        dataType: "json",
        success: function (data) {

            document.getElementById("txtinvoicevalue").value=(data.totalprice);
            document.getElementById("txtTotalDiscount").value = data.discountamt;
            document.getElementById("txtTotalTaxableValue").value = data.taxableamt;
            document.getElementById("txtTotalCGST").value = data.cgstamt;
            document.getElementById("txtTotalSGST").value = data.sgstamt;
            document.getElementById("txtGrandTotal").value = data.grandtotal;

        },
        error: function (xhr) {
            if (xhr.statusText == "Invalid Request") {
                sessionStorage.clear();
            }
        }
    });
}

这是数据层和存储过程:

Here is Data Layer and the stored procedure:

 public static List<SalesInvoiceFinalCalculationEntity> salesInvoiceFinalCalculaiton(string InvoiceNo)
        {
            try
            {


                List<SalesInvoiceFinalCalculationEntity> SalesInvoiceFinalCalculation = new List<SalesInvoiceFinalCalculationEntity>();

                DataSet ds = SqlHelper.ExecuteDataset(Util.ConnectionString, CommandType.StoredProcedure, "sp_salesInvoiceFinalCalculaiton",
                    new SqlParameter("@InvoiceNo", InvoiceNo));

                foreach (DataRow dr in ds.Tables[0].Rows)
                {
                    SalesInvoiceFinalCalculationEntity list = new SalesInvoiceFinalCalculationEntity(dr);
                    SalesInvoiceFinalCalculation.Add(list);
                }
                return SalesInvoiceFinalCalculation;
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

这是我的实体类:

public class SalesInvoiceFinalCalculationEntity
    {
        public int InvoiceNo { get; set; }
        float totalprice { get; set; }
        float discountamt { get; set; }
        float taxableamt { get; set; }
        float cgstamt { get; set; }
        float sgstamt { get; set; }
        float grandtotal { get; set; }
        public SalesInvoiceFinalCalculationEntity() { }
        public SalesInvoiceFinalCalculationEntity(DataRow dr)
        {
            InvoiceNo = Convert.ToInt32(dr["InvoiceNo"]);
            totalprice = float.Parse(dr["totalprice"].ToString());
            discountamt = float.Parse(dr["discountamt"].ToString());
            taxableamt = float.Parse(dr["taxableamt"].ToString());
            cgstamt = float.Parse(dr["cgstamt"].ToString());
            sgstamt = float.Parse(dr["sgstamt"].ToString());
            grandtotal = float.Parse(dr["grandtotal"].ToString());
        }
    }

为什么没有在成功功能中接收数据！

why is data is not received in success function!

推荐答案

最终解决了它.我忘了提到

Finally resolved it. I forgot to mentioned

在

SalesInvoiceFinalCalculationEntity

确定所有变量和 document.getElementById("txtinvoicevalue").value =(data.d [0] .totalprice); 而不是

document.getElementById("txtinvoicevalue").value =(data.totalprice);
