调用Web服务asmx无法正常工作

Question

我正在创建web服务asmx，通过Invoke按钮调用后工作正常。

 Parameter:  id = 1  procedureName = sasatestUpdate

现在我通过Ajax调用服务但没有任何反应。

示例：

function callService() {
            $.ajax({
                type: "POST",
                url: "appws.asmx?myServiceUpdate",
                data: "{ idTest: '1', procedureName: 'sasatestUpdate' }",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (data) { alert("success") },
                failure: function (errMsg) { alert("failure"); }
            });
        }

我没有得到任何警报（成功或失败）......

网络服务

string constring = "Data Source=myDb";
        SqlConnection conn;
        SqlCommand comm;

        [WebMethod]
        public string myServiceUpdate(string id, string procedureName)
        {
            conn = new SqlConnection(constring);
            conn.Open();

            comm = new SqlCommand();
            comm.Connection = conn;
            comm.CommandType = System.Data.CommandType.StoredProcedure;
            comm.CommandText = procedureName;
            comm.Parameters.AddWithValue("@idTest", id);
            try
            {
                comm.ExecuteNonQuery();
                return "Record Saved";
            }
            catch (Exception)
            {
                return "Not Saved";
            }
            finally
            {
                conn.Close();
            }
        }

There is a mismatch in parameter name of your web method. Change 'idTest' to 'id'.

  

数据：“{id：'1'，procedureName：'sasatestUpdate'}”
