【问题描述】:
在我的 Ajax 函数中,我尝试将一个 int 参数传递给 Web 方法,但没有成功。 我在这里粘贴我的代码
Ajax 函数
$('#drpChurchNames').on('change', function () {
//alert($(this).val());
LoadFathersToChurch(churchId)
});
function LoadFathersToChurch(churchId) {
var url = '<%=ResolveUrl("WebMethods.aspx/GetFatherNames") %>';
$.ajax({
url: url,
type: "GET",
dataType: "json",
data:'{ Id: " '+churchId +' "}',
contentType: "application/json; charset=utf-8",
success: function (Result) {
$.each(Result.d, function (key, value) {
$("#drprevfather").append($("<option></option>").val
(value.Id).html(value.FatherName));
});
},
error: function (e, x) {
alert(x.ResponseText);
}
});
}
这是我的网络方法
[WebMethod]
[ScriptMethod(UseHttpGet = true)]
public static List<FatherNames> GetFatherNames(int ChurchId)
{
List<FatherNames> FathersList = new List<FatherNames>();
try
{
SqlCommand comChurchNames = new SqlCommand("GetFathers", conDB);
comChurchNames.CommandType = CommandType.StoredProcedure;
comChurchNames.Parameters.Add("@Id", SqlDbType.Int);
comChurchNames.Parameters["@Id"].Value = ChurchId;
if (conDB.State == ConnectionState.Closed)
conDB.Open();
SqlDataReader rdr = comChurchNames.ExecuteReader();
DataTable dt = new DataTable();
dt.Load(rdr);
foreach (DataRow r in dt.Rows)
{
FathersList.Add(new FatherNames
{
Id = (int)r["Id"],
FatherName = r["FatherName"].ToString()
});
}
}
这是我的 SP
ALTER PROCEDURE [dbo].[GetFathers]
@SelectIndexName int
AS
BEGIN
Select * from dbo.RevFathers
Where ChurchId = @SelectIndexName
END
