我想创建数据表，但我没有成功。有人可以帮助我。与web服务jQuery DataTable和服务器端数据问题
这是我的存储过程：
CREATE PROCEDURE [dbo].[pr_SearchMember]
@FilterTerm nvarchar(250) = NULL --parameter to search all columns by
, @SortIndex INT = 1 -- a one based index to indicate which column to order by
, @SortDirection CHAR(4) = 'ASC' --the direction to sort in, either ASC or DESC
, @StartRowNum INT = 1 --the first row to return
, @EndRowNum INT = 10 --the last row to return
, @TotalRowsCount INT OUTPUT
, @FilteredRowsCount INT OUTPUT
AS
BEGIN
--Wrap filter term with % to search for values that contain @FilterTerm
SET @FilterTerm = '%' + @FilterTerm + '%'
DECLARE @Person TABLE
(
CivilID NVARCHAR(12),
FirstName NVARCHAR(50)
, LastName NVARCHAR(50)
, Mobile NVARCHAR(20)
, ParentID NVARCHAR(12)
, RowNum INT
)
INSERT INTO @Person(CivilID
, FirstName
, LastName
, Mobile
, ParentID
, RowNum)
SELECT CivilID
, FirstName
, LastName
, Mobile
, ParentID
, Row_Number() OVER (
ORDER BY
/*VARCHAR, NVARCHAR, CHAR ORDER BY*/
CASE @SortDirection
WHEN 'ASC' THEN
CASE @SortIndex
WHEN 1 THEN CivilID
WHEN 2 THEN FirstName
WHEN 3 THEN LastName
WHEN 4 THEN Mobile
WHEN 5 THEN ParentID
END
END ASC,
CASE @SortDirection
WHEN 'DESC' THEN
CASE @SortIndex
WHEN 1 THEN CivilID
WHEN 2 THEN FirstName
WHEN 3 THEN LastName
WHEN 4 THEN Mobile
WHEN 5 THEN ParentID
END
END DESC
) AS RowNum
FROM dbo.Hierarchy
WHERE @FilterTerm IS NULL
OR CivilID LIKE @FilterTerm
OR FirstName LIKE @FilterTerm
OR LastName LIKE @FilterTerm
OR Mobile LIKE @FilterTerm
OR ParentID LIKE @FilterTerm
SELECT CivilID
, FirstName
, LastName
, Mobile
, ParentID
, RowNum
FROM @Person
WHERE RowNum BETWEEN @StartRowNum AND @EndRowNum
SELECT @TotalRowsCount = COUNT(*)
FROM dbo.Hierarchy
SELECT @FilteredRowsCount = COUNT(*)
FROM @Person
END
这是我的web服务
[WebMethod]

dr.Close();
TotalRowsCount = Convert.ToInt32(cmd.Parameters["@TotalRowsCount"].Value.ToString());

}
}
JavaScriptSerializer serializer = new JavaScriptSerializer();
data += "{\"sEcho\":\"" + sEcho + "\",";

}
catch (Exception ex)
{
throw ex.InnerException ;
}
if (cn.State == System.Data.ConnectionState.Open) cn.Close();
return data;
}
}
}
这是我的javascript代码
<script type="text/javascript">
$(document).ready(function() {
$("#org").jOrgChart({
chartElement: '#chart',
dragAndDrop: false
});
$('#members').dataTable({
"bServerSide": true,
"sAjaxSource": "CivilID.aspx/getData",
"sAjaxDataProp": "",
"bProcessing": true,
"bDestroy": true,
"fnServerData": function (sSource, aoData, fnCallback) {
$.ajax({
"dataType": 'json',
"contentType": "application/json; charset=utf-8",
"type": "GET",
"url": sSource,
"data": aoData,
"success": function (msg) {
var json = jQuery.parseJSON(msg.d);
fnCallback(json);
//$("#members").show();
}
});
},
"aoColumns": [
{ "sName": "civilID" },
{ "sName": "firstName" },
{ "sName": "lastName" },
{ "sName": "mobile" },
{ "sName": "parentID" },
{ "sName": "rowNum" }
]
});
});
</script>
我不知道，但我得到总是TypeError。请注意，我没有任何错误的JSON
下面是我的JSON数据
