从表格中的输入文本框中获取值并发送到json stringify

Question

此表格抓取用户ID的输入以获取分配的车辆列表，然后用户将需要输入表格中显示的每辆车的里程数，并且列表将与输入的里程数一起保存，问题是我我有无法获取我需要发送到数据库的里程数，当我将其发送到代码隐藏时，stringify会出现。我很欣赏任何建议或指向正确的方向。

- 使用Javascript -

<script type="text/javascript" src="Scripts/jquery.tabletojson.min.js"></script>



<script type="text/javascript">
 //Get the User ID input

    $(document).ready(function () {
        $('#btnSearch').click(function () {
            // alert("something");

            userInfo();
        });

        function userInfo() {
            var elem_id = $("#txtIBMEntry").val();
            var page_url = "MileageEntry.aspx/GetServices";
            $.ajax({
                type: "POST",
                url: page_url,
                data: "{'IBM':'" + elem_id + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (userDetails)
                { $("#infoDisplay").html(userDetails.d); }

            });

            //return false;
        };


        $('#btnSave').click(function () {

            // alert("This is going to activate the save procedure");

            setVehicleMileage();

        });

        function setVehicleMileage() {

            var page_urlSave = "MileageEntry.aspx/SetVehicleMileage";
            //var tbl = $('#results tr');
            var tbl = $('#results').tableToJSON();
            var table = JSON.stringify(tbl);


            $.ajax({
                type: "POST",
                url: page_urlSave,
                data: "{'tbl':'" + table + "'}",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (userDetails1)
                { $("#infoDisplay").html(userDetails1.d); }

            });
            //alert(JSON.stringify(table));


        };

    });



</script>

这是我加载html表的方法，我使用相同的代码来显示输入里程的文本框

   Public Shared Function GetString(ByVal IBM As String)
    'vb code 
   Dim ds As New DataSet

    IBM = Right("00000" & IBM, 5)

    ds = DBMgr.GetAssignedVeh(IBM)

    Dim table As DataTable = New DataTable()
    table = ds.Tables(0)

    Dim drows As DataRowCollection = table.Rows
    Dim HTML As StringBuilder = New StringBuilder
    ' HTML.AppendLine("<table>")

    If drows.Count > 0 Then

        HTML.Append("<table id='results' style='border-width:1; border-color:Silver; border-style:solid; padding:4;'>")
        HTML.Append("<thead>")
        HTML.Append("<tr><th>Name/IBM</th><th>Vehicle </th><th>Vehicle Number</th><th>Mileage</th>")
        HTML.Append("</tr>")
        HTML.Append("</thead>")


        For Each dr As DataRow In drows
            HTML.Append("<tbody>")
            HTML.AppendLine("<tr>")
            HTML.AppendFormat("<td>{0}&nbsp&nbsp</td>" & vbLf, dr("AssignedIBM"))
            HTML.AppendFormat("<td>{0}&nbsp&nbsp</td>" & vbLf, dr("VehicleName"))
            HTML.AppendFormat("<td>{0}&nbsp</td>" & vbLf, dr("VehNum"))
            HTML.AppendFormat("<td>{0}&nbsp<input id='txtMileageEntry'/></td>" & vbLf, "")
            HTML.AppendLine("</tr>")


        Next
        HTML.AppendLine("<tr>")
        HTML.AppendLine("<td colspan=3> </td>")
        HTML.AppendLine("<td></td>")
        HTML.AppendLine("</tr>")
    HTML.Append("</tbody>")
        HTML.AppendLine("</table>")
        'HTML.AppendLine("</div>")
        '<input type='button' id='btnSave1' value='Save Mileage' />

    Else : HTML.AppendLine("<label id='lblMessage'style='color:Red ;' >IBM Entered does not match any records, Please try again.</label>")

    End If

    Return HTML.ToString


End Function
