    $(document).ready
(
function () {
    $("#btn").click
(
function () {
var _html;
  _html = '<tr>';
  _html += '<td>' + $("#tb").val() + '<input type="hidden" value="' + $("#tb").val() + '" name="tx_01_ID" /></td>';
    _html += '<td>' + $("#tb1").val() + ' <input type="hidden" value="' + $("#tb1").val() + '" name="tx_01_Name" /></td>';
    _html += '</tr>';
    $('#tbl').append(_html);
    return false
}
)
$("#btn1").click(function () {
    data = new Array();
    $("table[id*=tbl] tbody tr").each(function (index, item) {
        data[index] = new Object();
        data[index].id = $(item).find("input[type=hidden][name*=_ID]").val();
        data[index].name = $(item).find("input[type=hidden][name*=_Name]").val();
    });
    saveData(data);
});
}
)
function saveData(data) {
    var stringData = JSON.stringify(data);
    $.ajax({
        type: "POST",
        contentType: "application/json",
        data: "{d:" + stringData + "}",
        url: "WebService.asmx/x",
        dataType: "json",
        success: function (data) {
            $('#test').html(data.d);
        },
        error: function (XMLHttpRequest, textStatus, errorThrown) {

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[System.Web.Script.Services.ScriptService]
public class WebService : System.Web.Services.WebService
{
    DataClassesDataContext o = new DataClassesDataContext(ConfigurationManager.ConnectionStrings["DatabaseConnectionString"].ToString());
    [WebMethod]
    public string x(List<EMP1> d)
    {
     for(int i=1;i<d.Count();i++)
     {
         EMP q = new EMP();
          q.EID = Convert.ToInt32(d[i].ID.ToString());
          q.NAME = d[i].NAME.ToString();
            o.EMPs.InsertOnSubmit(q);
            o.SubmitChanges();
     }
        return "Record save sucessfully.";
