c# - How to fill a DropDown using Jquery Ajax Call?

Question

I have a WebMethod which gets data that I want to fill DropDown with in a DataSet. Currently I am filling the dropdown using a hardcoded object. But I want to replace this hard coded object with data returned by webmethod.

 [System.Web.Services.WebMethod]
         public static string GetDropDownDataWM(string name)
         {
             //return "Hello " + name + Environment.NewLine + "The Current Time is: "
             //    + DateTime.Now.ToString();

             var msg = "arbaaz";

             string[] name1 = new string[1];
             string[] Value = new string[1];
             name1[0] = "@Empcode";
             Value[0] = HttpContext.Current.Session["LoginUser"].ToString().Trim();
             DataSet ds = new DataSet();
             dboperation dbo = new dboperation();
             ds = dbo.executeProcedure("GetDropDownsForVendor", name1, Value, 1);

             return ds.GetXml(); 

         }

CLIENT SIDE(UPDATE 1):

  <script type = "text/javascript">
    function GetDropDownData() {
        var myDropDownList = $('.myDropDownLisTId');

        $.ajax({
            type: "POST",
            url: "test.aspx/GetDropDownDataWM",
            data: '{name: "abc" }',
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (data) {
                $.each(jQuery.parseJSON(data.d), function () {
                    myDropDownList.append($("<option></option>").val(this['FieldDescription']).html(this['FieldCode']));
                });
            },
            failure: function (response) {
                alert(response.d);
            }
        });
    }
    function OnSuccess(response) {
        console.log(response.d);
        alert(response.d);
    }
</script>

function GetDropDownData() {
    $.ajax({
        type: "POST",
        url: "test.aspx/GetDropDownDataWM",
        data: '{name: "abc" }',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(data.d)
                {

                    $.each(data.d, function (){
                        $(".myDropDownLisTId").append($("<option     />").val(this.KeyName).text(this.ValueName));
                    });
                },
        failure: function () {
            alert("Failed!");
        }
    });
}
