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

Answer 1

[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 DataSetToJSON(ds); 

     }

public static string DataSetToJSON(DataSet ds)
{

    Dictionary dict = new Dictionary();
    foreach (DataTable dt in ds.Tables)
    {
        object[] arr = new object[dt.Rows.Count + 1];

        for (int i = 0; i <= dt.Rows.Count - 1; i++)
        {
            arr[i] = dt.Rows[i].ItemArray;
        }

        dict.Add(dt.TableName, arr);
    }

    var lstJson = Newtonsoft.Json.JsonConvert.SerializeObject(dict);
    return lstJson;
}

Ajax Call

function GetAssociation() {

        var myDropDownList = $("#myDropDownLisTId");
        var post_data = JSON.stringify({ "name": "xyz"});
        $.ajax({
            type: "POST",
            url: "test.aspx/GetDropDownDataWM",
            data: post_data,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (response) {
                json_data = JSON.parse(response.d);
                myDropDownList.empty();
                for(i=0; i").val(json_data.Table[i][0]).html(json_data.Table[i][1]));
                }

            },
            failure: function (response) {
                alert(response.d);
            }
        });
    }
