HTML Question

Through ajax not able to fill HTML dropdown

<script type="text/javascript">
$(document).ready(function () {
url: '/Umbraco/api/RegisterUser/GetCountry',
type: 'GET', // You can use GET
data: '{}',
dataType: "json",
context: this,
success: function (data) {

$.each(data, function (key, item) {
.attr("value", item.Country_name)

error: function (request) {

My code return on URL path is

public string GetCountry()
String daresult = null;
DataSet ds = new DataSet();
DataTable dt = new DataTable();
DataTable dt1=new DataTable();
using (SqlDataAdapter da = new SqlDataAdapter("SELECT countryid,country_name FROM country_master", UmbracoConnectionString))

System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>(10);
Dictionary<string, object> row;

foreach (DataRow dr in dt1.Rows)
DataRow[] dr1 = dt1.Select("countryid=" + dr["countryid"]);
if (dr1.Count() > 0)
row = new Dictionary<string, object>();
foreach (DataColumn col in dt1.Columns)
if (col.ColumnName == "country_name")
row.Add(col.ColumnName, dr[col]);

return serializer.Serialize(rows);

My HTML code is below where i had inserted some of the data manually

Country:<select id="ddcountry">

But by doing all this things **how should I fill my dropdown with retriving data as data shown in below image

On alert of data i am getting data as below

enter image description here


I guess, It will solve your issue:

First, You need to convert your JSON String to JSON Array and Then Iterate it to dynamically create options for your select dropdown.

var res = jQuery.parseJSON(data);

$.each(res , function (key, item) {
          .attr("value", item.country_name)
