I receive this as a response from an ajax call. My question is how can I get the values of the object?

{"countries":[{"country_id":730,"country":"El Salvador"},{"country_id":756,"country":"Guatemala"},{"country_id":767,"country":"Indonesia"}]}

my ajax call is this:

$.ajax({
    type: "POST",
    dataType:"json",
    url:getCountriesPackages,
    data: "transferUrl=countries?service_id="+serviceId,
    success: function(data) {

        $.each(data, function(k, v) {
          console.log(k);
        });
    }
});

thank you

You already have a JSON, you can traverse it using $.each():

var obj = {
  "countries": [{
    "country_id": 730,
    "country": "El Salvador"
  }, {
    "country_id": 756,
    "country": "Guatemala"
  }, {
    "country_id": 767,
    "country": "Indonesia"
  }]
};

$.each(obj, function(k, v) {
  $.each(v, function(kk, kv) {
    console.log("Country ID: " + kv.country_id);
    console.log("Country: " + kv.country);
  });
});
