Как я могу получить код набора данных, когда я его предупреждаю.

$('.flag-container').on('click', function () {
    var values = $('.flag-container').val();
    //var country = $(this).val();  

    alert(values);
});

Answer 1

Вы пытаетесь получить атрибут элемента списка, просто вызовите его внутри вашего .on ():

  $('#iti-item-dz').attr('data-dial-code');

Answer 2

Просто используйте родительский класс, который в теге ul, и используйте контекст this, чтобы получить значение элемента, по которому щелкнули.и вы получите все данные списка элементов, нажав на элемент.

Запустите приведенный ниже фрагмент

$('.country-list .country').on('click', function() {
    var country = $(this).find('.country-name').text();
    alert(country);
  });

$(document).ready(function() {
  $('.country-list .country').on('click', function() {
    var country = $(this).find('.country-name').text();
    alert(country);
  });
})

.country {
  display: block;
  padding: 5px;
  background: gray;
  cursor: pointer;
}

Answer 3

Для доступа к data attributes вы можете использовать data method

$('#iti-item-dz').data('dial-code') // will return the number 213

Чтобы получить все телефонные коды всех ликов, используйте

let dialCodes = []

$('#country-listbox li').each(function() {
    dialCodes.push($(this).data('dial-code'))
})

Чтобы получить телефонный код выбранного элемента списка, используйте этот

let dialCode

$('#country-listbox li').on('click', function() {
    dialCode = $(this).data('dial-code')
})
