import $ from 'jquery';

$(() => {
  $(document).on('click', '.js-copy-string', (e) => {
    var el = document.createElement('textarea');
    // Set value (string to be copied)
    el.value = $(e.currentTarget).data('value');
    // Set non-editable to avoid focus and move outside of view
    el.setAttribute('readonly', '');
    el.style = { position: 'absolute', left: '-9999px' };
    document.body.appendChild(el);
    // Select text inside element
    el.select();
    // Copy text to clipboard
    document.execCommand('copy');
    // Remove temporary element
    document.body.removeChild(el);
  });
});
