使用jQuery复制select2选择时出现的问题

var originalSelect = $('#originalSelect');
var clonedSelect = originalSelect.clone();
originalSelect.select2('destroy');
clonedSelect.select2();

var originalSelect = $('#originalSelect');
var clonedSelect = originalSelect.clone();
originalSelect.select2('destroy');
clonedSelect.select2();

originalSelect.on('change', function() {
  clonedSelect.val($(this).val()).trigger('change');
});

var originalSelect = $('#originalSelect');
var clonedSelect = originalSelect.clone();
originalSelect.select2('destroy');
clonedSelect.select2();

originalSelect.on('change', function() {
  clonedSelect.val($(this).val()).trigger('change');
});

originalSelect.on('select2:select', function(e) {
  var data = e.params.data;
  clonedSelect.append(new Option(data.text, data.id, false, false)).trigger('change');
});
