Country sync

This demo showcases two features of International Telephone Input. First, that you can access the plugin's country data using the static method getCountryData and use it for your own purposes e.g. to create your own country list for an address form. Second, that you can listen for custom JavaScript events triggered by the dropdown e.g. the countrychange event, which is triggered when the user selects a new country, and respond to that how you like e.g. to keep the two country dropdowns in sync with each other.



<div class="form-item">
  <label>Telephone number</label>

// set address dropdown's initial value

// listen to the telephone input for changes

  addressDropdown.value = iti.getSelectedCountryData().iso2;
