<h1>Example: Country sync</h1>
<p>Use static getCountryData method to create a separate country dropdown for an address form, and then listen for change events to keep the two dropdowns in sync.</p>
<h2>Markup</h2>
<pre><code class="language-markup"><div class="form-item">
<label>Telephone number</label>
<input id="phone" type="tel">
</div>
<div class="form-item">
<label>Address</label>
<input type="text" placeholder="House name/number">
<input type="text" placeholder="City">
<input type="text" placeholder="State">
<input type="text" placeholder="Zip code">
<select id="address-country"></select>
</div></code></pre>
<h2>Code</h2>
<pre><code class="language-javascript">// get the country data from the plugin
var countryData = window.intlTelInputGlobals.getCountryData(),
input = document.querySelector("#phone"),
addressDropdown = document.querySelector("#address-country");
// init plugin
var iti = window.intlTelInput(input, {
utilsScript: "../../build/js/utils.js?1541153396801" // just for formatting/placeholders etc
});
// populate the country dropdown
for (var i = 0; i < countryData.length; i++) {
var country = countryData[i];
var optionNode = document.createElement("option");
optionNode.value = country.iso2;
var textNode = document.createTextNode(country.name);
optionNode.appendChild(textNode);
addressDropdown.appendChild(optionNode);
}
// set it's initial value
addressDropdown.value = iti.getSelectedCountryData().iso2;
// listen to the telephone input for changes
input.addEventListener('countrychange', function(e) {
addressDropdown.value = iti.getSelectedCountryData().iso2;
});
// listen to the address dropdown for changes
addressDropdown.addEventListener('change', function() {
iti.setCountry(this.value);
});
