<h1>Example: Validation</h1>
<p>Use the isValidNumber method (which utilises Google's libphonenumber) to validate the telephone number on the blur event.</p>
<h2>Markup</h2>
<pre><code class="language-markup"><input id="phone" type="tel">
<span id="valid-msg" class="hide">✓ Valid</span>
<span id="error-msg" class="hide"></span>
</code></pre>
<h2>Code</h2>
<pre><code class="language-javascript">var input = document.querySelector("#phone"),
errorMsg = document.querySelector("#error-msg"),
validMsg = document.querySelector("#valid-msg");
// here, the index maps to the error code returned from getValidationError - see readme
var errorMap = [ "Invalid number", "Invalid country code", "Too short", "Too long", "Invalid number"];
// initialise plugin
var iti = window.intlTelInput(input, {
utilsScript: "../../build/js/utils.js?1541153396801"
});
var reset = function() {
input.classList.remove("error");
errorMsg.innerHTML = "";
errorMsg.classList.add("hide");
validMsg.classList.add("hide");
};
// on blur: validate
input.addEventListener('blur', function() {
reset();
if (input.value.trim()) {
if (iti.isValidNumber()) {
validMsg.classList.remove("hide");
} else {
input.classList.add("error");
var errorCode = iti.getValidationError();
errorMsg.innerHTML = errorMap[errorCode];
errorMsg.classList.remove("hide");
}
}
});
// on keyup / change flag: reset
input.addEventListener('change', reset);
input.addEventListener('keyup', reset);
</code></pre>
