Example: Validation

Use public isValidNumber method (utilising Google's libphonenumber) to validate the telephone number on the change event.

Markup

<input id="phone" type="tel">
<span id="valid-msg" class="hide">✓ Valid</span>
<span id="error-msg" class="hide">Invalid number</span>

Code

var telInput = $("#phone"),
  errorMsg = $("#error-msg"),
  validMsg = $("#valid-msg");

// initialise plugin
telInput.intlTelInput({
  utilsScript: "../../lib/libphonenumber/build/utils.js"
});

// on blur: validate
telInput.blur(function() {
  if ($.trim(telInput.val())) {
    if (telInput.intlTelInput("isValidNumber")) {
      validMsg.removeClass("hide");
    } else {
      telInput.addClass("error");
      errorMsg.removeClass("hide");
      validMsg.addClass("hide");
    }
  }
});

// on keydown: reset
telInput.keydown(function() {
  telInput.removeClass("error");
  errorMsg.addClass("hide");
  validMsg.addClass("hide");
});
