You'll need to add the code below in your default-country-ip.js file.
$("#phone").intlTelInput({
initialCountry: "auto",
geoIpLookup: function(callback) {
$.get('//ipinfo.io', function() {}, "jsonp").always(function(resp) {
var countryCode = (resp && resp.country) ? resp.country : "";
callback(countryCode);
});
},
utilsScript: "js/utils.js" // just for formatting/placeholders etc
});
var telInput = $("#phone"),
errorMsg = $("#error-msg"),
validMsg = $("#valid-msg");
// initialise plugin
telInput.intlTelInput({
utilsScript: "js/utils.js"
});
var reset = function() {
telInput.removeClass("error");
errorMsg.addClass("hide");
validMsg.addClass("hide");
};
// on blur: validate
telInput.blur(function() {
reset();
if ($.trim(telInput.val())) {
if (telInput.intlTelInput("isValidNumber")) {
validMsg.removeClass("hide");
} else {
telInput.addClass("error");
errorMsg.removeClass("hide");
}
}
});
// on keyup / change flag: reset
telInput.on("keyup change", reset);
