带有国家/地区同步功能的国际电话输入插件不起作用

Question

I using intlTelInput for the telephone & mobile field on asp.net webform website.

At present i am using it as a basic plugin as show in this example

var input = $("#ContentPlaceHolder1_txtPhone"), output = $("#output");
            var country = $("#ContentPlaceHolder1_ddCountry");

            input.intlTelInput({
                preferredCountries: ['ae'],
                autoHideDialCode: true,
                nationalMode: false,
                utilsScript: "../../Scripts/phone/js/utils.js" // just for formatting/placeholders etc
            });

Now i am trying to sync it with the Country drop-down so that when user select the country it then automatically select the Telephone Fields & Mobile field on web-form with the country in telephone fields.

I tried to use this example but it is not working either it break the plugin or it downt work

http://intl-tel-input.com/node_modules/intl-tel-input/examples/gen/country-sync.html

Code which i tried

var countryData = $.fn.intlTelInput.getCountryData(),
                telInput = $("#ContentPlaceHolder1_txtPhone"),
                addressDropdown = $("#ContentPlaceHolder1_ddCountry");

            // set it's initial value
            //var initialCountry = telInput.intlTelInput("getSelectedCountryData").iso2;
            //addressDropdown.val(initialCountry);
            // listen to the telephone input for changes
            telInput.on("countrychange", function (e, countryData) {
                addressDropdown.val(countryData.iso2);
            });
            // listen to the address dropdown for changes
            addressDropdown.change(function () {
                telInput.intlTelInput("setCountry", $(this).val());
            });

I have place code on codepen http://codepen.io/anon/pen/wgzppg .

I am not sure where i am doing it wrong. i tried few thing without any luck.

I pull data for country dropdown from database table not the plugin so that may be causing issue somewhere. but country code are matching also.

Answer 1

I solved it problem seems to be with the countryCode as was getting countryCode in UpperCase and changing that to lower case seemed to have fixed the issue
