i18n libphonenumber mask (with in-hand country code)

international phone number mask

/* 
   This is using the JS port of Google's libphonenumber. 
   As far as I know, though, all of the APIs are the same or similar 
*/
 
// I just hardcoded "US" as the country, but of course you can use any country iso code
var ctry = 'US';

var exampleNumber = i18n.phonenumbers.PhoneNumberUtil.getInstance()
                    .getExampleNumberForType(ctry, i18n.phonenumbers.PhoneNumberType.MOBILE); // returns PhoneNumber instance

exampleNumber.values_ // I believe the trailing underscore means this is undocumented... but I like to live dangerously
// Well, I also haven't unearthed an API call to actually get the number text, or to format a number from a PhoneNumber instance
// I know the AsYouTypeFormatter would do it, but you have to enter one character at a time 
// Returns an object {1: <countryCode>, 2: <phoneNumber>}, both are Numbers

// Can use any of the provided formatting fns here
// Example output: "+1 201-555-5555"
var formattedNumber = formatNumberForMobileDialing(ctry, exampleNumber.values_[2].toString());

// You may also want to L18n the placeholder character, but I haven't looked into what's expected in other languages    
// Example output: "+x xxx-xxx-xxxx"
var mask = formattedNumber.replace(/\d/g, 'x'); 

I ended up not using this, and so looked no further into cleaning this up. I really just wanted to know I could.

Great idea, I used it for my Angular 2/Ionic app. Thanks!

I used this as well, still works, thanks for the inspiration!!

awesome

'_' means private field :)
