I’m not sure if you guys are still interested in a phone input, but I’ve put together a little plugin based on International Telephone Input by jackocnr.
The validation is done simply by Javascript “onblur” event. If the phone is not valid it will be just erased.
This is the first “release” of the plugin and it’s working quite nice on a personal project. There is no documentation (so far) – sorry.
If anybody has any ideas or want to help out, just let me know 🙂
