Javascript validating phone number field

Google's common Java, C and Java Script library for parsing, formatting, and validating international phone numbers.The Java version is optimized for running on smartphones, and is used by the Android framework since 4.0 (Ice Cream Sandwich).The idea is to create a set of “validation descriptors” associated with each element in a form.

When there are many fields in the form, the Java Script validation becomes too complex.Basically our validate Phone function takes an HTML text input field and a format type, strips all non-digits from the number and validates based on the cleansed string lenght.This would need to be updated for international numbers, or to allow users to enter phone numbers using letter representation.The OP should consult ITU recommendations before proceeding.That allows characters ( ) which cannot be dialled.

Each field in the form can have zero one or more validations. More info & downloads where Do My Validation One() and Do My Validation Two() are custom functions for validation.
