Credit Card data validator

A JavaScript implementation

Can check if only the credit card number is valid, or also the date, based on the current date.

Usage:

Just using the number, just valid the number:

var validator = new Bluefish.CreditCardValidator("1234123412341234");
console.log(validator.valid());

Using number, year and month:

var validator = new Bluefish.CreditCardValidator("1234123412341234",2012,11);
console.log(validator.validNumber());
console.log(validator.validDate());
console.log(validator.valid());

Formatting number:

var validator = new Bluefish.CreditCardValidator("1234123412341234");
console.log(validator.formatNumber()) => "1234-1234-1234-1234"
