How to detect and validate credit card numbers in jQuery?

Question

I am trying to control input field using jQuery previously I had only numbers and could use $(this).autoNumeric(), now I have come around where it is required to change the input field in form of 'Numbers dash Numbers'.
i.e:- 1.343-45.643

Is there anything similar to autoNumeric which can do my work apart from writing my own regex and jquery method.

Query Credit Card Validator is written in CoffeeScript and (surprise, surprise!) is a jQuery plugin. It analyses the card number in the input field on which it was called, and returns an object with four properties:

card_type — an object with the below properties, or null if card type unknown
name — one of the strings describing the card type, eg visa
pattern — regular expression used to match the card type, eg /^4/
length — a list of valid lengths for the card type, eg [13, 16]
valid — true if the number is valid, false otherwise
length_valid — true if the number length is valid, false otherwise
luhn_valid — true if the Luhn checksum is correct, false otherwise
