var card = new CardType();
card.validate('4000000000000002');
//=> { valid: true, validLength: true, isValidLuhn: true, cardType: 'visa' }

Global

If you are not using AMD then CardType is exposed as a global variable.

<script src='/path/to/cardtype.js'></script>
<script>
    var card = new CardType();
    CardType.validate('4000000000000002');
    //=> { valid: true, validLength: true, isValidLuhn: true, cardType: 'visa' }
</script>

Accepted card types

An optional accepted cards array can be passed to the constuctor to restrict which cards are validated:

var card = new CardType([ 'amex', 'discover' ]);
card.validate('6011000000000004'); // Discover
//=> { valid: true, validLength: true, isValidLuhn: true, cardType: 'discover' }
card.validate('4000000000000002'); // Visa
//=> false
