jQuery Credit Card Validator detects and validates credit card numbers. It’ll tell you the detected credit card type and whether the number length and Luhn checksum are valid for the type of card.

npm i jquery-creditcardvalidator

Download the latest jquery.creditCardValidator.js.

The latest stable version is always in the master branch. If you need previous versions, you’ll find them on the releases page.

Do not use any branches other than master. Branches starting with release/ are development branches and they will most likely be broken.

Run validation every time a field value changes:

$('#cc_number').validateCreditCard(function(result) {
    if (result.valid) {
        $(this).addClass('cc-valid');
    } else {
        $(this).removeClass('cc-valid');
    }
});

Run validation once:

const result = $('#cc_number').validateCreditCard();

if (result.valid) {
    $(this).addClass('cc-valid');
} else {
    $(this).removeClass('cc-valid');
}
