Checkout validation and API
This module contains functions to validate and mask checkout form fields such as credit card fields.
API
validatePaymentDetails( paymentDetails, paymentType )
Returns an object containing the errors for each field. For example the returned object might look like this:
const error = {
number: [ 'Invalid credit card' ],
};
If there are any missing fields, there are no errors for that field.
getCreditCardType( number )
Returns credit card brand for a given card number
maskField( fieldName, previousValue, nextValue )
Returns a masked input value for the given field based on the current value and the next value to replace it with.
unmaskField( fieldName, previousValue, nextValue )
Returns an unmasked input value that is meant to be used within the program rather than displayed to the user.
