Klasapublic class CreditCardValidator
DziedziczenieCreditCardValidator Inheritance Validator Inheritance EventDispatcher Inheritance Object

Wersja języka: ActionScript 3.0
Wersja produktu: Flex 3
Wersje środowiska wykonawczego: Flash Player 9, AIR 1.1

The CreditCardValidator class validates that a credit card number is the correct length, has the correct prefix, and passes the Luhn mod10 algorithm for the specified card type. This validator does not check whether the credit card is an actual active credit card account.

You can specify the input to the CreditCardValidator in two ways:

  • Use the cardNumberSource and cardNumberProperty properties to specify the location of the credit card number, and the cardTypeSource and cardTypeProperty properties to specify the location of the credit card type to validate.
  • Use the source and property properties to specify a single Object. The Object should contain the following fields:
    • cardType - Specifies the type of credit card being validated.

      In MXML, use the values: "American Express", "Diners Club", "Discover", "MasterCard", or "Visa".

      In ActionScript, use the static constants CreditCardValidatorCardType.MASTER_CARD, CreditCardValidatorCardType.VISA, or CreditCardValidatorCardType.AMERICAN_EXPRESS CreditCardValidatorCardType.DISCOVER, or CreditCardValidatorCardType.DINERS_CLUB.

    • cardNumber - Specifies the number of the card being validated.

To perform the validation, it uses the following guidelines:

Length:

  1. Visa: 13 or 16 digits
  2. MasterCard: 16 digits
  3. Discover: 16 digits
  4. American Express: 15 digits
  5. Diners Club: 14 digits or 16 digits if it also functions as MasterCard
Prefix:
  1. Visa: 4
  2. MasterCard: 51 to 55
  3. Discover: 6011
  4. American Express: 34 or 37
  5. Diners Club: 300 to 305, 36 or 38, 51 to 55

Treść dokumentacji języka ActionScript 3.0 wyświetlana w języku angielskim

Niektóre części dokumentacji języka ActionScript 3.0 nie są przetłumaczone na poszczególne języki. Gdy element nie jest przetłumaczony na dany język, jest wyświetlany tekst angielski. Na przykład opis klasy ga.controls.HelpBox nie jest przetłumaczony na żaden dodatkowy język. Z tego powodu polska wersja dokumentacji zawiera opis klasy ga.controls.HelpBox w języku angielskim.
