<gold-cc-input>

gold-cc-input is a single-line text field with Material Design styling for entering a credit card number. As the user types, the number will be formatted by adding a space every 4 digits.

<gold-cc-input></gold-cc-input>

It may include an optional label, which by default is "Card number".

<gold-cc-input label="CC"></gold-cc-input>

Validation

The input can detect whether a credit card number is valid, and the type of credit card it is, using the Luhn checksum. See http://jquerycreditcardvalidator.com/ for more information.

The input can be automatically validated as the user is typing by using the auto-validate and required attributes. For manual validation, the element also has a validate() method, which returns the validity of the input as well sets any appropriate error messages and styles.

A list of allowable credit card types can be provided via the cardTypes property. Possible options, from cc-validator.js, are: amex, diners_club, discover, jcb, laser, maestro, mastercard, visa, visa_electron.

See Polymer.PaperInputBehavior for more API docs.

Styling

See Polymer.PaperInputContainer for a list of custom properties used to style this element.
