detect-card-js

Automatically detect payment card types with this JQuery plugin

Usage

It's fairly simple:

1. Locate your card number input field with JQuery i.e. $('input#cardNumber')
2. Call .detectCard() on the your input field
3. Listen for the cardChange event

Example

$("input#cardNumber").detectCard().on("cardChange", function(e, card) {

  // Assuming input of card number: 4111 111 1111 1111
  console.log(card.type);  // => "visa"
});

Custom supported card types

You can also choose which card types you would like to support

$("input#cardNumber").detectCard({ supported: ['visa', 'mastercard', 'maestro']});
$("input#cardNumber").on("cardChange", function(e, card) {

  // Assuming input of card number: 4111 111 1111 1111
  console.log(card.type);      // => "visa"
  console.log(card.supported); // => true
});
