import * as Payment from "payment";

const input = document.getElementById('input') as HTMLInputElement;

Payment.restrictNumeric(input);
Payment.formatCardNumber(input);
Payment.formatCardExpiry(input);
Payment.formatCardCVC(input);

const card = "1234 5678 9012 3456";

const cardType = Payment.fns.cardType(card);
Payment.fns.validateCardNumber(card);
Payment.fns.validateCardExpiry("1 / 20");
Payment.fns.validateCardExpiry("1", "20");
Payment.fns.validateCardCVC("123", cardType);

componentDidMount() {
    const { number, expiration, cvc, zip } = this.refs

    Payment.formatCardNumber(ReactDOM.findDOMNode(number).querySelector('input'))
    Payment.formatCardExpiry(ReactDOM.findDOMNode(expiration).querySelector('input'))
    Payment.formatCardCVC(ReactDOM.findDOMNode(cvc).querySelector('input'))

    if (zip) {
      Payment.restrictNumeric(ReactDOM.findDOMNode(zip).querySelector('input'))
    }
  }
