Web/API/PaymentMethodChangeEvent/methodName

Secure contextThis feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The read-only methodName property of the PaymentMethodChangeEvent interface is a string which uniquely identifies the payment handler currently selected by the user. The payment handler may be a payment technology, such as Apple Pay or Android Pay, and each payment handler may support multiple payment methods; changes to the payment method within the payment handler are described by the PaymentMethodChangeEvent.

Syntax

var methodName = paymentMethodChangeEvent.methodName;

Value

A DOMString which uniquely identifies the currently-selected payment handler. This may be a string chosen from the list of standardized payment method identifiers, or a URL used by the payment processing service. See Payment method identifiers in Payment Request API for more information.

The default value is the empty string, "".

Example

This example uses the paymentmethodchange event to watch for changes to the payment method selected for Apple Pay, in order to compute a discount if the user chooses to use a Visa card as their payment method.

request.onpaymentmethodchange = function(ev) {
  const { type: cardType } = ev.methodDetails;
  const newStuff = {};
  if (ev.methodName === "https://apple.com/apple-pay") {
    switch (cardType) {
      case "visa":
        // do Apple Pay specific handling for Visa card...
        // methodDetails contains the card information
        const result = calculateDiscount(ev.methodDetails);
        Object.assign(newStuff, result);
        break;
    }
  }
  // finally...
  ev.updateWith(newStuff);
};
const response = await request.show();
