PaymentMethodChangeEvent: methodDetails property
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The read-only methodDetails
property of the PaymentMethodChangeEvent
interface is an object
containing any data the payment handler may provide to describe the change the user
has made to their payment method. The value is null
if no details
are available.
Value
An object containing any data needed to describe the changes made to the payment
method. The contents vary depending on the actual payment method chosen, so you will
need to refer to the methodName
property first, then interpret the methodDetails
after that.
The default value is null
, indicating that no additional details are
available.
Examples
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.
js
request.onpaymentmethodchange = (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 discount = calculateDiscount(ev.methodDetails);
Object.assign(newStuff, discount);
break;
}
}
}
// finally…
ev.updateWith(newStuff);
};
const response = await request.show();
Note that the methodDetails
property is being used by the calculateDiscount()
function to compute any payment discount, then updateWith()
is called to update the event with the computed update.
