The shippingaddresschange event is sent to the PaymentRequest object when the user selects a shipping address or changes details of their shipping address.

This event is not cancelable and does not bubble.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener("shippingaddresschange", (event) => {});

onshippingaddresschange = (event) => {};

A PaymentRequestUpdateEvent. Inherits from Event.

Provides only the properties inherited from Event.

Depending on the browser, the shipping address information may be redacted for privacy reasons. That is, the PaymentAddress which contains the shipping address may have some portions of its content altered, obscured, or left out entirely in order to prevent identifying the user without their consent (since if they choose to have you ship products to them, you'll need their address).

In this example, a handler for the shippingaddresschange event is set up to validate that the address meets requirements set by the web application.

const paymentRequest = new PaymentRequest(methodData, details, options);

paymentRequest.addEventListener(
  "shippingaddresschange",
  (event) => {
    let detailsUpdate = checkAddress(paymentRequest.shippingAddress);
    event.updateWith(detailsUpdate);
  },
  false,
);

const checkAddress = (theAddress) => {
  let detailsUpdate = {};

  // Check the address, return an object with any changes or errors.

  return detailsUpdate;
};

You can also establish a handler for shippingaddresschange using the onshippingaddresschange event handler property:

paymentRequest.onshippingaddresschange = (event) => {
  let detailsUpdate = checkAddress(paymentRequest.shippingAddress);
  event.updateWith(detailsUpdate);
};
