PaymentRequest.onshippingoptionchange

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The onshippingoptionchange event of the PaymentRequest interface is fired whenever the user changes a shipping option. 

syntax

JavaScript
PaymentRequest.addEventListener('shippingaddresschange', shippingaddresschangeevent => { ... });

PaymentRequest.onshippingaddresschange = function(shippingaddresschangeevent) { ... };

Examples

The shippingoptionchange event is triggered by a user-agent controlled interaction. If the option stored by the user agent changes at any time during a payment process, the event is triggered. To make sure an updated option is included when sending payment information to the server, you should add event listeners for a PaymentRequest object after instantiation, but before the call to show().

JavaScript
// Initialization of PaymentRequest arguments are excerpted for clarity.
var request = new PaymentRequest(supportedInstruments, details, options);

// When user selects a shipping address
request.addEventListener('shippingaddresschange', e => {
  e.updateWith(((details, addr) => {
    var shippingOption = {
      id: '',
      label: '',
      amount: { currency: 'USD', value: '0.00' },
      selected: true
    };
    // Shipping to US is supported
    if (addr.country === 'US') {
      shippingOption.id = 'us';
      shippingOption.label = 'Standard shipping in US';
      shippingOption.amount.value = '0.00';
      details.total.amount.value = '55.00';
    // Shipping to JP is supported
    } else if (addr.country === 'JP') {
      shippingOption.id = 'jp';
      shippingOption.label = 'International shipping';
      shippingOption.amount.value = '10.00';
      details.total.amount.value = '65.00';
    // Shipping to elsewhere is unsupported
    } else {
      // Empty array indicates rejection of the address
      details.shippingOptions = [];
      return Promise.resolve(details);
    }
    // Hardcode for simplicity
    if (details.displayItems.length === 2) {
      details.displayItems[2] = shippingOption;
    } else {
      details.displayItems.push(shippingOption);
    }
    details.shippingOptions = [shippingOption];

    return Promise.resolve(details);
  })(details, request.shippingAddress));
});
