PaymentRequest.onshippingoptionchange

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

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

Syntax

PaymentRequest.addEventListener('shippingoptionchange', shippingOptionChangeEvent => { ... });

PaymentRequest.onshippingoptionchange = function(shippingOptionChangeEvent) { ... };

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().

// 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);
      console.log(details.error);
    }
    // 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));
});
