PaymentRequest.shippingOption

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

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The shippingOption read-only attribute of the PaymentRequest interface returns either the id of a selected shipping option, null (if no shipping option was set to be selected) or a shipping option selected by the user. It is initially null by when no "selected" shipping options are provided.

This attribute is only populated if the constructor is called with the requestShipping flag set to true. If requestShipping was false (or missing),  shippingOption returns null, even the developer provides a  selected a shipping option.

Syntax

// Returns the id of the selected PaymentShippingOption
var shippingOption = request.shippingOption;

Example

In the example below, the PaymentRequest.onshippingoptionchange and the PaymentRequest.onshippingaoptionchange events are dispatched. In each calls to updateDetails()  are made, one using a promise, and the other with a plain JS object. This demotrates synchrounous and asynchronous updates to a payment sheet. 

const request = new PaymentRequest(methodData, details, options);
// Async update to details
request.onshippingaddresschange = ev => {
  ev.updateWith(checkShipping(request));
};
// Sync update to the total
request.onshippingoptionchange = ev => {
  const shippingOption = shippingOptions.find(
    option => option.id === request.id
  );
  const newTotal = {
    currency: "USD",
    label: "Total due",
    value: calculateNewTotal(shippingOption),
  };
  ev.updateWith({ ...details, total: newTotal });
};
async function checkShipping(request) {
  try {
    const json = request.shippingAddress.toJSON();

    await ensureCanShipTo(json);
    const { shippingOptions, total } = await calculateShipping(json);

    return { ...details, shippingOptions, total };
  } catch (err) {
    return { ...details, error: `Sorry! we can't ship to your address.` };
  }
}
