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 property of the PaymentRequest interface returns the ID attribute of the shipping option selected by the user. This option is only present when the requestShipping option is set to true in the PaymentOptions object passed to the PaymentRequest constructor.
In the example below, the shippingoptionchange event is called. It calls updateDetails() to toggle the shipping method between "standard" and "express".
const payment = new PaymentRequest(supportedInstruments, details, options);
request.addEventListener("shippingoptionchange", (evt) => {
evt.updateWith(
new Promise((resolve, reject) => {
updateDetails(details, request.shippingOption, resolve, reject);
}),
);
});
payment
.show()
.then((paymentResponse) => {
})
.catch((err) => {
console.error("Uh oh, something bad happened", err.message);
});
function updateDetails(details, shippingOption, resolve, reject) {
let selectedShippingOption;
let otherShippingOption;
if (shippingOption === "standard") {
selectedShippingOption = details.shippingOptions[0];
otherShippingOption = details.shippingOptions[1];
details.total.amount.value = "55.00";
} else if (shippingOption === "express") {
selectedShippingOption = details.shippingOptions[1];
otherShippingOption = details.shippingOptions[0];
details.total.amount.value = "67.00";
} else {
reject(`Unknown shipping option '${shippingOption}'`);
return;
}
selectedShippingOption.selected = true;
otherShippingOption.selected = false;
details.displayItems.splice(2, 1, selectedShippingOption);
resolve(details);
}
