For payment requests that request shipping information, and for which shipping options are offered, the shippingoptionchange event is sent to the PaymentRequest whenever the user chooses a shipping option from the list of available options. The string identifying the currently-selected shipping option can be found in the shippingOption 特性。

范例

This code snippet sets up a handler for the shippingoptionchange event. The code recalculates the total charge for the payment based on the selected shipping option. For example, if there are three options (such as "Free ground shipping", "2-day air", and "Next day"), each time the user chooses one of those options, this event handler is called to recalculate the total based on the changed shipping option.

paymentRequest.addEventListener("shippingoptionchange", event => {
  const value = calculateNewTotal(paymentRequest.shippingOption);
  const total = {
    currency: "EUR",
    label: "Total due",
    值，
  };
  event.updateWith({ total });
}, false);

After caling a custom function, calculateNewTotal() , to compute the updated total based on the newly-selected shipping option as specified by the shippingOption . The revised total is submitted back to the payment request by calling the event's updateWith() 方法。

You can also create an event handler for shippingoptionchange using its corresponding event handler property, onshippingoptionchange :

paymentRequest.onshippingoptionchange = event => {
  const value = calculateNewTotal(paymentRequest.shippingOption);
  const total = {
    currency: "EUR",
    label: "Total due",
    值，
  };
  event.updateWith({ total });
};
