PaymentRequest: id プロパティ
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
id
は PaymentRequest
インターフェイスの読み取り専用プロパティで、特定の PaymentRequest
インスタンスに固有の識別子を返します。
PaymentRequest
のインスタンスを構築する際に、独自の id を指定することが可能です。指定されなかった場合、ブラウザーは自動的に id 値を UUID に設定します。
例
この例は、PaymentRequest
インスタンスに独自の ID を付与する方法を示します。
js
const details = {
id: "super-store-order-123-12312",
total: {
label: "Total due",
amount: { currency: "USD", value: "65.00" },
},
};
const request = new PaymentRequest(methodData, details);
console.log(request.id); // super-store-order-123-12312
The id
is then also available in the PaymentResponse
returned from the show()
method, but under the requestId
attribute.
js
const response = await request.show();
console.log(response.requestId === request.id);
// And in serialized form too
const json = response.toJSON();
console.log(json.requestId, response.requestId, request.id);
値
文字列です。
