我正在尝试运行https://www.youtube.com/watch?v=yelPlCVZLEE上所示的付款请求API的示例。
我遵循了他们描述的过程,并且我还运行了以下代码:
function go() {
console.log('Pay');
var request = new PaymentRequest([{
supportedMethods:['urn:payment:visa','urn:payment:mc','urn:payment:amex']
}],
{
total: {
label: "Total due",
amount: { currencyCode: "USD", value: "60.00" }, // US$60.00
}
}
);
request.show()
.then(function(response) {
// process transaction response here
return response.complete(true);
})
.then(function() {
alert("Buy!");
})
.catch(function(e) {
alert(e.name);
});
}
并且出现以下错误:未捕获的ReferenceError:未定义PaymentRequest。
如果我从运行测试:
http://github.adrianba.net/paymentrequest-demo/tests/payment-tests.html
据说已经定义好了。
我做错了什么?
最佳答案
您链接的站点http://github.adrianba.net/paymentrequest-demo/tests/payment-tests.html提取一个文件:
<script src="../lib/paymentrequest.js"></script>
定义了自己的
PaymentRequest
实现:function PaymentRequest(methodData,details,options) {
// Constructor code
if(!Array.isArray(methodData) || methodData.length===0) throw new TypeError("methodData must be a non-empty sequence of PaymentMethodData");
methodData.forEach(d => {

要在Chrome中获取
PaymentRequest
,必须在chrome:// flags /#enable-experimental-web-platform-features中启用它关于javascript - 未定义PaymentRequest API,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/37856138/
