我只是剪切&粘贴这个代码的html文件，我叫payg.html。https:/jsfiddle.netf1am0dr7
我把 "jsfiddel html部分 "粘贴在页面的开头。
<div id="container"></div>
<script async

onload="onGooglePayLoaded()"></script>
和 "jsfiddle javascript部分 "在下面和中间的位置

按钮根本不显示，这个例子似乎不需要API或自定义privatepublic key就能显示按钮。
你能帮帮我吗。
最好的祝愿。
其中一个可能的原因是由于你的谷歌账户关联的国家。
我已经更新了你的JSFiddle，包含了一个 console.log 声明。https:/jsfiddle.netge37h05t
function onGooglePayLoaded() {
const paymentsClient = getGooglePaymentsClient();
paymentsClient.isReadyToPay(getGoogleIsReadyToPayRequest())
.then(function(response) {
if (response.result) {
addGooglePayButton();
// @todo prefetch payment data to improve performance after confirming site functionality
// prefetchGooglePaymentData();
} else {
console.log('Not ready to pay');
}
})
.catch(function(err) {
// show error in developer console for debugging
console.error(err);
});
}
你可以用上面的链接再试一次，并检查控制台的输出？
有一种方法可以验证它是国家相关的是通过创建一个新的谷歌帐户在其中的一个 支持国 并以此再次尝试。
