Javascript Braintree-谷歌支付按钮不显示
我只是将此代码剪切并粘贴到一个名为payg.html的html文件上： 我将“jsfiddel html部分”粘贴到页面的开头Javascript Braintree-谷歌支付按钮不显示,javascript,braintree,google-pay,Javascript,Braintree,Google Pay,我只是将此代码剪切并粘贴到一个名为payg.html的html文件上： 我将“jsfiddel html部分”粘贴到页面的开头 <div id="container"></div> <script async src="https://pay.google.com/gp/p/js/pay.js" onload="onGooglePayLoaded()"></script> 按钮根本不显示，本例似乎不需要API或自定义私钥/公钥来显示按钮

致以最诚挚的问候。其中一个可能的原因可能是与您的谷歌帐户相关的国家 我已经更新了您的JSFIDLE，使其包含一个
console.log函数onGooglePayLoaded（）{
const paymentsClient=getGooglePaymentsClient（）；
paymentsClient.isReadyToPay（getGoogleIsReadyToPayRequest（））
.然后（功能（响应）{
if（response.result）{
addGooglePayButton（）；
//@todo在确认站点功能后预取付款数据以提高性能
//预取GooglePaymentData（）；
}其他{
console.log（“未准备好付款”）；
}
})
.catch（函数（err）{
//在开发人员控制台中显示调试错误
控制台错误（err）；
});
}
验证它是否与国家有关的一种方法是，在其中一个中创建一个新的Google帐户，然后重试。原因之一可能是与您的Google帐户关联的国家 我已经更新了您的JSFIDLE，使其包含一个
