错误：“托管字段付款已在进行中。”
我已经从这个 PayPal 文档中复制了它，并在 SDK URL 中传递了一个正确的沙箱 clientID。
if (paypal.HostedFields.isEligible()) {
paypal.HostedFields.render({
createOrder: function () {return "order-ID";}, // replace order-ID with the order ID
styles: {
'input': {
'font-size': '17px',
'font-family': 'helvetica, tahoma, calibri, sans-serif',
'color': '#3a3a3a'
},
':focus': {
'color': 'black'
}
},
fields: {
number: {
selector: '#card-number',
placeholder: 'card number'
},
cvv: {
selector: '#cvv',
placeholder: 'card security number'
},
expirationDate: {

placeholder: 'mm/yy'
}
}
}).then(function (hf) {
$('#my-sample-form').submit(function (event) {
event.preventDefault();
hf.submit({
// Cardholder Name
cardholderName: document.getElementById('card-holder-name').value,
