PayPal借记卡或信用卡在提供空值时不呈现

Question

我正在集成PayPal，但我确实遇到了一个问题：在下面的代码中，如果$("#DonorEmailID"(.val((为空，则表单将不再呈现

paypal.Buttons({
style: {
layout:  'vertical',
shape: 'rect',
height: 36
},
createOrder: function (data, actions) {
return actions.order.create({
//https://developer.paypal.com/docs/checkout/integration-features/standard-card-fields/
payer: {
email_address: $("#DonorEmailID").val(),
phone: {
phone_type: "MOBILE",
phone_number: {
national_number: "14082508100"
}
}
},
application_context: {
shipping_preference: 'NO_SHIPPING'
},
purchase_units: [{
description: getPurchaseDescription(),
amount: {
value: $("#Amount").val()
}
}]
});
},

演示视频：https://www.screencast.com/t/xdENMuUbcbWu有没有办法将email_address属性有条件地添加到付款人？或者你有其他解决方案吗？

谢谢。
