提供空值时不呈现 PayPal 借记卡或信用卡

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，则不再呈现表单

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 有什么办法可以有条件地将 email_address 属性添加到付款人中吗？或者您对此问题有其他解决方案吗？

谢谢。

                return actions.order.create(order);
            },
