我现在被困在这一点上。我以前从未使用过 Braintree API。问题是当我点击提交按钮时,它会显示带有我的 payment_method_nonce 的警报框。这意味着我成功地从客户那里获得了 payment_method_nonce,但问题是我不知道如何提交带有这个 payment_method_nonce 的表单。这个客户端 sdk 是用 jquery 编写的。我尝试了几种提交表单的方法,但我不知道在提交表单时如何获得“payment_method_nonce”。我厌倦了添加隐藏类型字段。甚至那个隐藏的类型字段也没有出现。请帮忙。这是jquery代码。我只想知道如何在 jquery 中使用“payment_method_nonce”提交表单。
