javascript - 如何从嵌套的 JSON 数据中获取值

Question

我正在尝试从下面的嵌套 JSON 数据中获取值。具体来说，付款捕获的 id 值 0TA12948FV40723B 是我需要的值。

我尝试使用以下代码来检索该值。

details.purchase_units.payments.captures.id

details.purchase_units.payments[0].captures.id

但我不断收到 console.log 错误:“无法捕获订单”

JSON 数据

}

Answer 1

由于purchase_units和captures是数组:

details.purchase_units[0].payments.captures[0].id
