JsonPath 从其他数组中获取数组元素

Question

我刚刚了解 JsonPath。我正在使用 jsonpath.com 并在其中粘贴下面的示例，尝试根据 Donna 的名字进行搜索。

类似于：

$.prizes[?(@.laureates.firstname == Donna)]

但这不起作用。是否可以使用 ?(@.) 类型的表达式来搜索名字 Donna 并使结果为：

[
  {
     "id": "962",
     "firstname": "Donna",
     "surname": "Strickland",
     "motivation": "\"for their method of generating high-intensity, ultra-short optical pulses\"",
     "share": "4"
  }
]

原始数据如下：

{
  "prizes": [
    {
      "year": "2018",
      "category": "physics",
      "overallMotivation": "\"for groundbreaking inventions in the field of laser physics\"",
      "laureates": [
        {
          "id": "960",
          "firstname": "Arthur",
          "surname": "Ashkin",
          "motivation": "\"for the optical tweezers and their application to biological systems\"",
          "share": "2"
        },
        {
          "id": "961",
          "firstname": "Gérard",
          "surname": "Mourou",
          "motivation": "\"for their method of generating high-intensity, ultra-short optical pulses\"",
          "share": "4"
        },
        {
          "id": "962",
          "firstname": "Donna",
          "surname": "Strickland",
          "motivation": "\"for their method of generating high-intensity, ultra-short optical pulses\"",
          "share": "4"
        }
      ]
    }
  ]
}
