Javascript 带父参数的JS Reduce

我试图用reduce函数来解决我的最后一个问题，将嵌套的JSON对象转换成一个平面列表，以便更轻松地进行搜索

以下面的JSON为例

    {
  "MovementPatterns": [
    {
      "Id": "",
      "Name": "Warm-up",
      "Exercises": [
        {
          "Id": "",
          "Name": "Lizard Stretch",
          "Level": 1,
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Pigeon Stretch",
          "Level": 1,
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Core Hold",
          "Level": 1,
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Superman",
          "Level": 1,
          "EquipmentRequired": ""
        }
      ]
    },
    {
      "Name": "Horizontal Push",
      "Id": "",
      "Exercises": [
        {
          "Id": "",
          "Name": "Wall Push-up",
          "Level": 0,
          "VideoUrl": "",
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Push-up",
          "Level": 1,
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Tap Push-up",
          "Level": 2,
          "EquipmentRequired": ""
        },
        {
          "Id": "",
          "Name": "Explosive Push-up",
          "Level": 3,
          "EquipmentRequired": ""
        }
      ]
    }
  ]
}

我使用了以下代码：

const exercises = data.MovementPatterns.reduce(
  (a, {Exercises}) => [...a, ...Exercises, ...a],
  [],
);

为了将每个动作模式中的所有练习都变成一个纯粹的练习列表…这很好，但我现在需要在每个练习的JSON中包含父动作模式ID，例如

[
        {
          "Id": "",
          "Name": "Lizard Stretch",
          "Level": 1,
          "MovementPatternId": 1,
          "EquipmentRequired": ""
        },
....
        {
          "Id": "",
          "Name": "Wall Push-up",
          "Level": 1,
          "MovementPatternId": 2,
          "EquipmentRequired": ""
        },
]

有人能帮我弄清楚如何使用我的reduce函数做到这一点吗：）

谢谢

你就快到了。只需将父级的

Id

作为

MovementPatternId

附加到

练习的每个元素中即可

const exercises = ab.MovementPatterns.reduce(
  (a, { Exercises, Id }) => [
    ...a,
    ...Exercises.map(e => ({ ...e, MovementPatternId: Id }))
  ],
  []
);

你差一点就到了。只需将父级的
Id
作为
MovementPatternId
附加到
练习的每个元素中即可

const exercises = ab.MovementPatterns.reduce(
  (a, { Exercises, Id }) => [
    ...a,
    ...Exercises.map(e => ({ ...e, MovementPatternId: Id }))
  ],
  []
);

真的很有帮助…真的很有帮助。。。
