Javascript：將簡單的節點數組（帶有指向父節點的指針）轉換為嵌套的數據結構

Question

我已經閱讀了許多解決此問題的方法，例如正在嘗試使用數組到樹

給定此數據：

[
  {
    "_id": 33,
    "parent": null,
    "name": "Wealth and Investment Management and Insurance",
    "code": "wm-0001",
    "__v": 0
  },
  {
    "_id": 34,
    "parent": null,
    "name": "Corporate and Investment Banking",
    "code": "cib-0001",
    "__v": 0
  },
  {
    "_id": 35,
    "parent": 33,
    "name": "WIMI Business Unit 1",
    "code": "WIMBU-0001",
    "__v": 0
  }
]

並使用此代碼

var arrayToTree = require('array-to-tree');
var tree = arrayToTree(data, {
            parentProperty: 'parent',
            customID: '_id'
        });

我不明白為什么孤兒會成為孤兒？ 即我回來了

[ { _id: 33,
    parent: null,
    name: 'Wealth and Investment Management and Insurance',
    code: 'wm-0001',
    __v: 0 },
  { _id: 34,
    parent: null,
    name: 'Corporate and Investment Banking',
    code: 'cib-0001',
    __v: 0 } ]

Answer 1

似乎如果_id為Number類型，則array-to-tree不知道該怎么做；

更改此選項會將平面數組轉換為樹結構。

您可以遍歷數組將鍵 _id / parent轉換為string如果它們是number ；

如果您需要，我只會對其進行編輯（但以上方法可以解決）
