javascript - 获取数组父键或与嵌套项组合

Question

我有以下带数组的对象:

{
  "brands": [
    "accessible-icon",
    "accusoft",
    "adn",
    "adobe",
    "adversal",
  ],
  "regular": [
    "address-book",
    "address-card",
    "angry",
    "bell",
  ],
  "solid": [
    "ad",
    "address-book",
    "address-card",
    "adjust",
    "air-freshener",
    "align-center",
  ]
}

我有一个函数，它从一个数组组中返回一个项目。我必须找出该项目是从哪个数组组中提取的。据我了解，不可能在 js 中查找父键？

获取父键是最理想的，否则，是否可以将父键添加到所有嵌套项中？例如，brands 数组中的嵌套项将变为:

 "brands": [
    "brands-accessible-icon",
    "brands-accusoft",
    "brands-adn",
    "brands-adobe",
    "brands-adversal",
  ],

然后我可以使用正则表达式来提取brands。

最初我将对象转换为具有数组组的对象。以下是名为 brands 的对象之一的示例:

{
  "faAccessibleIcon": {
    "prefix": "fab",
    "iconName": "accessible-icon",
    "icon": [
      448,
      512,
      [],
      "f368",
    ]
  },
  "faAccusoft": {
    "prefix": "fab",
    "iconName": "accusoft",
    "icon": [
      640,
      512,
      [],
      "f369",
    ]
  },
  "faAcquisitionsIncorporated": {
    "prefix": "fab",
    "iconName": "acquisitions-incorporated",
    "icon": [
      344,
      512,
      [],
      "f6af",
    ]
  },
}

然后我简化对象:

const array = {
  "brands": Object.keys(brands).map(e=> brands[e].iconName),
  "regular": Object.keys(regular).map(e=> regular[e].iconName),
  "solid": Object.keys(solid).map(e=> solid[e].iconName),
};

并且 array 成为在我的问题顶部看到的带有数组的对象。数组结构必须保持这样。有没有办法结合 prefix 和 iconName 并获得 brands-accessible-icon, brands-accusoft 等, 在嵌套数组项中，对于每组数组？

您可以获取对象的键并在数组中找到值。

const getKey = (object, value) => Object.keys(object).find(k => object[k].includes(value));

var data = { brands: ["accessible-icon", "accusoft", "adn", "adobe", "adversal"], regular: ["address-book", "address-card", "angry", "bell"], solid: ["ad", "address-book", "address-card", "adjust", "air-freshener", "align-center"] };

console.log(getKey(data, "bell"));
