Question

我有3个对象，其中包含有关svg图标（FontAwesome）的信息。每个对象都具有相同的结构，但是prefix属性具有不同的值。下面的对象使用fab作为前缀，第二个far和第三个fas作为前缀。

    ]
  },
}

我试图将上面看到的3个对象变成这样：

"brands": [
  "facebook",
  "twitter",
  "instagram",
],
"regular": [
  "arrow-up",
  "arrow-left",
  "arrow-right",
],
"solid": [
  "carrot",
  "cat",
  "dog",
],

棘手的部分还将前缀名称更改为数组的另一个值。 fab是品牌，far是常规品牌，fas是实体品牌。

我正在使用React并拥有Babel。这就是我到目前为止所拥有的...

const objects = [
    ...Object.values( fab ),
    ...Object.values( far ),
    ...Object.values( fas ),
]

它将所有对象转换为数组，但是我不确定如何获取所需的结构。

对于将前缀更改为名称，我相信这是一个好的开始……这只是将fab更改为brands

的示例

//find the index of object from array
const objIndex = objects.findIndex(obj => obj.value === 'fab');

// make new object of updated object   
const updatedObj = { ...objects[objIndex], prefix: 'brands'};

// make new array of objects
const updatedObjects = [
  ...objects.slice(0, objIndex),
  updatedObj,
  ...objects.slice(objIndex + 1),
];

Answer 1

编辑：添加了将驼峰式大小写转换为破折号

如果在发布时总是将对象切开，您是否可以做类似的事情？

const convertStrings = (str) => {
  return str.replace(/([A-Z])/g, (g) => `-${g[0].toLowerCase()}`);
};

const objects = {
  "brands": Object.keys(fab).map(convertStrings),
  "regular": Object.keys(far).map(convertStrings),
  "solid": Object.keys(fas).map(convertStrings),
}

哪个给了我输出：

{
  brands: ["facebook", "twitter", "instagram"],
  regular: ["arrow-up", "arrow-left", "arrow-right"],
  solid: ["carrot", "cat", "dog"]
}

您可以使用Object.keys获取键名，然后映射值，并返回obj[k].iconName：
