Question

我有初始数组，应该对其进行迭代并应该创建新对象。初始数组为：

let array = [
    {key: "key1", translation: "some text 1"},
    {key2: "key2", translation: "some text 2"},
    {key3: "key3", translation: "some text 3"},
];

然后我对其进行迭代并创建对象：

const final = {};
const language = "eng";

for (let item of array) {
    final[item.key] = {};
    final[item.key][language] = item.translation;
}

它最终成为对象：

{
  key1: {
    eng: "Some text 1"
  },
  key2: {
    eng: "Some text 2"
  },
  key3: {
    eng: "Some text 3"
  }
}

我需要将这些外键（key1，key2和key3）用双引号引起来，以便最终对象变为：

{
  "key1": {
    eng: "Some text 1"
  },
  "key2": {
    eng: "Some text 2"
  },
  "key3": {
    eng: "Some text 3"
  }
}

Answer 1

我认为您正在寻找JSON.stringify()。让我们在这里看看：

let array = [
{key: "key1", translation: "some text 1"},
{key2: "key2", translation: "some text 2"},
{key3: "key3", translation: "some text 3"},
];
console.log(JSON.stringify(array));

Answer 2

如果您使用JSON.stringify()来获取数组的JSON字符串，则该值会被完美引用：

let array = {
  key1: {
    eng: "Some text 1"
  },
  key2: {
    eng: "Some text 2"
  },
  key3: {
    eng: "Some text 3"
  }
};

console.log(JSON.stringify(array));

Answer 3

您编写的循环不正确。应该是这样的：

let array = [
{key: "key1", translation: "some text 1"},
{key2: "key2", translation: "some text 2"},
{key3: "key3", translation: "some text 3"},
];

const final = {};
const language = "eng";

for (let item of array) {
    final[Object.values(item)[0]] = {};
    final[Object.values(item)[0]][language] = item.translation;
}

console.log(JSON.stringify(final));

此外，不要忘记使用JSON.stringify()进行字符串化。

let array = [
    {key: "key1", translation: "some text 1"},
    {key: "key2", translation: "some text 2"},
    {key: "key3", translation: "some text 3"},
];

    let data={};
    array.map(item => {
        let d=item.key;
        let da=item.translation;
        data[d]=da;
    })
}

console.log(data)

Javascript-创建对象，其中键用双引号引起来
