Question

我有一个看起来像这样的对象：

{
  "1": "Technology",
  "2": "Startup",
  "3": "IT",
}

我需要将它转换为一个看起来像这样的对象数组：

[
  {id: 1, name: "Technology"},
  {id: 2, name: "Startup"},
  {id: 3, name: "IT"}
]

什么是最干净的＆amp;有效的方法吗？

Answer 1

您可以将.map()与Object.keys()：

一起使用

＆＃13;

let data = {
    "1": "Technology",
    "2": "Startup",
    "3": "IT",
};

let result = Object.keys(data)
                   .map(key => ({id: Number(key), name: data[key]}));

console.log(result);

＆＃13;

Answer 2

假设您的对象实例名为obj：

Object.keys(obj).reduce((acc, curr) => {
    return [...acc, { id: curr, name: obj[curr] }]
}, [])

Answer 3

琐碎的方式

var o = {
    "1": "Technology",
    "2": "Startup",
    "3": "IT",
};
var arr = [];
for(var i in o) {
    arr.push({
        id: i,
        number: o[i]
    });
};

Answer 4

const words = {
  told: 64,
  mistake: 11,
  thought: 16,
  bad: 17
}

const results = []

Object.entries(words).map(val => results.push({
  text: val[0],
  value: val[1]
}))

console.log(results)

将对象转换为对象数组？
