将对象的数组组合到JavaScript中的一个对象

Question

let myCurrentData = [
  {
    _id: "D01",
    name: "Lunetts",
    profession: "shop",
  },
  {
    _id: "D02",
    name: "Glasses",
    profession: "keeper",
  },
  {
    _id: "D03",
    name: "Auros",
    profession: "UiiSii",
  },
];

上面是我的mycurrentdata，我想将此数组转换为最终对象如下

 let myFinalData = {
 D01: "Lunetts",
  D02: "Glasses",
  D03: "Auros"
}

我只想使用_id和名称的值

Answer 1

const myCurrentData = [
  {
    _id: "D01",
    name: "Lunetts",
    profession: "shop",
  },
  {
    _id: "D02",
    name: "Glasses",
    profession: "keeper",
  },
  {
    _id: "D03",
    name: "Auros",
    profession: "UiiSii",
  },
];

const finalObject = myCurrentData
  .map((eachObject) => {
    const { profession, name, _id } = eachObject;
    return {
      [_id]: name,
    };
  })
  .reduce((prev, current) => {
    return {
      ...prev,
      ...current,
    };
  }, {});

console.log("finalObject is", finalObject);

希望它有效！

Answer 2

const data=[{_id:"D01",name:"Lunetts",profession:"shop"},{_id:"D02",name:"Glasses",profession:"keeper"},{_id:"D03",name:"Auros",profession:"UiiSii"}];

const out = {};

for (const obj of data) {
  out[obj._id] = obj.name;
}

console.log(out);

Answer 3

您可以使用降低并从中返回对象来实现此目的：

const myObj=  myCurrentData.reduce((acc,curr)=> {
    return {...acc, [curr._id]:curr.name}
  
}, {})

Answer 4

您可以使用对象的优势。进入方法与foreach循环相结合以获取属性名称和值并将其添加到先前声明的myFinalData对象中。像这样的东西可能是您想要的。希望它有帮助，芽。

const myCurrentData = [
  {
    _id: "D01",
    name: "Lunetts",
    profession: "shop",
  },
  {
    _id: "D02",
    name: "Glasses",
    profession: "keeper",
  },
  {
    _id: "D03",
    name: "Auros",
    profession: "UiiSii",
  },
];


 const myFinalData = {}
Object.entries(myCurrentData).forEach(([k,v]) => { myFinalData[v['_id']] = v['name']})

console.log(myFinalData);
