如何从一维数组和静态字符串创建对象 [英] How to create an object from one dimensional array and static string

问题描述

我想要一个像

var obj = {
    "ABC" : { name: true, dob: true},
    "CDE" : { name: true, dob: true},
    "EFG" : { name: true, dob: true},
    "CBA" : { name: true, dob: true},
    "XYZ" : { name: true, dob: true},
}

目前我只有数组

currently I have only array of

var arr = ["ABC","CDE","EFG","CBA","XYZ"];

---

我尝试添加

---

I have tried adding this with

newArray.push({
    key: arr[i],
    name: true,
    dob: true
});

var newObj = {}

newObj[i] = newArray;

但我无法将此作为整个对象传递给我的代码。当我将其字符串化时，它返回

but I am not able to pass this as an whole object to my code. when I stringify this it returns

{
    '0':"[{
        key: "ABC",
        name: true,
        dob: true
    },{
        key: "CDE",
        name: true,
        dob: true
    }]"
}

推荐答案

您可以使用 Object.assign 来创建对象。使用扩展运算符和 map 重复数组。

You can use Object.assign to create an object. Use spread operator and map to reiterate the array.

var arr = ["ABC", "CDE", "EFG", "CBA", "XYZ"];

var obj = Object.assign(...arr.map(o => ({[o]: {name: true,dob: true}})));
console.log(obj);

另一种选择是使用 reduce 将数组转换为有效对象。

Another option is using reduce to convert the array into a valid object.

var arr = ["ABC", "CDE", "EFG", "CBA", "XYZ"];
var obj = arr.reduce((c, v) => Object.assign(c, {[v]: {name: true,dob: true}}), {});

console.log(obj);
