如何使用 javascript 更改一个对象中的键?

2022-01-19 00:00:00 arrays object frontend javascript typescript

我有:

    var myAbc = { 0: true, 1: false, 2: true };

我想更改 de 键，例如:

and i want to change de keys like: 

var myAbc = { key1: true, key2: false, key3: true };

我已经试过了:

 for (var key in array) {
            key = value;
        }

但是没有改变数组的键位在for的外面，有什么帮助吗?

but did not change the key of the array out side of the for, any help?

推荐答案

如果你会用es6，你可以一行行搞定:

If you can use es6, you can do this in one line:

var myAbc = { 0: true, 1: false, 2: true };

var renamed = Object.keys(myAbc).reduce((p, c) => { p[`key${Number(c)+1}`] = myAbc[c]; return p; }, {})

console.log(renamed)
