javascript - 通过具有不同键的对象数组进行映射

Question

我有以下数组

const myArrayOfPurchasedCars = [{
    honda: {
      user: 'et',
      links: {
        img: {
          href: 'some0imghere'
        },
        year: 2010
      },
      {
        camry: {
          user: 'st',
          links: {
            img: {
              href: 'some0imghere'
            },
            year: 2014
          },
          {
            maxima: {
              user: 'lt',
              links: {
                img: {
                  href: 'some0imghere'
                },
                year: 2015
              },
              {
                optima: {
                  user: 'it',
                  links: {
                    img: {
                      href: 'some0imghere'
                    },
                    year: 2018
                  }
                ]

并且我希望能够访问用户而不必说 myarray[0].honda || myArray[1].camry。

有没有办法用 map 函数来做到这一点？

Answer 1

您可以使用map和Object.values。

myArrayOfPurchasedCars.map(function (car) { return Object.values(car)[0].user; });
