Javascript 阵列图&；reduce显示未定义的值

我有两个名为

headersMap

和

selected\u arr

的数组，如下所示

headersMap: [
    {
      text: "#",
      align: "center",
      sortable: true,
      value: "id",
      align: "start",
      width: "1%",
    },
    {
      text: "Name",
      align: "center",
      sortable: true,
      value: "name",
      align: "start",
    },
    {
      text: "Company",
      align: "center",
      sortable: true,
      value: "company",
      align: "start",
    }
 ]

我的尝试如下：

let jsonObject = this.headersMap;
let selectedArray = this.selected_arr;
let filteredJsonObject = jsonObject.map(function(entry) {
    return selectedArray.reduce(function(res, key) {
        res[key] = entry[key];
        return res;
    }, {});
});

console.log(filteredJsonObject);

[
    {
      text: "#",
      align: "center",
      sortable: true,
      value: "id",
      align: "start",
      width: "1%",
    },
    {
      text: "Company",
      align: "center",
      sortable: true,
      value: "company",
      align: "start",
    }
 ]

输出：

[
    {
      #: undefined
      company: undefined
    }
]

问题：我想通过

selected\u arr

减少

headersMap

，输出应如下所示：

let jsonObject = this.headersMap;
let selectedArray = this.selected_arr;
let filteredJsonObject = jsonObject.map(function(entry) {
    return selectedArray.reduce(function(res, key) {
        res[key] = entry[key];
        return res;
    }, {});
});

console.log(filteredJsonObject);

[
    {
      text: "#",
      align: "center",
      sortable: true,
      value: "id",
      align: "start",
      width: "1%",
    },
    {
      text: "Company",
      align: "center",
      sortable: true,
      value: "company",
      align: "start",
    }
 ]

使用：

const
headersMap=[
{text:#，align:“center”，sortable:true，value:“id”，align:“start”，width:“1%”，
{text:“Name”，align:“center”，sortable:true，value:“Name”，align:“start”}，
{text:“Company”，align:“center”，sortable:true，value:“Company”，align:“start”}
],
选定的_arr=['id'，'company']；
const filtered=headersMap.filter（（{value}）=>selected_arr.includes（value））；
console.log（过滤）
