javascript - 在lodash中将对象数组转换为单个对象数组

我有一个对象数组的数组，如下所示，它是由_.filter lodash函数生成的，该函数返回对象作为匹配值:

const matchedPositions = _.filter(allPositions, function(o) {
return o.company.toLowerCase() === value.toLowerCase();
});//matchedPositions have array of objects
let allCheckboxFiltered = [...allCheckboxFiltered, matchedPositions]; //allCheckboxFiltered  have below results

   [
    [{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
    {serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}],
    [{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
    {serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
    {serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}]
    ];

我想要以下预期结果；

[
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}
];

我尝试了reduce函数来生成如下所示的预期结果:

let result = temp1.reduce(function(res, obj) {
console.log(res, obj);
Object.keys(obj).forEach(function(k) {
res[k] = res[k] || [];
res[k] = res[k].concat(obj[k]);
});
return res;
}, []);

我想要上面的代码无法生成结果。我尝试了其他东西，例如lodash也可以起作用，但都是徒劳的。

谢谢

最佳答案

您可以如下使用reduce:

var temp1 = [
[{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}],
[{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}]
];

var result= temp1.reduce((o, m) => m.concat(o), []);
console.log(result);

如果您想使用更多ES6功能:

var temp1 = [
[{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}],
[{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"},
{serialNo: 9, sector: null, company: "AMERICAN LIFE INSURANCE COMPANY", location: null, position: "INSURANCE Operations  MANAGER"}]
];

var result= temp1.reduce((o, m) => [...m, ...o], []);
console.log(result);
