javascript - 将 3 个数组的数组转换为 1 个带有对象变量的大数组

Question

我是 StackOverflow 的新手，我知道这篇文章可能与另一篇文章重复，所以请不要对我投反对票，如果您认为我的问题有答案，请发布它，我将删除这个问题。感谢您的理解。

var array1 = ["name", "title", "desc"]
var array2 = [["name1", "name2"], ["title1", "title2"],["desc1", "desc2"]]

我如何将它们变成:

[
 {name: "name1", title: "title1", desc: "desc1"},
 {name: "name2", title: "title2", desc: "desc2"}
]

Answer 1

您可以使用Array#map , Object.assign (使用 spread syntax )和 ES6 computed property实现这一点的语法:

const array1 = ["name", "title", "desc"],
    array2 = [["name1", "name2"], ["title1", "title2"],["desc1", "desc2"]];

const result = array2[0].map( (_, j) =>
    Object.assign(...array1.map( (key, i) => ({ [key]: array2[i][j] }) ))
);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
