如何将Javascipt数组转换为对象？

Question

我在Javascript中有一个数组数组，例如

[
    ["2019","abc","xyz"],
    ["2014","DEF","PQR"]
]

如何将上述数组转换为对象数组，如

[
    {
        date: 2019,
        name:abc,
        address:xyz
    },
    {
        date: 2014,
        name: DEF,
        address: PQR
    }
]

Answer 1

您可以使用Array.map

let arr = [["2019","abc","xyz"],["2014","DEF","PQR"]];
let result = arr.map(([data,name,address]) => ({data, name, address}));
console.log(result);

Answer 2

您可以使用Array.map建立所需的格式，这里我是date, name, and address中每个数组的Destructuring元素，而不是返回带有这些key/value对的对象

let data =  [["2019","abc","xyz"],["2014","DEF","PQR"]]

let op = data.map(([date, name, address]) => ({date, name, address}))

console.log(op)

Answer 3

一个简单的例程

var arr = [["2019","abc","xyz"],["2014","DEF","PQR"]];

var output = [];

arr.forEach(function(el){

    output.push({
        date: el[0],
        name: el[1],
        address: el[2]
    });
});

console.log(output)
