javascript - 普通 JS 中的数组到 obj

Question

我有一个数组，需要通过组合键/值来从中创建一个对象。任何想法如何去 1. 递归和 2. 不递归-
使用纯 JS 编写，无需任何外部库(如下划线、Lodash 等)

[
    [
        ['firstName', 'Eren'], ['lastName', 'Duran'], ['age', 22], ['role', 'admin']
    ],
    [
        ['firstName', 'Sallito'], ['lastName', 'Jordan'], ['age', 16], ['role', 'server']
    ]
]

应该变成:

  [
        {firstName: 'Eren', lastName: 'Duran', age: 22, role: 'admin'},
        {firstName: 'Sallito', lastName: 'Jordan', age: 16, role: 'server'}
    ]

Answer 1

您可以使用 Array#map 的迭代方法和 Array#forEach .

var array = [[['firstName', 'Eren'], ['lastName', 'Duran'], ['age', 22], ['role', 'admin']], [['firstName', 'Sallito'], ['lastName', 'Jordan'], ['age', 16], ['role', 'server']]],
    result = array.map(function (a) {
        var object = {};
        a.forEach(function (b) {
            object[b[0]] = b[1];
        });
        return object;
    });

console.log(result);

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