高效数据转化

const data = {
    "id": [
        "b903dc447548319646f2eac7709e377c",
        "3540c7c8ba2c8e1f940165198d712a2c",
        "a2f12d6bc367a116e974bd7c761d036c",
        "dfd3cfd2044fb94f9974f12fc4928828"
    ],
    "name": [
        "1",
        "2",
        "3",
        "系统管理员"
    ],
    "role": [
        "user",
        "admin",
        "guest"
    ]
};

想要把上面的数据格式转化成普通的数组对象[{id:xxx,name:xxx,role:xxx}]格式

 

// 获取所有字段名
const keys = Object.keys(data);

// 获取数组的最大长度
const maxLength = Math.max(...keys.map(key => data[key].length));

// 构造结果数组
const result = Array.from({ length: maxLength }, (_, index) => {
    return keys.reduce((acc, key) => {
        acc[key] = data[key][index] || null; // 如果当前索引不存在，则填充 null
        return acc;
    }, {});
});

console.log(result);
