在 Javascript 中组合两个数组以创建 JSON [重复]

Question

我有两个数组：

headers=['medium','source', 'name']

rows=[
['direct', 'google', 'demoAccount'],
['direct', 'google', 'demoAccount'],
['direct', 'google', 'demoAccount']
]

我怎样才能将它们结合起来并创建一个带有数据的 JSON 来保存以下内容：

   {
 {medium:direct, 
    source:google,
    name:demoAccount},
    {medium:direct, 
    source:google,
    name:demoAccount},{medium:direct, 
    source:google,
    name:demoAccount}
}

Answer 1

您可以使用array#map 和array#reduce

const headers=['medium','source', 'name'];

const rows=[['direct', 'google', 'demoAccount'],['direct', 'google', 'demoAccount'],['direct', 'google', 'demoAccount']];

var result = rows.map((arr) => {
  return arr.reduce((o, n, i) => {
    o[headers[i]] = n;
    return o;
  }, Object.create(null));
});

console.log(result);
