数字作为对象键，值作为数组

Question

该对象怎么了？

const ob= {
  "1": [
    {
      "name": "destination"
   }
  ]
}, {
  "2": [
    {
      "name": "destination"
    }
  ]
}

为什么我不能做ob['1']或ob['2']？对象的值不能包含数组？

Answer 1

您的对象结构不正确。您需要将1和2放在对象ob的同一级别上：

const ob = {
  "1": [{
    "name": "destination"
  }],

  "2": [{
    "name": "destination"
  }]
};
console.log(ob['1']);
console.log(ob['2']);

Answer 2

对象的结构无效。右括号弄乱了。

const ob = {
  "1": [{
    "name": "destination",

  }],
  "2": [{
    "name": "destination",

  }]
}

console.log(ob['1']);
console.log(ob['2']);
