javascript - 如何将对象更改为数组

Question

我有一个对象需要更改为数组。什么是最好的方法？

var x = {
    vehicle: {
      manufacturer: "Volkswagen",
      carlineName: "Golf",
    }
}

我想要下面的结果

var x = {
  vehicle: [
    {
      manufacturer: "Volkswagen",
      carlineName: "Golf",
    }
  ]
}

Answer 1

对于这个例子，你可以这样写:

var x = {
    vehicle: {
      manufacturer: "Volkswagen",
      carlineName: "Golf",
    }
}

x.vehicle = [x.vehicle]

console.log(x)

x.vehicle 获取

{
  manufacturer: "Volkswagen",
  carlineName: "Golf",
}

和方括号[x.vehicle]将该值放入一个数组中:

[{
  manufacturer: "Volkswagen",
  carlineName: "Golf",
}]

我们想用这个新值重新分配 x.vehicle，所以我们使用 x.vehicle = [x.vehicle]
