javascript - 将对象的特定属性转换为对象数组

Question

这是我原来的对象:

Data = {
  aesthetic: {
    heritage: 'aesthetic',
    description: 'sdokjosk',
    value: 5
  },
  architectural: {
    heritage: 'architectural',
    description: 'doodsjdj',
    value: 1
  },
  historical: {
    heritage: 'historical',
    description: 'dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ',
    value: 4
  },
  score: 3
};

我想编写一个函数来遍历对象并将仅包含“继承”、“描述”和“值”的属性转换为如下所示的数组:

 [{
    "heritage": "aesthetic",
    "description": "sdokjosk",
    "value": 5
 },
  {
    "heritage": "architectural",
    "description": "doodsjdj",
    "value": 1
  },
  {
    "heritage": "historical",
    "description": "dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ",
    "value": 4
  }
]

这是我尝试过的:

Object.values(数据)但这会返回一个数组，末尾带有来自 Score 属性的 3

Answer 1

您可以使用Object.values() method 获取值的数组，然后使用 Array#filter() method 仅过滤其中的对象。

这就是您的代码:

var result = Object.values(Data).filter(x => typeof x == 'object');

演示:

这是一个有效的演示片段:

var Data = {
  aesthetic: {
    heritage: 'aesthetic',
    description: 'sdokjosk',
    value: 5
  },
  architectural: {
    heritage: 'architectural',
    description: 'doodsjdj',
    value: 1
  },
  historical: {
    heritage: 'historical',
    description: 'dcnsdlnckdjsncksdjbk kjdsbcjisdc hsdk chjsd cjhds ',
    value: 4
  },
  score: 3
};

var result = Object.values(Data).filter(x => typeof x == 'object');
console.log(result);
