Question

我具有以下结构的JavaScript对象数组：

var arrayObj = [
  {

    "Rank": 1,
    "Title": "The Shawshank Redemption",
    "Description": "Two imprisoned men bond over a number of years, finding solace and eventual redemption through acts of common decency.",
    "Runtime": 142,
    "Genre": "Crime",
    "Rating": 9.3,
    "Metascore": 80,
    "Votes": 1934970,
    "Gross_Earning_in_Mil": 28.34,
    "Director": "Frank Darabont",
    "Actor": "Tim Robbins",
    "Year": 1994
  },

  {

    "Rank": 2,
    "Title": "The Godfather",
    "Description": "The aging patriarch of an organized crime dynasty transfers control of his clandestine empire to his reluctant son.",
    "Runtime": 175,
    "Genre": "Crime",
    "Rating": 9.2,
    "Metascore": 100,
    "Votes": 1323670,
    "Gross_Earning_in_Mil": 134.97,
    "Director": "Francis Ford Coppola",
    "Actor": "Marlon Brando",
    "Year": 1972
  }]

我想从除“导演”之外的每个对象中提取一个字段，并获取一个包含值的数组，例如

[[1,
    'The Shawshank Redemption',
    'Two imprisoned men bond over a number of years, finding solace and 
     eventual redemption through acts of common decency.',
    142,
    'Crime',
    9.3,
    80,
    1934970,
    28.34,
    'Tim Robbins',
    1994 ],

[ 2,
    'The Godfather',
    'The aging patriarch of an organized crime dynasty transfers control 
     of his clandestine empire to his reluctant son.',
    175,
    'Crime',
    9.2,
    100,
    1323670,
    134.97,
    'Marlon Brando',
    1972 ]]

Answer 1

您可以通过分解并使用其余属性来排除键。

var array = [{ Rank: 1, Title: "The Shawshank Redemption", Description: "Two imprisoned men bond over a number of years, finding solace and eventual redemption through acts of common decency.", Runtime: 142, Genre: "Crime", Rating: 9.3, Metascore: 80, Votes: 1934970, Gross_Earning_in_Mil: 28.34, Director: "Frank Darabont", Actor: "Tim Robbins", Year: 1994 }, { Rank: 2, Title: "The Godfather", Description: "The aging patriarch of an organized crime dynasty transfers control of his clandestine empire to his reluctant son.", Runtime: 175, Genre: "Crime", Rating: 9.2, Metascore: 100, Votes: 1323670, Gross_Earning_in_Mil: 134.97, Director: "Francis Ford Coppola", Actor: "Marlon Brando", Year: 1972 }],
    result = array.map(({ Director, ...o }) => o);

console.log(result);

从对象数组中，仅提取属性的特定值作为数组
