Question

我有一个对象数组：

[  
   {  
      "Accept Credit Cards":"17",
      "Take-Out":"17",
      "Alcohol":"16",
      "Caters":"10",
      "Takes Reservations":"11",
      "Smoking":"0",
      "Dogs Allowed":"1",
      "Outdoor Seating":"12",
      "Coat Check":"0",
      "Waiter Service":"14",
      "Wi-Fi":"10",
      "Good For Groups":"16",
      "Wheelchair Accessible":"13"
   }
]

我想根据价值对此进行排序。所以我的结果应该是这样的：

[  
       {  
          "Accept Credit Cards":"17",
          "Take-Out":"17",
          "Alcohol":"16",
          "Good For Groups":"16",
          "Wheelchair Accessible":"13"
          AND SO ON.....

      }
]

我将如何做到这一点？我试了一下。但这只是基于密钥进行排序。任何指针都赞赏。

正如RyanZim在评论中提到的那样，排序对象的属性并不是真正的目的。 JavaScript不保证属性顺序，因此您不应该依赖它们。但是，您可以创建一个属性数组，并根据对象中的值对它们进行排序。

＆＃13;

const arr = [  
   {  
      "Accept Credit Cards":"17",
      "Take-Out":"17",
      "Alcohol":"16",
      "Caters":"10",
      "Takes Reservations":"11",
      "Smoking":"0",
      "Dogs Allowed":"1",
      "Outdoor Seating":"12",
      "Coat Check":"0",
      "Waiter Service":"14",
      "Wi-Fi":"10",
      "Good For Groups":"16",
      "Wheelchair Accessible":"13"
   }
];

const sorted = Object.keys(arr[0]).sort((a, b) => arr[0][b] - arr[0][a]);

sorted.forEach(x => console.log(x + ': ' + arr[0][x]));

＆＃13;

如果你想变得更加漂亮并按字母顺序排序：

＆＃13;

const arr = [  
   {  
      "Accept Credit Cards":"17",
      "Take-Out":"17",
      "Alcohol":"16",
      "Caters":"10",
      "Takes Reservations":"11",
      "Smoking":"0",
      "Dogs Allowed":"1",
      "Outdoor Seating":"12",
      "Coat Check":"0",
      "Waiter Service":"14",
      "Wi-Fi":"10",
      "Good For Groups":"16",
      "Wheelchair Accessible":"13"
   }
];

const sorted = Object.keys(arr[0]).sort((a, b) => {
  if (arr[0][a] > arr[0][b]) return -1;
  if (arr[0][a] < arr[0][b]) return 1;
  if (a > b) return 1;
  if (a < b) return -1;
  return 0;
});

sorted.forEach(x => console.log(x + ': ' + arr[0][x]));
