在具有字符串键的数组中对对象进行排序

Question

我有这个对象数组，我需要按照得分的降序对“列表”和“得分”进行排序。

var list =[{ '440684023463804938': { score: 6, bonuscount: 2 },
  '533932209300832266': { score: 20, bonuscount: 0 },
  '448746017987231756': { score: 9, bonuscount: 0 },
  '492585498561216513': { score: 14, bonuscount: 0 } }]

我通常使用.sort函数，但这一次它给了我list.sort不是一个函数

感谢您的帮助。

Answer 1

您可以将对象转换为数组，然后进行常规排序：

const list = [
    {
        '440684023463804938': {score: 6, bonuscount: 2},
        '533932209300832266': {score: 20, bonuscount: 0},
        '448746017987231756': {score: 9, bonuscount: 0},
        '492585498561216513': {score: 14, bonuscount: 0}
    }
];

const result = Object.entries(list[0]).sort((a, b) => b[1].score - a[1].score);

console.log(result);

如果要保留JSON体系结构，请从输入内容开始：

const input = [{ '440684023463804938': { score: 6, bonuscount: 2 },
  '533932209300832266': { score: 20, bonuscount: 0 },
  '448746017987231756': { score: 9, bonuscount: 0 },
  '492585498561216513': { score: 14, bonuscount: 0 } }];
  

const output = Object.keys(input[0]).sort((a,b) => b-a)
      .reduce( (acc , curr) => { 
                acc[curr] = input[0][curr];
                return acc; 
                },
                {});

console.log([output]);
