如何按两个属性对 JSON 数据进行排序？下面的函数仅按Episode排序..

目标:按Episode升序排列，然后按Sequence升序排列

var data = [ { ArticleId: 2, Episode: 1, Type: 0, Sequence: 0 },
  { ArticleId: 1, Episode: 1, Type: 0, Sequence: 1 },
  { ArticleId: 3, Episode: 2, Type: 0, Sequence: 0 },
  { ArticleId: 4, Episode: 2, Type: 0, Sequence: 1 } ];

var data = [ { ArticleId: 2, Episode: 1, Type: 0, Sequence: 1 },
  { ArticleId: 1, Episode: 2, Type: 0, Sequence: 0 },
  { ArticleId: 3, Episode: 1, Type: 0, Sequence: 0 },
  { ArticleId: 4, Episode: 2, Type: 0, Sequence: 1 } ];


function compareEpisodeSequence(a,b) {
  if (a.Sequence < b.Sequence)
    return -1;
  if (a.Sequence > b.Sequence)
    return 1;
  return 0;
}
data.sort(compareEpisodeSequence);

console.log(data);

Answer 1

这应该做你想做的事:

function compareEpisodeSequence(a,b) {
  if (a.Episode < b.Episode) return -1;
  if (a.Episode > b.Episode) return 1;
  if (a.Sequence < b.Sequence) return -1;
  if (a.Sequence > b.Sequence) return 1;
  return 0;
}

如果剧集相等，则继续比较序列
