javascript - 如何根据两个属性对数组对象进行排序

Question

嗨，我有一个对象数组

cards = [
{ Asset: "2C.jpg",
  CardName: "2C",
  CardPlayed: 0,
  Playbell: 0,
  PlayerName: "player1",
  Rank: 2,
  Suit: "C"
},
{ Asset: "9S.jpg",
  CardName: "9S",
  CardPlayed: 0,
  Playbell: 0,
  PlayerName: "player2",
  Rank: 9,
  Suit: "S"
},
{ Asset: "6D.jpg",
  CardName: "6D",
  CardPlayed: 0,
  Playbell: 0,
  PlayerName: "player1",
  Rank: 6,
  Suit: "D"
}];

我需要根据 Suit 属性对这些对象进行排序，但仅限于 PlayerName 属性值等于 "player1" 的对象> 非常感谢您的帮助。

Answer 1

要先按 PlayerName 对数组排序，然后按 Suit 排序:

cards.sort(function(x, y){
  return (
    x.PlayerName < y.PlayerName ? -1 :
    x.PlayerName > y.PlayerName ? 1 :
    x.Suit < y.Suit ? -1 :
    x.Suit > y.Suit ? 1 :
    0
  );
});
