javascript - 如何按照预定的层次结构对 JavaScript 数组进行排序

Question

假设我有这样的层次结构:

0 King
1 Queen
2 Tower
3 Bishop
4 Knight
5 Pawn

以及一个包含以下元素的数组:

array = [Tower, Pawn, Bishop, Queen]

如何按照层次结构对其进行排序？

array = [Queen, Tower, Bishop, Pawn]

Answer 1

创建一个定义层次结构的对象:

const hierarchyMap = {
  King: 0,
  Queen: 1,
  Tower: 2,
  Bishop: 3,
  Knight: 4,
  Pawn: 5,
}

然后根据层次结构值对数组进行排序:

array.sort((first, second) => hierarchyMap[first] - hierarchyMap[second]);

反之亦然:

array.sort((first, second) => hierarchyMap[second] - hierarchyMap[first]);

const hierarchyMap = {
  King: 0,
  Queen: 1,
  Tower: 2,
  Bishop: 3,
  Knight: 4,
  Pawn: 5,
}


let array = ["Tower", "Pawn", "Bishop", "Queen"];

let sorted = array.sort((first, second) => hierarchyMap[first] - hierarchyMap[second]);

console.log(sorted)
