Javascript - 按自定义方式排序字符串数组

Question

我有一个字符串数组：

var players = [{Name: player1name, Surname: player1surname, Position: "Centre back"}, {Name: player2name, Surname: player2surname, Position: "Striker"}, {Name: player3name, Surname: player3surname, Position: "Full back"}, {Name: player4name, Surname: player4surname, Position: "Goalkeeper"}, {Name: player5name, Surname: player5surname, Position: "Midfielder"}, {Name: player6name, Surname: player6surname, Position: "Winger"}];

数组项的顺序并不总是相同的。 我希望将该数组排序，使其按照以下顺序排列：守门员、后卫、中后卫、中场球员、边锋、前锋。 我考虑使用枚举，但不知道如何在这种情况下使用。

如果您知道所需的顺序，为什么不按照那个顺序定义数组呢？ - trincot

你想要订购哪种逻辑？ - Murad Sofiyev

@trincot 我做不到，因为我从数据库中获取特定小组的球员，而当我得到它们时球员并没有排序。每个球员都有一个“位置”属性。 - user7479651

如果您包括玩家的价值，那么这个问题会更有趣，因为现在（只有位置），看起来像是一个不存在的问题。 - trincot

@trincot 我编辑了一个问题。我会在下面尝试回答。如果你有更简单的解决方案，请随意建议。 - user7479651

Answer 1

您可以使用对象来确定排序顺序，然后按照差异进行排序。

var players = ["Centre back", "Striker", "Full back", "Goalkeeper", "Midfielder", "Winger"],
    order = { Goalkeeper: 1, 'Full back': 2, 'Centre back': 3, Midfielder: 4, Winger: 5, Striker: 6 };
    
players.sort(function (a, b) {
    return order[a] - order[b];
});

console.log(players);

如果他可以手动使用对象定义顺序，他就可以直接更改数组本身:D 不管怎样，很棒。点个赞。 - Suresh Atta

我认为这只是一个简化的数组，以便在对象中使用更多数据。 - Nina Scholz

是的。可以考虑那种情况。 - Suresh Atta

能否在具有“位置”属性的对象数组上使用该逻辑？ - user7479651

@user7479651，使用return order[a.position] - order[b.position];是可行的。 - Nina Scholz

谢谢，我会尝试的。顺便说一下，我已经编辑了一个问题，如果您可以编辑您的答案。 - user7479651

Answer 2

好的，你应该使用这种方法。 你需要创建一个排名映射，然后按照该映射进行排序。

players = players.sort((a, b) => rankMap[a.position] - rankMap[b.position]);

console.log(players);
