Javascript - 以自定义方式对字符串数组进行排序

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。我想对该数组进行排序，使其如下所示:守门员、后卫、中后卫、中场、边锋、前锋。我正在考虑枚举，但我不知道如何在这种情况下使用它们。

Answer 1

您可以将一个对象作为排序顺序，然后根据差异进行排序。

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);
