有些玩家有不同的职位
我想按照他们的位置命令每个球员，所以所有守门员先到先得，然后是所有中后卫，依此类推。
我正在使用React和Redux。我在Reducer文件中完成了一些工作，但我认为代码过于臃肿，下面是一个例子：
function sortPlayersByPosition(data) {
let players = data.players;
let result = [];
result.push(players.filter(function(obj) {
return obj.position === 'Keeper';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Centre-Back';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Right-Back';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Left-Back';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Defensive Midfield';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Central Midfield';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Attacking Midfield';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Right Wing';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Left Wing';
}));
result.push(players.filter(function(obj) {
return obj.position === 'Centre-Forward';
}));
data.players = result;
return data
}
export const fetchTeamPlayersReducer = (state = [], action) => {
switch (action.type) {
case 'FETCH_TEAM_PLAYERS_SUCCESS':
var sortedPlayers = sortPlayersByPosition(action.payload);
return sortedPlayers;
default:
return state;
}
}

所以你可以看到我把我的位置分成了不同的数组。我不希望这个结果。如果我有一个包含对象的数组，我真的很喜欢它。就像原始格式一样。
欢迎任何帮助。
谢谢！

您可以先制作有序位置数组：
const ORDERS = [
'Keeper',
'Centre-Back',
...
]
这个ORDERS数组的初始数组的排序
players.sort((player1, player2) => {
return ORDERS.indexOf(player2.position) - ORDERS.indexOf(player1.position);
});
答案 1 :(得分：0)
您可以尝试：
a = module.myvar
b = module.myfunc(a)
输出：
const positions = [
'Keeper', 'Centre-Back', 'Right-Back', 'Left-Back', 'Defensive Midfield',
'Central Midfield', 'Attacking Midfield', 'Right Wing', 'Left Wing', 'Centre-Forward',
];
data.players.sort((a, b) => positions.indexOf(a.position) > positions.indexOf(b.position));
答案 2 :(得分：0)
您可以定义包含排序优先级的对象，并定义自定义排序功能，如下所示：
players = [

sortOrder = {

function sort(player1, player2) {
const player1Value = sortOrder[player1.position];
const player2Value = sortOrder[player2.position];
if(player1Value > player2Value) { return 1; }
else if (player1Value < player2Value) { return -1; }
else { return 0; }
}
console.log(players.sort(sort));
