javascript - 如何根据Javascript中的嵌套值过滤数组

Question

我有一个数组，我试图根据某个嵌套值进行过滤，而不获取任何其他元素。

const arrayData = [ 
{ 
    country: "Country X", 
    games: [ 
        { 
            gameTitle: 'Game1', 
            players: [{ name: 'John', status:'Active' },{ name: 'Rob', status:'Suspended' }] 
        }, 
        { 
            gameTitle: 'Game2', 
            players: [{ name: 'Saly', status:'Blocked' }] 
        }, 
    ] 
}, 
{ 
    country: "Country Y", 
    games: [ 
        { 
            gameTitle: 'Game1', 
            players: [{ name: 'Sindy', status:'Pending' },{ name: 'someone', status:'Rejected' }] 
        }, 
        { 
            gameTitle: 'Game2', 
            players: [{ name: 'Alex', status:'New' },{ name: 'Nic', status:'Old' }] 
        }, 
    ] 
}, 
]; 

我尝试过的:

let output = arrayData.filter(eachVal => { 
let opt = eachVal.games.some(( 
    { players }) => players 
    .some(({ status}) => status === 'Active')); 
return opt; 
}) 

查找具有 status 值的 所有玩家 的预期结果:'Active':

{ 
country: "Country X", 
games: [ 
    { 
        gameTitle: 'Game1', 
        players: [{ name: 'John', status:'Active' }] 
    }
] 
}

但是结果:

[{"country":"Country X","games":[{"gameTitle":"Game1","players":[{"name":"John","status":"Active"},{"name":"Rob","status":"Suspended"}]},{"gameTitle":"Game2","players":[{"name":"Saly","status":"Blocked"}]}]}]

试试这个:

arrayData.map(({country, games: g}) => {
  
  const games = g.map((g) => { 
    const players = g.players.filter((p) => p.status === 'Active')
  
    return {...g, players}
  })
  .filter(({players}) => players.length > 0)
  
  return {country, games}
}).filter(({games}) => games.length>0)
