将给定字符串与数组子属性进行比较

Question

我正在构建一个 players 数组，当在 players 内的 name 属性中找不到 solver 时，将添加该数组

let players = []

let solver = 'Any Name Given'

// This if statement is the issue : How to check the name properties and compare to solver 
// If the solver's name is already in players : add +1 point
if(players.includes(solver)){

   // Give The Player +1 point

   return console.log('Player Exists')

 } else {

   // Add The newPlayer to players with a starting point 
   let newPlayer = [name = solver, points = 1]
   players.push(newPlayer)

}

如何比较 solver 内的 name 和 players。我试过 players[name] 和 players.name 没有运气

Answer 1

在您的else 中，您应该拥有：

const newPlayer = {name: solver, points: 1};

即一个对象，而不是一个数组。这样你就有了 players 数组，它总是有 player 对象

现在，由于您拥有的是一个对象数组，因此您需要使用 some 之类的东西来查找是否存在符合您条件的对象：

if 条件可以替换为：

if (players.some(player => player.name === solver))

我刚刚看到你想将找到的玩家的积分增加1。在这种情况下，您应该使用find 而不是some，以便您可以访问找到的播放器并更新其points 属性。这样做：

const player = players.find(player => player.name === solver);

if (player) {
    player.points++;
} else {
    const newPlayer = {name: solver, points: 1};
    players.push(newPlayer)
}
