javascript - 在构造函数中使用循环创建多个对象

Question

尝试在构造函数的函数中创建多个对象时遇到问题。

我正在尝试创建多个对象，每个对象都有数组 hand，并且每个对象都有名称 player(x)，因此它将是 player0: [array],player1:[array]，但它不起作用。我收到错误

Cannot set property '0' of undefined

代码:

function Player () {
  this.hand = []
}

function Players () {

}

Players.prototype.createPlayers = function (x) {
    for (let i = 0; i < x; i++) {
      this.player[i] = new Player()
  }
}

let gamer = new Players()
console.log(gamer)

gamer.createPlayers(3)
console.log(gamer.players)

Answer 1

这是可行的尝试一下，这是你想要的吗？

function Player () {
  this.hand = []
}

function Players () {
  this.player = [];
}

Players.prototype.createPlayers = function (x) {
    for (let i = 0; i < x; i++) {
      this.player[i] = new Player()
  }
}

let gamer = new Players()
console.log(gamer)

gamer.createPlayers(3)
console.log(gamer.players)
