Question

在我的代码中，我希望能够通过 a）选择某些用户的Player对象。与createPlayer("Test")创建用户，然后能够调用用户提供Game.Player.Test，这样我可以做的事情，如记录他们的名字与console.log(Game.Player.Test.Name)等

这是我到目前为止，我的问题是低于几乎所有findPlayer，这是返回undefined

 var User = 'iJava'; 
     var Players = []; 
     function Game(Object, Name) { 
      this.Type = Object 
      this.Name = Name; 
     } 
     function Player(Username) { 
      this.Name = Username    
      this.getInfo = new Game("Player", this.Name) 
      this.Type = this.getInfo.Type 
      this.Move = function() { console.log("Moved",this.Name) } 
     } 
     function createPlayer(Username) { 
      if ($.inArray(Username, Players) == -1) { 
       new Game.newPlayer(Username) 
       Players.push(Username); 
       console.log("Created user "+Username+"!"); 
      } 
      else { 
       console.log("The user "+Username+" already exists!"); 
      } 
     } 
     function findPlayer(Username) { 
      return Game.getPlayer.Username; 
     } 
     Game.getPlayer = Player; 
     Game.newPlayer = Player 
     Game.Player = function(name) { findPlayer(name) }; 
     createPlayer(User);

你可以使用这样的东西。

var Game = {Players: []}; 

Game.Player = function Player (name) { 
    if (this.constructor[name]) 
     throw new Error("A player with this name already exists"); 

    // Store player on constructor for fast access, as well as in 
    // Game.Players array to easily iterate over all players. 
    Game.Players.push(this.constructor[name] = this); 
    this.Name = name; 
} 
// Use prototype to define object methods only once 
Game.Player.prototype.Move = function() { 
    console.log("Moving player: '" + this.Name + "'"); 
} 

new Game.Player("MyPlayer"); 
console.log(Game.Player.MyPlayer);
