Javascript 对象获取值问题

Question

Photon Javascript SDK 上有 class 个 Actor。

var Actor = (function() {
  function Actor(name, actorNr, isLocal) { //constructor
    this.name = name;
    this.actorNr = actorNr;
    this.isLocal = isLocal;
    this.customProperties = {};
    this.suspended = false;
  }
  ...
}

它有属性 customProperties(Object)。当我尝试获取整个对象时，它起作用了：

console.log(actor.customProperties)

customProperties: {
  255: ""
  active_bonus: "0"
  avatar: "https://pp.userapi.com/c840731/v840731367/24f5a/FMmqz25jPeg.jpg"
  balance1: 8651830
  balance2: 10
  bonuses: {}
  exp: 1792250
  flag: ""
  id: 4
  rank: 0
  register_date: "3/11/2016"
  relations: (4)[-1, -1, -1, -1]
  score: 0
  state: "join"
  stats: {
    last_games: Array(5),
    games: 253,
    rank: 0,
    register_date: "3/11/2016",
    wins: 131
  }
  username: "player"
  __proto__: Object
}

当我尝试从此对象中获取特定值我在任何情况下都未定义案例.

console.log(actor.customProperties["avatar"])
console.log(actor.customProperties.avatar)
console.log(actor.customProperties[4])

所有这些方法return 未定义。请问关于这个问题有什么想法吗？

Answer 1

我注意到

中行的末尾没有逗号

console.log(actor.customProperties)

输出。您确定 customProperties 是有效的 JS 对象而不是字符串吗？

Answer 2

我只需要设置超时。 Actor 属性未初始化。问题已解决。
