javascript - 如何在Firechat中创建聊天室？

我正在使用Firechat，并且能够成功启动聊天窗口。我正在使用Firebase custom authentication，并且可以顺利登录。但是，我现在尝试创建一个新的聊天室，然后输入它。基于Firechat documentation，我执行了以下操作：

<!doctype html>
<html>
<head>
<title>Test</title>
<meta charset="UTF-8" />
<script src='https://cdn.firebase.com/js/client/2.0.2/firebase.js'></script>
<link rel='stylesheet' href='https://cdn.firebase.com/libs/firechat/2.0.1/firechat.min.css' />
<script src='https://cdn.firebase.com/libs/firechat/2.0.1/firechat.min.js'></script>
</head>
<body>

    <script type='text/javascript'>
    var fireBase = new Firebase("https://XXXXXXXXX.firebaseio.com/");

    function initChat(authData) {
      var Firechat = new FirechatUI(fireBase, document.getElementById('firechat'));
      Firechat.setUser(authData.uid, "Username");
      Firechat.createRoom("Test chat room", "public");
    }

    fireBase.authWithCustomToken("UNIQUE_TOKEN", function(error, authData) {
      if (error) {
        console.log("Login Failed!", error);
      } else {
        console.log("Login successful", authData);
        initChat(authData);
      }
    });
    </script>
    <div id='firechat'>
    </div>

</body>
</html>

在javascript控制台中，我可以看到登录成功：

Login successful Object { auth: Object, expires: XXXXXXXXX, token: "XXXXXXXX…", uid: "XXXXXX", provider: "custom" }

但是找不到createRoom函数：

TypeError: Firechat.createRoom is not a function

知道这里出了什么问题吗？

最佳答案

从文档：
Firechat.createRoom(roomName, roomType, callback(roomId))

创建具有给定名称（字符串）和类型（字符串-公共或私有）的新房间，并在完成时调用带有房间ID的回调。

似乎您没有回调。

 Firechat.prototype.createRoom = function(roomName, roomType, callback) {
    var self = this,
        newRoomRef = this._roomRef.push();

    var newRoom = {
      id: newRoomRef.name(),
      name: roomName,
      type: roomType || 'public',
      createdByUserId: this._userId,
      createdAt: Firebase.ServerValue.TIMESTAMP
    };

    if (roomType === 'private') {
      newRoom.authorizedUsers = {};
      newRoom.authorizedUsers[this._userId] = true;
    }

    newRoomRef.set(newRoom, function(error) {
      if (!error) {
        self.enterRoom(newRoomRef.name());
      }
      if (callback) {
        callback(newRoomRef.name());
      }
    });
  };
