Javascript TypeError:this.io是未定义的socket.io.js:639

我尝试从JavaScript连接到nodejs套接字服务器（用于在phonegap-PhoneRTC插件中使用webrtc）

我有server.js代码：

var app = require('express')();
var server = require('http').createServer(app);

var webRTC = require('webrtc.io').listen(server);
var io = require('socket.io')(server);
var port = process.env.PORT || 1234;
server.listen(port);




app.get('/', function(req, res) {
  res.sendfile(__dirname + '/index.html');
});

app.get('/style.css', function(req, res) {
  res.sendfile(__dirname + '/style.css');
});

app.get('/fullscrean.png', function(req, res) {
  res.sendfile(__dirname + '/fullscrean.png');
});

app.get('/script.js', function(req, res) {
  res.sendfile(__dirname + '/script.js');
});

app.get('/webrtc.io.js', function(req, res) {
  res.sendfile(__dirname + '/webrtc.io.js');
});





webRTC.rtc.on('chat_msg', function(data, socket) {
  var roomList = webRTC.rtc.rooms[data.room] || [];

  for (var i = 0; i < roomList.length; i++) {
    var socketId = roomList[i];

    if (socketId !== socket.id) {
      var soc = webRTC.rtc.getSocket(socketId);

      if (soc) {
        soc.send(JSON.stringify({
          "eventName": "receive_chat_msg",
          "data": {
            "messages": data.messages,
            "color": data.color
          }
        }), function(error) {
          if (error) {
            console.log(error);
          }
        });
      }
    }
  }
});

如果有人遇到过类似的问题-帮助。我将非常感谢你的建议

我想是使用1.1.0版吧

更改套接字对象的创建

var socket = io.connect('http://my-saite:1234');

那么剩下的就不成问题了

// Add a connect listener
socket.on('connect',function() {
  alert ('Client has connected to the server!');
});
// Add a connect listener
socket.on('message',function(data) {
  alert ('Received a message from the server!',data);
});
// Add a disconnect listener
socket.on('disconnect',function() {
  alert ('The client has disconnected!');
});

// Sends a message to the server via sockets
function sendMessageToServer(message) {
  socket.send(message);
};

您使用的是什么版本的socket.io？您好。最新版本-1.1.0

var socket = io.connect('http://my-saite:1234');

// Add a connect listener
socket.on('connect',function() {
  alert ('Client has connected to the server!');
});
// Add a connect listener
socket.on('message',function(data) {
  alert ('Received a message from the server!',data);
});
// Add a disconnect listener
socket.on('disconnect',function() {
  alert ('The client has disconnected!');
});

// Sends a message to the server via sockets
function sendMessageToServer(message) {
  socket.send(message);
};
