Play Framework 2.3 and javascript websocket client library

Question

I have installed the new Play Framework 2.3 with Scala 2.11, and I will build an application with websocket.

The server with scala in quite simple code:

object TestWebSocket extends Controller {

  def mysocketservice = WebSocket.acceptWithActor[String, String] { request => out =>
    TestSocketActor.props(out)
  }
}

the route.conf is: GET /wsk/testwebsocket controllers.TestWebSocket.mysocketservice

now i need a Javascript code for connect my page with the scala code, what javascript library can I use? I have seen a socket.io, but seems work only with node.js server.

I know than I can use a WebSocket directly, but i will using a library like socket.io for the compatibility with the old browser.

Can someone help me? Thank you very much

try out this javascript. This is the standard way to do it on Chrome, Safari, Mozilla etc.

<script type="text/javascript">
    function WebSocketTest(){
        if ("WebSocket" in window){ 
        var ws = new WebSocket("@routes.controllers.TestWebSocket.mysocketservice().webSocketURL()");
        ws.onopen = function(){
            // Web Socket is connected, send data using send()
            console.log("connected");
            ws.send("Message to send");
        };

        ws.onmessage = function (evt){
            var received_msg = evt.data;
            console.log(evt.data);
        };

        ws.onclose = function(){
            // websocket is closed.
            alert("Connection is closed...");
        };
        }else{
            // The browser doesn't support WebSocket
            alert("WebSocket NOT supported by your Browser!");
        }
    }
WebSocketTest();
</script>

Let me know how it goes.
