I'm working in a chatsystem using websockets. Soon I realised it didn't work well in IE11 and Edge. So I've started working on a seperate JS file for those browsers using ES2015 instead of ES2016. Unfortunetely IE11 keeps bugging me like crazy!

I'm getting an Object Expected error on Socket.onopen in the following code:

function Chat(){

    /* Settings */

    this.serverHost = window.location.host;

    this.serverPort = 9300;

    this.socket = false;

}



Chat.prototype.connect = function(){

    var Socket = new WebSocket('wss://'+this.serverHost+'/myws/');

    this.setSocketEvents(Socket);

    this.socket = Socket;

}



Chat.prototype.setSocketEvents = function(Socket){

    Socket.onopen(function() { // Object expected error

        // some code..

    });

}

Console log: Socket

{binaryType: "blob", bufferedAmount: 0, CLOSED: 3, CLOSING: 2, CONNECTING: 0, extensions: "", onclose: null, onerror: null, onmessage: null, onopen: null, OPEN: 1, protocol: "", readyState: 0, url: "wss://mywebsite..."}

Console log: typeof(Socket)

object

I'm pretty much lost here. Anyone able to tell me what's going on?
