I have the following code in javascript:
function ConnectWebSocket() {
if ("WebSocket" in window) {
myWebsocket = new WebSocket("wss://myserver/mychannel");
myWebsocket.onmessage = function(evt) {
alert("onmessage");
}
myWebsocket.onopen = function() {
alert("onopen");
myWebsocket.send("msg0");
myWebsocket.send("msg1");
myWebsocket.send("msg2");
}
myWebsocket.onclose = function() {
alert("onclose");
ConnectWebSocket();
}
} else {
// Do something if there is no websockets support
}
}
ConnectWebSocket();
The problem is that in Firefox, the connection is closed after sending the messages, and reopened due to the mand on the onclose event. If I try to send only one message on onopen, the connection keeps opened, but if I try to send more than one message, the connection shut down. This issue appears only in Firefox, not in Chrome, not in IE, not in Safari.
Can someone help me? In other browsers like IE or Chrome, once the connection is created, it keep opened until I leave the page. I have the 40.0.3v of Firefox

- Hello kakajan, this link is good for me, but it is a custom action. I need that it could be setted by code. Is it possible?Could you help me? THank you. – Manel Commented Sep 28, 2015 at 14:18
- The WebSockets API (and the underlying protocol) are still in active development, and there are many patibility issues across browsers at this time (and even among different releases of the same browser). I get this from mozilla's website Check the link, there is some WebSocket examples – kakajan Commented Sep 28, 2015 at 16:15
- And in which language did you write the server side of websocket? Java? – kakajan Commented Sep 28, 2015 at 16:16
-
Can you try sending messages outside of
.onopenfunction? I am not sure, but I think the problem occurs when you send messages in.onopenfunction. Same issue on this question too – kakajan Commented Sep 28, 2015 at 16:22

Reset to default 3Try this example:
var url = "ws://echo.websocket";
if (!window.WebSocket) alert("WebSocket not supported by this browser");
var myWebSocket = {
connect: function () {
var location = url
this._ws = new WebSocket(location);
this._ws.onopen = this._onopen;
this._ws.onmessage = this._onmessage;
this._ws.onclose = this._onclose;
this._ws.onerror = this._onerror;
},
_onopen: function () {
console.debug("WebSocket Connected");
},
_onmessage: function (message) {
console.debug("Message Recieved: " + message.data);
},
_onclose: function () {
console.debug("WebSocket Closed");
kiosk.connect();
},
_onerror: function (e) {
console.debug("Error occured: " + e);
},
_send: function (message) {
console.debug("Message Send: " + message);
if (this._ws) this._ws.send(message);
}
};
myWebSocket.connect();
setInterval(function() {
myWebSocket._send('msg1');
}, 5000);
Here is a JSFidlle
It may be that your support var is not behaving as you expect. The following code works in FireFox without closing the connection:
function ConnectWebSocket() {
if ("WebSocket" in window) {
myWebsocket = new WebSocket("ws://echo.websocket/");
myWebsocket.onmessage = function (evt) {
alert("onmessage");
}
myWebsocket.onopen = function () {
alert("onopen");
myWebsocket.send("a test message");
}
myWebsocket.onclose = function () {
alert("onclose");
ConnectWebSocket();
}
} else {
// Do something if there is no websockets support
}
}
ConnectWebSocket();
Example Fiddle
- You can use the tool on Websocket to make sure websockets are working correctly in your browser.
- Or (although your issue is with FF) you can use the steps listed here to debug websockets.
Try it.
var WS = window.WebSocket || window.MozWebSocket;
if (WS){
var websocket = new WS("wss://myserver/mychannel");
}
