I'm looking to utilize the websocket protocol with JavaScript, can anyone provide guidance on

ws = new MozWebSocket("ws://localhost:8080/html5WebSocket/mywebsocket.do");

After trying the code snippet above to initiate a websocket request, I noticed that the connection was quickly closed and the onclose method was triggered.

ws.onclose = function(evt) {
        alert("close");
    };

In examining the network tab in Firebug, it displayed the request URL as http://localhost:8080/html5WebSocket/mywebsocket.do instead of ws://localhost:8080/html5WebSocket/mywebsocket.do as expected. What did I do incorrectly?

Answer №1

In the versions of Firefox 6-10, MozWebSocket was utilized. However, if you find yourself running a more recent release, opt for WebSocket as the constructor method.

Answer №2

When utilizing web sockets, it is common to notice a link to http://... due to the fact that the web socket handshake closely resembles an HTTP "upgrade" request.

The issue most probably lies on the server side rather than the client side.

Answer №3

When it comes to implementing real-time communication on the web, I rely on the "WebSocket" class in JavaScript. This method has proven to work seamlessly across Safari, Firefox, and Chrome browsers. Take a look at this snippet for reference:

var ws = new WebSocket(wsUrl);
ws.onopen = function() {
    ...
};
ws.onmessage = function(evt) {
   ...
};
ws.onclose = function() {
   ...
};

For backend operations, I typically utilize Tomcat & Jetty-Websocket servers (check out http://wiki.eclipse.org/Jetty/Feature/WebSockets for more information).
