Here is what I ended up with. It works for my purposes. function connect() { var ws = new WebSocket(‘ws://localhost:8080’); ws.onopen = function() { // subscribe to some channels ws.send(JSON.stringify({ //…. some message the I must send when I connect …. })); }; ws.onmessage = function(e) { console.log(‘Message:’, e.data); }; ws.onclose = function(e) { console.log(‘Socket … Read more
When the server reboots, the Web Socket connection is closed, so the JavaScript onclose event is triggered. Here’s an example that tries to reconnect every five seconds. function start(websocketServerLocation){ ws = new WebSocket(websocketServerLocation); ws.onmessage = function(evt) { alert(‘message received’); }; ws.onclose = function(){ // Try to reconnect in 5 seconds setTimeout(function(){start(websocketServerLocation)}, 5000); }; }
First let me address WebSockets readiness: WebSockets implementation of the Hixie-76 protocol are shipped and enabled by default in Chrome, Safari and iOS (iPhone and iPad). The Hixie-76 protocol is also shipped but disabled by default in Firefox 4 and Opera 11. The web-socket-js project is a Flash shim/polyfill that adds WebSocket (Hixie-76) support to … Read more
webSockets and regular sockets are not the same thing. A webSocket runs over a regular socket, but runs its own connection scheme, security scheme and framing protocol on top of the regular socket and both endpoints must follow those additional steps for a connection to even be made. You can see the webSocket protocol here: … Read more
What you are looking for can’t be done with in Javascript due to security constraints such as Distributed Denial of Service (DDOS) attacks. The closest technology available (that I know of) for client-side JS is WebRTC. With WebRTC you can use DataChannels over SRTP and ICE as a possible solution. See Also: How to send … Read more
Wanted to post this as a comment but the comment textarea is a bit restrictive Does the server send the data in chunks at the moment or is it one continuous stream? If you add a handler to the xmlHttpRequestInstance.onreadystatechange how often does it get triggered? If the xmlHttpRequestInstance.readystate has a value of 3 then … Read more
Is a struct’s address the same as its first member’s address? Yes, this is actually mandated by the C and C++ standards. From the C standard: 6.7.2.1-13. A pointer to a structure object, suitably converted, points to its initial member The size of your struct should be two bytes. You should not convert a pointer … Read more
