HTML5 Web Sockets are awesome! I've been toying around with it for a bit today and noticed that not every browser supports native HTML5 Web Sockets yet.
|
||
|
|
||
|
Google Chrome 5 has native support for web sockets, FireFox 3.6 does not. This poses a problem if you're building something awesome that does require web sockets.

Luckily, it's easy to detect web sockets support through JavaScript. All you really need to do is check if `WebSocket` is defined or not.
|
||
|
|
||
|
Here's a simple example, note that I'm using jQuery here.
|
||
|
|
||
|
:::javascript
|
||
|
$(document).ready(function() {
|
||
|
if( typeof(WebSocket) != "function" ) {
|
||
|
$('body').html("<h1>Error</h1><p>Your browser does not support HTML5 Web Sockets. Try Google Chrome instead.</p>");
|
||
|
}
|
||
|
});
|
||
|
|
||
|
Maybe there are better ways, but _it works for me_.
