Almost every line has a comment explaining what it does, so the code should speak for itself. This code will generate the following JavaScript:
| Code Block | ||
|---|---|---|

<script type="text/JavaScript"> |
...
function handleMsg(eventType, msg) { |
...
if(eventType == DDSocketApp.MessageEvent) { |
...
$('#LOC__Received').val( $('#LOC__Received').val() + msg.data + '\r\n');} |
...
} |
...
var ws = new DDSocketApp.SocketBase('ws://127.0.0.1:89/WSDemoPage', handleMsg ); |
...
if(!ws.supported()) { |
...
alert('Sockets are not supported.') |
...
} |
...
else { |
...
ws.connect(); |
...
} |
And that completes the app. It should look like this:
As soon as you open this url in a second browser, this browser window will be immediately notified that a new client has connected. All messages that you send from either window, will appear in both windows. And there you have it, a very simple websocket application!
