Hi!

My overall goal is to be able to allow someone with a touchscreen device (iPhone, for example) to be able to connect to a website running javascript, and for their touch coordinates (x, y) to be sent to a Processing sketch. I know that if I can get the below working (sending 'hi' from a .js client to a Processing server), that I will be set.

My current approach is to run a server in the Processing sketch and try to send data via Javascript. However, the output is a little off (shown below). Any ideas or suggestions are greatly appreciated.

The javascript (it uses http://socket.io/):

1. <script src="http://cdn.socket.io/stable/socket.io.js"></script>
   <script type="text/javascript">
   var socket = new io.Socket('localhost',{
               port: 10002
           });
           socket.connect(); }
   
           socket.send('hi');
2. </script>
   

The Processing (an example straight from Processing.org):

1. // Example by Tom Igoe
   
   import processing.net.*;
   
   int port = 10002;      
   Server myServer;       
   
   void setup()
   {
     size(400, 400);
     background(0);
     myServer = new Server(this, port);
   }
   
   void draw()
   {
     // Get the next available client
     Client thisClient = myServer.available();
     // If the client is not null, and says something, display what it said
     if (thisClient !=null) {
       String whatClientSaid = thisClient.readString();
       if (whatClientSaid != null) {
         println(thisClient.ip() + "t" + whatClientSaid);
       }
     }
   }

The resulting output server-side:
