It is possible to get data from a webpage into your processing sketch. I know how to get pictures from the internet into the skecth or how to link to a website. But can you go the other way around? Is it possible to for example type a name in my processing sketch and send it to a website where I can see the name I typed in my sketch?
Hi,
One way of doing this is to use WebSockets, which is an extension of the HTTP protocol but full-duplex which means that both the server and the client can exchange in both directions without having to open and close a new connection.
This is great for real time interaction between two processes/machines over a network.
Seems like there’s already a Processing library to do that!!
And creating a WebSocket client application in JavaScript is very easy :
So when you type something on the Processing sketch, you send a JSON message through sockets with the event or the full text and in the client web page, you update the text dynamically through DOM manipulation
