Re: Transmitting a javascript-value to the server using JSON
Well well, looks like Chenillekit's OnEvent is pretty close to what I want. I think you still got to make your Javascript thing a component though, but otherwise it functions similarly to T4's EventListener.

Re: Transmitting a javascript-value to the server using JSON
Dear Toby, thanks for your comments on this. But I decided to use a hidden form field (from t5components) and fill it with the offset-value using javascript. It seems to me that this is the simpler solution. I described the details in another thread (subject: Getting users timezone-offset (javascript). Nevertheless I would very much appreciate a simple T5-support for transfering values from the client to the server.

Re: Transmitting a javascript-value to the server using JSON
Hello Peer, Sure it can be done ... have a look at JSON.stringify() at http://www.json.org/js.html, this will turn the Javascript object into JSON text. On the server-side you need to use JSONTokener and JSONObject see http://www.json.org/java/index.html to convert back to a Java object If you need more help let me know Regards Toby 2008/8/5 Peer Brink [EMAIL PROTECTED] Hello, I try to transmit the users/browsers timezone-offset to the server.
