Could someone please demonstrate the code to send both json (or xml) AND javascript (to be executed) in a single Ajax request?

If you set the X-JSON header to be a json fragment Prototype (don''t know about other libraries) will deserialize that for you, and then the response body can be whatever you want. Personally if I''ve already written stuff to take a JSON response and do stuff based on that data, I wouldn''t want to also send back javascript fragments - I''d just write the client side code to do the desired action if the appropriate content was in the response JSON Fred> Is this even possible? > -- > Posted viahttp://www.ruby-forum.com/.-- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
