Prototype's Ajax accepts a parameter called 'parameters' with an hash array for parameters (prototype doc) which would automatically be sent as GET or POST vars, but I could not find how to add items to that array using the Rails button_to_remote method. I could just add the parameters to the URL sent to the method, but that feels hacki...
I'm having a problem with some code I've written. I've had to anonymize it, but I can give the problem. This javascript runs inside an iframe, and is part of an object that gets instantiated.

I've come across these things in rich clients, such as Outlook and Acrobat, but my requirements are much simpler and must be web-based. Pretty layout, custom validation, complex fields and types are simpl...
