Subject: pass def to eval

Hello,

My plan is to have a ruby class with a variety of functions in it and I
want to be able to call functions from this class using AJAX. I think
the easiest way to do this then is to pass a cgi parameter named
function or soemthing with the value being the def I wish to call.

So something like this

// this contained in test.rb

def test(x)
  print x
end

from .js file

url = test.rb?action=test('help');
xmlObject.open("get",url,true)
xmlObject.send

anyway something like that and then in test.rb I want to have something
like

if params.has_key?("action")
  eval(params["action"])
end

and hopefully it would return "help". Please let me know if this is the
best way to do this and also if I am being unclear I am more than happy
to clarify.

I have tried something like the above technique and nothing is being
returned to the XmlObject.

Thank you
