You should use JSON.stringify in Javascript, which takes either an array or hash as its argument (since these are the only valid JSON constructions). It returns a form which is the Javascript object serialized to JSON.

On the Ruby side, you'll receive a JSON encoded string, so you'll need to require 'json' (this is done automatically in Rails) and use JSON.parse(string). This will give you a Ruby object.
