I have a Ruby hash which is passed to a hidden field. How do I extract this hash into JavaScript arrays that I can work with? I need to access the key/value pairs in JavaScript.

Use my_awesome_ruby_hash.to_json and then you can simply either eval it in js or use parseJSON. You might need to require 'json' (not in Rails).
