I find this to be the best way. Worked everytime

 <%= javascript_tag "var obj = #{@obj.to_json}" %>

JSON is valid Javascript right out of the box, so why not just do:

var js_obj = <%= @rails_obj.to_json %>;

You need to escape all single-quotes then. ActionView has a helper for escaping JavaScript: ActionView::Helpers::JavaScriptHelper#escape_javascript
