How to get HTML code after rendering a view on rails

Question

I want to get the render "xxx" 's final HTML code to do something. I can change the file encoding from utf-8 to gb2312 then response it.

My question is, how to achieve this?

using javascript and the DOM? not sure I understand what you want though. — jcomeau_ictx

You probably want an after_filter for something like this. Maybe along the lines of

  class ChangeEncodingFilter
    def self.filter(controller)
      controller.response.body = change_encoding(controller.response.body)
    end
  end

  class YourController < ActionController::Base
    after_filter ChangeEncodingFilter
  end

where you'll provide the change_encoding method to do the actual work.

Actually, it'll probably require mutation of other things in the response, but the point is that an after_filter can do things with the response just before it's sent.
