== Rails Responds To Parent plugin

This is a responds to parent plugin that is compatible with rails 2 and rails 3. It is based off the original work by Sean Treadway and has updates from Nicolas Papon. This plugin is available as a ruby gem to aid plugins and applications using bundler to easily resolve dependency issues.

== Example

Controller:

class Test < ActionController::Base def main end

def form_action
  # Do stuff with params[:uploaded_file]

  responds_to_parent do
    render :update do |page|
      page << "alert($('stuff').innerHTML)"
    end
  end
end

end

main.html.erb:

  <form target="frame" action="form_action">
    <input type="file" name="uploaded_file"/>
    <input type="submit"/>
  </form>

  <iframe id='frame' name="frame"></iframe>
</body>
