module Ckeditor
  class Instance

    private :capybara

    def initialize(instance_id, capybara)
      @instance_id, @capybara = instance_id, capybara
    end

    def val(value)
      capybara.execute_script "jQuery('textarea##{@instance_id}').val('#{value}')"
    end

    def reload_all
      capybara.execute_script "for(var instance in CKEDITOR.instances) { if(CKEDITOR.instances.hasOwnProperty(instance)) {CKEDITOR.instances[instance].destroy(true);} }"
      capybara.execute_script "CKEDITOR.replaceAll();"
    end
  end
end
