One of the easiest ways is to use js.erb file, where you can do ruby tags to access variables that you defined in the controller action.

You need to use a respond_to block in the controller action, specifying the action to be able to respond to javascript.

items_controller.rb

class ItemsController < ApplicationController

  def action
    respond_to do |format|
      format.js
      #format.html {}    #  These are for allowing other types of formats to be responded to.
      #format.json {}    #  But they are not necessary for using this js.erb way of doing things.
    end
  end

end

/views/items/action.js.erb

$(div).html('The cat has erased your page');
