Greetings,
I''m new to rails and currently having couple problems about how to add
javascript functionality into rails.
I have a simple method in the helper and i want to run this code on
button click.
------------------------------------------------------------------
module PagesHelper
def show_message
"simple output"
end
end
------------------------------------------------------------------
this doesnt work
<%= button_to_function "Print", "show_message()" %>
this doesnt work too
<input onclick=" show_message() " type="button"
value="PRINT" />
Can someone please show to properly solve this problem? I would really
apreciate it! thank you!

The `button_to_function` method''s second argument should be JavaScript, not Ruby.

Re: run simple method from Helper on button click
You cannot call Ruby code directly from client side. You have to send an AJAX request to some controller for this purpose.

Re: run simple method from Helper on button click
Suppose you have a controller HomeController. It should look like below.
home_controller.rb
class HomeController < ApplicationController
# GET /show_message
def show_message
format.js { render js: "alert(''simple output'');"
}
endend
and in your routs.rb file add this line
get ''/show_message'', ''home#show_message'',
as: :show_message
and in your view add this line
<%= link_to "Print", show_message_path, remote: true %>
After this when you click on Print link, and AJAX request will be sent to
HomeController''sshow_message action and it will display a javascript
alert.
For better understanding of AJAX requests in Rails, follow this tutorial -
http://www.tutorialspoint.com/ruby-on-rails/rails-and-ajax.htm :)
