Setting a Ruby Variable inside Jquery

Question

I have a ruby varibale $text = "abcd" I have some condition inside my jquery according to which this text should change. This is so far i have tried.. but no luck.

$("#xyz").click(function() {
  new_text = 'efgh';
  "<% $text = new_text %>"
}

Is this possible. Thanks in advance.

ruby is server side... you can't do something like that unless using ajax... — Reigel Gallarde, Jun 06 '14 at 09:25
but i can set a string directly.. if that is possible i can pass new_text right? — Nidhin S G, Jun 06 '14 at 09:37
Indirectly you can achieve this. See http://stackoverflow.com/questions/4959770/how-to-pass-a-javascript-variable-into-a-erb-code-in-a-js-view/14643289#14643289 — Thaha kp, Jun 06 '14 at 09:41

EDIT - Realize this is the opposite of what you want! instead of deleting, it may help someone so I'll leave...

You could use the gon gem (Railscast) -

#Gemfile
gem 'gon', '~> 5.0.4'

#app/controllers/your_controller.rb
class YourController < ApplicationController
   def method
      gon.push({
          var_name: "value"
      })
   end
end

#app/views/layouts/application.html.erb
...
<%= include_gon %>

#app/assets/javascripts/application.js
alert(gon.var_name);

No problem - hope it helps! – Richard Peck Jun 06 '14 at 12:17 — Richard Peck, Jun 06 '14 at 12:17
