javascript - Rails form submission without refreshing the page? -

using play framework can create form user can fill out , submit, bringing javascript confirmation popup disappears after second, , doesn't refresh page. shown in video: https://www.youtube.com/watch?v=serfqiifhki

however, can't seem replicate in rails. i've tried using

<%= form_tag "/", :autocomplete => :off, :name => 'sentmessage', :remote => 'true', :id => 'contactform', :authenticity_token => true, :method => 'post' %> 

and in routes.rb

post '/' => 'home#submit_contact' 

finally, in home_controller.rb

def submit_contact     redirect_to '#contact' end 

and bring javascript confirmation popup, refresh page not want! there way replicate shown in video in rails?

since form remote form action should respond js / json response, rather redirecting new action

you can add these lines in controller action , define corresponding js template (submit_contact.js.erb file)

respond_to |format|   format.js end 

in js template can write javascript code.
