Rails :confirm modifier callback?

Question

I want to call a javascript function that will be conditional upon a user\'s response to the confirm box.

For example, I have the following anchor:

<%         


        

Answer 1

I had a similar issue (How to use inline :confirm option for html helpers with AJAX calls?). @Micah's answer, even though works, is not what "Rails 3 way" would be.

1. remote: true option needs to be added to the link_to helper, e.g.

link_to 'Sign Out', destroy_session_path, remote: true, confirm: 'Are you sure that you would like to sign out?', method: :delete

2. In the controller change respond_to block to answer to js

3. create a js file with the name that corresponds to your method, e.g. destroy_session.js.coffee

app/views/competitions/destroy_session.js.coffee:

jQuery ->
  $("form[data-remote]").on "ajax:success", (e, data, status, xhr) ->
    $(e.currentTarget).closest('tr').fadeOut()`

Hope that helps
