Confirm dialogs using Twitter Bootstrap

branch: master


This gem adds some javascript to change the default behaviour of data-confirm processing.

The normal confirm dialog shows a text with buttons 'ok' and 'cancel'. More information is needed here for a user to make the right decision. This gem therefore also adds:

  • data-confirm-fade (default: false)
  • data-confirm-title (default:
  • data-confirm-cancel (default: 'cancel')
  • data-confirm-cancel-class (default: 'btn cancel')
  • data-confirm-proceed (default: 'ok')
  • data-confirm-proceed-class (default: 'btn-primary')

This behaviour is similar to that of a "regular" confirm box in ways that it uses the same title and button labels. Defaults can be changed in two ways:

Changing all default values:

$.fn.twitter_bootstrap_confirmbox.defaults = {
    fade: false,
    title: null, // if title equals null is used
    cancel: "Cancel",
    cancel_class: "btn cancel",
    proceed: "OK",
    proceed_class: "btn proceed btn-primary"

Only changing one default value:

$.fn.twitter_bootstrap_confirmbox.defaults.proceed_class = "btn proceed btn-success";


Add this line to your application's Gemfile:

gem 'twitter-bootstrap-rails-confirm'

Or for Bootstrap 3 support:

gem 'twitter-bootstrap-rails-confirm', github: 'bluerail/twitter-bootstrap-rails-confirm', branch: 'bootstrap3'

And then execute:

$ bundle


Add it to your application.js, anywhere after you require jquery_ujs:

//= require twitter/bootstrap/rails/confirm

Next... nothing. There is nothing you need to do to get this working. A helper could be useful for handling large amount of destroy buttons:

def destroy_link_to(path, options)
  link_to t('.destroy'), path, 
    :method => :delete,
    :class => "btn",
    :confirm => t('.destroy_confirm.body', :item => options[:item]),
    "data-confirm-fade" => true,
    "data-confirm-title" => t('.destroy_confirm.title', :item => options[:item]),
    "data-confirm-cancel" => t('.destroy_confirm.cancel', :item => options[:item]),
    "data-confirm-cancel-class" => "btn-cancel"),
    "data-confirm-proceed" => t('.destroy_confirm.proceed', :item => options[:item]),
    "data-confirm-proceed-class" => "btn-danger"
