A nice delete confirmation modal in Rails courtesy of Bootstrap

rails_bootstrap_delete_confirmation_modal.md

Some JavaScript

// Delete confirmation modals
$('#delete-confirm').on('show', function() {
  var $submit = $(this).find('.btn-danger'),
      href = $submit.attr('href');
  $submit.attr('href', href.replace('pony', $(this).data('id')));
});

$('.delete-confirm').click(function(e) {
  e.preventDefault();
  $('#delete-confirm').data('id', $(this).data('id')).modal('show');
});

Some HTML

<div class="modal fade" id="delete-confirm">
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Delete this thing?</h3>
  </div>
  <div class="modal-body">
    <p>Be certain, sonny.</p>
  </div>
  <div class="modal-footer">
    <%= link_to 'Delete', something_path+'/pony', method: :delete, :class => 'btn btn-danger' %>
    <a href="#" data-dismiss="modal" class="btn">Cancel</a>
  </div>
</div>

A well-crafted link:

<a href="#delete-confirm" data-id="<%= @something.id %>" class="delete-confirm btn btn-danger"><i class="icon-trash icon-white"></i></a>

Why not just use Bootstrap's modal functionality to pop open the confirm and also to grab the id?

<a href="#delete-confirm" data-target="delete-confirm-modal" data-id="<%= @something.id %>" class="delete-confirm btn btn-danger"><i class="icon-trash icon-white"></i></a>

And then do:

$('#delete-confirm').on('show.bs.modal', function(event) {
 var id = $(event.relatedTarget).data('id')
  var $submit = $(this).find('.btn-danger'),
      href = $submit.attr('href');
  $submit.attr('href', href.replace('pony', id));
});
