Thanks Chris, this looks great !!

But I just have one problem, the modal does not close with the buttons (cancel or ok).

To solve it, I just change the last functions :

$("#modal1 .close").on("click", function() {
  return $("#modal1").fadeOut(function() { $(this).remove(); });
});

return $("#modal1 .confirm").on("click", function() {
  $("#modal1").fadeOut(function() { $(this).remove(); });
  return $.rails.confirmed(link);
  
});

I also made some updates to have a background and slideUp/slideDown animations if you need it :
