application.js

$(function() {
  
  $(".flash").livequery(function(){
    $(this).delay(5000).fadeThenSlideToggle();
  });

});

create.js.erb

<% if @item.valid? %>
  jQuery("#some-element").prepend("<div class='flash notice'>Item created!</div>");
<% else %>
  jQuery("#some-element").prepend("<div class='flash error'><%= escape_javascript(render('shared/error_messages', :target => @item)) %></div>");
<% end %>

Interesting to see other ways to do it. In my case, I have flash messages appearing in various areas so I don't use an id for the flash...though I might change to a single flash area. I'm wondering with your example here if since you presumably always have the div#flash available on the page that you could just replace the text in update_flash instead prepending...

var update_flash = function(message) {
  $('#flash').text(message).slideDown(1000).delay(5000).slideUp(1000);
}

Otherwise it seems like you will end up with multiple elements with the same ID.

Oh, duh. Well, it's not always available, hence me writing it that way, but I either need to check for its availability or I need to make it always available.

Well, I probably never would have noticed, but was just recently dealing with a #flash in a single place.
