You might be able to do this using AJAX, where the server sends back  
some Javascript to execute in the browser.

In your message you say absolutely nothing about your environment.  
However, the mention of flas(h)[:notice] suggests you are using Rails.  
In that case, I’d say that the Rails mailing list is an appropriate  
place to ask the question.
