How about using observe_field, and triggering some kind of action every .2 second that counts how many characters there are, then updates some kind of div? Note that I don't know exactly how this works, so you may be going back to your server every .2 seconds to get an update. If you're lucky, the action will be embedded in your page and it'll be done on the client-side.. But Marnen is right, this is, at the core, a Javascript question. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
