Hi, I have some calculation to do in some part of my ruby-rails application, I wish to show a “waiting message” whilw rails is calculating the result and when the result is already, I can remove the waiting message and put the final result. I have no idea how I can do this. can some one give me a clue??? Thanks you very much Sayoyo ---

Hi, Thanks you very much for the info. But, we have already tried, but it doesn’t really what we need, since we have to tell the users how many percentage the task has been completed, ajax just allow us the change the html contain once, but not a interval of time… also, we render to a new /controller/action when the calculation happens. so ajax can’t hardly apply here, Thanks you very much for the information Saiho Daniel Owen van Dommelen wrote: > sayoyo wrote: > > > Hi, > > > > I have some calculation to do in some part of my ruby-rails application, > > I wish to show a “waiting message” whilw rails is calculating the result > > and when the result is already, I can remove the waiting message and put > > the final result.

Just check the second page of the tutorial it speaks of it a little… Consider this little extract from the tutorial: Live Search: \<%= text\_field\_tag :searchtext %\> \<%= observe\_field(:searchtext, :frequency =\> 0.25, :update =\> :search\_hits, :url =\> { :action =\> :live\_search }) %\> Search Results: Just check the Internet a little for some info. Since I’m currently actually learning Rails (have to know enough to work in it by monday) I can’t really help you specifically, but Ajax is definately the way to go here, I believe anyway… ---

Hi Daniel, Once again thanks you for the informatin, however, “the interval” you have mentionned works on a specific html component(oberver field), I’m really not sure that it will work on a currently running rails processus (I may be wrong), what we are trying to do is gathering information from user, than compute the information, to activate the computation, we use a normal “rails-button” from a form it means, it will send the result on a new /controller/action. but between the old /controller/action and the new one, there will pass a several seconds, 10 -20 sec. but since the “post/get” is already send to server, the browser is waiting… and we would like to have some “waiting message”, just want to keep the user eye busy… Thanks you bery much Saiho Daniel Owen van Dommelen wrote: > sayoyo wrote: > > > Hi, > > > > Thanks you very much for the info.

there is a rjs tutorial from oreilly for 6 bucks… i highly recommend it because it shows how awesome it is to use rjs + ajax. sayoyo wrote: > Hi, > > I have some calculation to do in some part of my ruby-rails application, > I wish to show a “waiting message” whilw rails is calculating the result > and when the result is already, I can remove the waiting message and put > the final result.

I think what you are after goes under the title “Progress Bar”. Maybe search the web for that. Stephan
