Hi everyone, I''m having a bit of a hard time with the function periodically_call_remote. Here is my problem: I have a periodically_call_remote in a partial. With ajax, I do a replace_html of this partial for another partial, view/edit type of thing. The 2nd partial doesn''t contain a periodically_call_remote. The problem is that the browser CONTINUES to query the server even tho the periodically_call_remote shouldn''t be there anymore, because the partial changed. Does anyone know how to disable this behavior? Can I call something in my .rjs templates to disable/enablethe periodically_call_remote?

I hate replying to myself, but I just noticed somethign else. When I come back from my partial that does not have a periodically_call_remote to the one that has, the browser now queries the server TWICE. Once for the original periodically_call_remote, and once for everytime the partial is reloaded. This is not good... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Just replacing the html does not stop the js from executing. You have to use a condition variable for that. Like this: In the view partial to start the periodical call: <div id=''periodic''> <script>stop_polling = false;</script> <%= periodically_call_remote(:url => {:action => ''update_results''}, :frequency => 5, :condition => "stop_polling == false") %> </div> And in the controller to handle the update and turn off the periodic call: def update_results render :update do |page| page[''periodic''].replace_html :partial => ''results_table'' page.assign ''stop_polling'', true #<< here is the magick! end end Cheers- -Ezra --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Ahhh, exactly what I was looking for... Thank you very much
But Unfortunately I have another question :)
I do a periodically_call_remote with a timestamp, to see if the item
was modified ever since the last readout from the database.
What would be the best way to update the timestamp that
periodically_call_remove is called with when I update an item?
<script>stop_polling = false;</script>
<%= periodically_call_remote :url => { :action =>
:check_for_modifications, :id => @item, :readout_from_db =>
Time.now.to_i},
:frequency => VERIFICATION_DELAY,
:condition => "stop_polling == false"
%>
It is even possible ordo I have to refresh the entire page?
Thanks,
Jd
