Hi. My main intention is to keep the functionality independent form the Javascript, to have it gracefully degradable. Maybe I am trying to go where I want the wrong way but the main idea is: there are some jQuery UI tabs and when the user presses a link, a new tab is added corresponding to that action $("#tabs").tabs('add', "/groups", "My Groups"); the controller identifies the AJAX request and renders only the partial for that tab if request.xhr? render :partial => "index_tab" end at this point I would like the Javascript file associated with the /groups/index action to be executed as well, meaning the index.js.erb file in the groups folder. because of the "only one render" rule I couldn't think of a nice way to do it and I am in need of a fast solution. Thank you for any suggestions you might have.
