You may want to consider JSON. I don't know much about Ruby, but JSON is the simplest format to use if you're just going to be converting the results to JS objects anyway. Regardless of the language you use, you'll have to pick a method for returning the data. There are any number of possibilities, but 3 main ones are:
1) Pure HTML
2) JSON
3) XML
Each has advantages, but 1) is good for pure HTML inserts, 2) is good when you want to do further manipulation of the results client-side and 3) is good if you're planning to re-use the code for something like web-services, where other applications need to use the same interface.
[1] "But don't know if I'd need JSON to do this within Rails ?" Regardless of language, you'll have to eventually use JSON if you want that simple ability of grabbing a JS object from the server. Now, whether or not Rails can abstract that away, I'm not sure
[2] I'd check out http://en.wikipedia.org/wiki/Talk:JSON. YAML is a serialization in Ruby that is somewhat related to JSON. Again, not being a Ruby developer, I can't give you the details, but also check http://redhanded.hobix.com/inspect/yamlIsJson.html
Good luck,

Hi all,
I'm building an application which uses mostly ajax to update the
sections of the page. Now I've come to some thoughts on how to make the
ajax-handling more efficient / less buggy.
Currently, when the page loads up, I start some "new Ajax.Updater"-stuff
to fill some sections with content from the db. I also registered
watchers which also start nearly the same ajax-calls as on inital
page-loading.
Now I've come to a point where I want to reduce the ajax-calls, because
many of the contents is already there (in a session e.g.) or i will
preload it. From the server-results I want to create _javascript_-objects
dynamically and show them when a particular link is clicked.
Are there any ressources on the web explaining on how to fill the
content coming from ajax into _javascript_ objects ? [1] I'm pretty new to
the prototype stuff. And I use Rails, so maybe there's a cool solution ?

Thx!

[1] Just discovered
http://particletree.com/features/preloading-data-with-ajax-and-json/
But don't know if I'd need JSON to do this within Rails ?
[2] Concerning Rails:
http://www.codyfauser.com/articles/2005/11/20/rails-rjs-templates
May this be the solution ?
