are there a few basic ways to do AJAX on Rails? or is it open ended…
just like using MFC to write a Win32 app… you can do it any way you
want.
right now I see two ways to update content using AJAX on Rails:
one is to
link_to_remote or form_remote_tag
with the :update option to update the DOM_Object.innerHTML with the
action code returned.
the other is to
link_to_remote or form_remote_tag
and just call to the action, update the data, and then let the RJS
handles the rest.
