Ajax in layout?

Rails
1

Hai frnds,
Can we add ajax functionality in a layout?
I was wondering if someone has an answer for that. In my layout current
time is displayed.But if the time needs to be updated we have to refresh
the page.I want it using ajax.

Thanks,
Veena

<%= observe_field :suggest, :url => { :action => :find_suggestion },
:frequency => 0.25,
:update => :suggest,
:with => ‘q’
%>
it will refresh the id “suggest”

if you cann’t understand
you can also find observe_field method
