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

</div>

\<%= 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
