You are close: look at ‘link\_to\_remote’ source  
[http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005056](http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005056)  
, and you’ll see that it calls ‘remote function’

## In the view :

\<a onmouseover=“\<%= remote\_function(:url =\> { :action =\> :bar }) %\>”

> foo

## In the controller:

def bar  
render(:update) { |page|  
page.alert(‘bar’)  
}  
end

</div>

When would doing something like that be useful or better than just  
embedding  
the javascript?

Maybe if the stuff that you’d be mousing over was dynamic rather than  
static?

Just curious.
