cfingerh,

You are close: look at ‘link_to_remote’ source
http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005056
, and you’ll see that it calls ‘remote function’
http://caboo.se/doc/classes/ActionView/Helpers/PrototypeHelper.html#M005063

In the view :

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

foo

In the controller:

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

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.
