How do you call a javascript function to do something when the response  
is returned to the visitors browser?

Easy ey?

Many of the built-in AJAX actions in Rails such as the link\_to\_remote  
allow you to specify JavaScript to execute upon completion by setting  
the :success attribute. In this example, I show the spinner div while  
the processing occurs, and hide it when it is complete.

\<%= link\_to\_remote( “#{state.title}”,  
:update =\> “state\_editor”,  
:before =\> %(Element.show(‘spinner’)),  
:success =\> %(Element.hide(‘spinner’)) ,  
:url =\>{ :action =\> “load\_state”, :id =\> state.id }) %\>

Hope this helps ~

Ben

success/failure attribute?

Thanks in advance

More info on what Im trying to do:

I submit a login form using ajax.  
On the server side I check if the submitted info is valid.  
Depending on if the submitted info is valid or not I send back different  
partials.

If the info was invalid I would like to set the failure attribute so  
that I can pop up a javascript alert in the browser.

Is this doable?
