N00b question...but here it goes

Hey all,
How can I call a javascript function from my controller?
Is it possible to simply call a javascript function
from directly in the controller without needing an AJAX
request to come through via link_to_remote or remote form?

I’m not talking through an RJS link_to_remote AJAX etc.

As an example I’ve tried:

class RandomController < ApplicationController
before_filter :login_required, :except => [:index, :initialize]
def index
@session[:mode] = ‘view’
@map = GMap.new(“map”)

render :update do |page|
  page.call("resizeMap")
end

@map.control_init(:large_map => true, :map_type => true)
@map.center_zoom_init([38.539506, -121.757172],13)
store_location

end
end

This as expected does not work, it spits of the try{blah blah} catch
stuff.
Any help is greatly appreciated!
