If you're going to use Erb in your JavaScript, then you must name your file
whatever.js.erb. Then your <%= %> will expand to be whatever the local value of
@user is at the moment that script is requested. You will need a controller,
too, and your request will need to have some context around it. If your
controller had a respond_to block in it, and your JavaScript file was named
sensibly for the controller method, then this would Just Workâ˘,
respond_to do |format|
format.js { render :layout => false }
format.html
end
