I am very familiar with controllers/views/helpers the way you just
specified, but it doesn't help me because here is my context:
I am using ajax function from JavaScript, as a response to a certain event
on the page. This ajax is called with :eval option which allows me to
construct actual JavaScript string to be executed (the one that in my
example represented by result+=...); the reason I can't use a regular JS
ajax call which replaces html element is because I specifically need to
update multiple targets, so :eval is my only option). I can't use regular
{{...}} embeds either, because I can't reload the page - need to update
multiple html elements on the fly, in ajax mode.
That's why my only option seems to be constructing JavaScript which
executes the necessary updates on the page as a sequel to JavaScript
ajax(:eval) call. This is exactly how I ended up constructing JavaScript in
my controller function and the need to mix in some web2py objects in it.
