all the tags take a :name parameter (and if they don't it's a bug)
which allows you to specify what http request parameter name to
use. all the tags also take an :id parameter, you can set that and
then use document.getElementById or whatever.

the form stuff (src/components/form.lisp) makes a lot of this easier,
you could look into those.

get-parameter sholud have been exported, my bad.
