Text frame with onClick Event (interactive PDF)

Good morning,

I have to create a "checklist" for our office and would like to add a text frame with a onClick event behaviour. My idea is that
after exporting as an interactive PDF file the user can click (or double-click, doesn't matter) on this specific frame and it should
auto-complete this field with date and the windows login name. Is this possible and if yes, how can I do this?

What I've got so far is this command
--> alert($.getenv("USERNAME"));
which returns the actual logged in user but I'm struggeling with the onClick event (javascript is not really my business)

Thank you in advance
Kind regards
Moritz
