It's possible to fetch the code from a REPL tag as described by Jeff in the comment, but it'd be ideal to have an official API implemented.

Original issue:
I know this is not something directly PyScript related, but is there a way of getting the current code in a py-repl via JS? I am working on something and that is needed. I understand it would probably be as simple as getting the text in an element, but what element would that be? Another thing: can you preload code into a REPL so it is not needed to be typed out every time you load the page?
