sending javascript to browser widget?

I'm going to say that Javascript is written to prevent you from doing that. Javascript sandboxes their commands and functions so that only certain ones are visible from outside the applications "sandbox". They call it Scope and Context. 

Here is a good article on it which helped me understand why I could not access certain commands and functions outside Acrobat:

If you can set a username and password in a web page javascript control, then you can probably GET them too. The reason why plugins like password managers work is because they operate inside the context of the browser application itself. Of course, all of my posts are subject to scrutiny and correction.
