E.g. for buttons to clear forms or print them, sometimes to generate
validation codes for filled out forms.

I think so, since there are documents, which check if the document
viewer is the Adobe Reader and display an error message instead of the
document if that is the case. If my understanding is correct, that
works by executing some Javascript code automatically and the real
document is only shown, if the code was executed and did return the
expected result.
