Can someone inform me about the background of the onsubmit HTML event
and submit() JS method? Reason I ask is because I notice when the submit
method is executed in JS, the onsubmit HTML event is not executed.  The
following code below was a piece of sample code I created to test this
theory (test-JSsubmit-finish.asp was just a page that contained 'Hello'
on it; nothing really important).

Was this functionality created on purpose by W3C (I'm assuming the
onsubmit HTML event came before the submit() method in JS)? If so, why?

Thank you.
