Enough niceties extended to the OP. It takes a sharp axe to split a tough
log¹:
This is not a free customer support forum; you are not a customer, and we
are not the customer support team that needs to cater to your every whim in
order to avoid losing you. This is a technical newsgroup on software
development for (aspiring) software developers. Do your own homework and
RTFFAQ, RTFM, STFW. Or FOAD, luser.

getElementsByName() is a method of the *Document* (HTML5+) and
*HTMLDocument* (W3C DOM Level 2 HTML, for [X]HTML < 5) interfaces only.

There is no getElementByID() method in the W3C DOM, which is probably the
reason why the call fails. getElementById(), however (note the letter
case), is and has always been a method of the *Document* interface.

[“Note: The getElementById() method is not on elements for compatibility
with older versions of jQuery. …” – WTF?]
