Did you try ending your completion text with "\<Left>" e.g. :return
"document.getElementById()\<Left>" (with double quotes and a backslash
before the less-than sign)? (I haven't, so I don't know if it works.)

See
:help expr-quote
:help complete-functions

Jimmy Carter cited this Jewish saying in his concession speech at the
end of the 1980 election. At least he said it was a Jewish saying; I
can't find it anywhere. I'm sure he's telling the truth though; why
would he lie about a thing like that?
