In this answer, I created two commands \footnotenumber
and \multifootnote
for writing footnote with multiple numbers. The problem with these commands is that hyperlinks do not work as in usual footnotes: for example, if you click on the red boxed "1" in the document generated by the code below, nothing would happen.
I tried to use \hyperlink
and \hypertarget
in these commands without success. To me the difficulties are: 1) I don't know much about the internal of \footnotemark
, thus have no idea where to place the \hyperlink
ed number/mark; 2) in the \clist_put_right:Nn
line, if I use \ref*{ ##1 }
as the text of a \hypertarget
, there shall be multiple errors like Undefined control sequence. \@hyper@@anchor ...r@spot {#2#3}\let \put@me@back
.
Thus my question is that, what should be done to make the hyperlinks work? Any suggestion is greatly appreciated!
\documentclass{article}
\usepackage{hyperref}
\ExplSyntaxOn
\NewDocumentCommand \multifootnotemark { O{} }
{
\footnotemark
\group_begin:
\tl_if_blank:nF { #1 }
{
\addtocounter { footnote } { -1 }
\refstepcounter { footnote }
\label { #1 }
}
\group_end:
}
\NewCommandCopy \footnotenumber \multifootnotemark
\NewDocumentCommand \multifootnotetext { O{} m }
{
\group_begin:
\tl_if_blank:nF { #1 }
{
\clist_clear:N \l_tmpa_clist
\clist_map_inline:nn { #1 }
{
\clist_put_right:Nn \l_tmpa_clist { \ref*{ ##1 } }
}
\def \thefootnote { \clist_use:Nn \l_tmpa_clist { , } }
}
\footnotetext { #2 }
\group_end:
}
\NewCommandCopy \multifootnote \multifootnotetext
\ExplSyntaxOff
\begin{document}
Lorem ipsum\footnotenumber[fn1] dolor sit amet\footnotenumber[fn2], consectetur adipiscing elit\footnotenumber[fn3].
\multifootnote[fn1,fn2,fn3]{Test footnote.}
\end{document}
