General ⇒ How can we make hyperlinks for footnote?

[ggyyree]

How can we make hyperlinks for footnote? I use hyperref package and the codes below but I got not hyperlinks for footnotes. Any suggestions? Thanks a lot!

Code: Select all

hyperfootnotes = true

Code: Select all

\footnotemark[1]
\footnotetext[1]{nnn}

There two points to be taken into account.

• Load hyperref as the very last package. There are only a few packages to be loaded after (see next point).
• When using tabularx in conjunction with hyperref, load tabularx after hyperref.

If these suggestions don't help, provide your complete preamble. There may be other package that cause conflicts with hyperref.

It's solved. Thanks a lot!!!

Remember the first point of my list.

I have put the hyperref at the last of the preamble but it doesn't work...

Hi,

have a look at the hyperref README file, the footnote support is explained near its end, further it provides a compilable example demonstrating hyperlinks even with \footnotemark and \footnotetext.

Yes, thanks a lot! I have tested with the nasty example. It works! But it doesn't applicable for my report because I use the \footnotemark inside a table. What I did is like following and anything wrong?

Code: Select all

\makeatletter
\begin{center}
\setlength{\floatsep}{10pt plus 3pt minus 2pt} 
\begin{tabular}{c||p{4.2cm}|p{4.2cm}|p{4.2cm}}
\toprule
N &aaa &bbb &ccc \footnotemark  \let\saved@Href@A\Hy@footnote@currentHref \\
\midrule
N &111 &222 \footnotemark \let\saved@Href@B\Hy@footnote@currentHref &333
\bottomrule
\end{tabular}
\tabcaption{\small\bf\it Table}
\label{table:Table1}
\end{center}

\addtocounter{footnote}{-2}%
  \let\Hy@footnote@currentHref\saved@Href@A
\footnotetext[1]{Test1}
  \addtocounter{footnote}{1}%
  \let\Hy@footnote@currentHref\saved@Href@B
\footnotetext[2]{Test2}

Nasty example:

Code: Select all

\documentclass{article}
\usepackage{hyperref}
\begin{document}
\makeatletter
A%
  \footnotemark
  \let\saved@Href@A\Hy@footnote@currentHref
  % remember link name
B%
  \footnotemark
  \let\saved@Href@B\Hy@footnote@currentHref
b%
  \addtocounter{footnote}{-1}%
  \addtocounter{Hfootnote}{-1}% generate the same anchor
  \footnotemark
C%
  \footnotemark
  \let\saved@Href@C\Hy@footnote@currentHref
  \addtocounter{footnote}{-2}%
  \let\Hy@footnote@currentHref\saved@Href@A
\footnotetext{AAAA}%
  \addtocounter{footnote}{1}%
  \let\Hy@footnote@currentHref\saved@Href@B
\footnotetext{BBBBB}%
  \addtocounter{footnote}{1}%
  \let\Hy@footnote@currentHref\saved@Href@C
\footnotetext{CCCC}%
\end{document}

Code: Select all

\begin{center}
......................
N &aaa &bbb &ccc \footnotemark  \let\saved@Href@A\Hy@footnote@currentHref \\
.....................
N &111 &222 \footnotemark \let\saved@Href@B\Hy@footnote@currentHref &333

The \let commands need to be \global to take effect out of the group where they lie and \footnotetext has an optional argument.

The following code defines and exemplifies the commands \Footnotemark and \Footnotetext to automatize tasks. You can always use them instead of \footnotemark and \footnotetext, except when the optional argument of these commands is required. Instead of having to manually define \saved@Href@A, \saved@Href@B, \saved@Href@C, etc., \Footnotemark defines \saved@Href@<aa>, where <aa> stands for an alphabetic version of the footnote counter. For preventing the case of more that 27 footnotes, this is done with the \alphalph command defined in the alphalph package. If you never have a large number of footnotes, the code can be slightly simplified.

Code: Select all

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{alphalph}
\usepackage{booktabs}
\usepackage{hyperref}

\makeatletter
\newcommand{\Footnotemark}{\footnotemark%

    \Hy@footnote@currentHref}
\newcommand{\Footnotetext}[1]{%
   \expandafter\let\expandafter\Hy@footnote@currentHref\csname saved@Href@\alphalph{\value{footnote}}\endcsname%
   \footnotetext{#1}}
\makeatother

\begin{document}

\setcounter{footnote}{35}

Text before the table\footnote{A usual footnote.}. The number of the first footnote is \thefootnote.

\begin{center}

      N &aaa &bbb &ccc\Footnotemark \\
      \midrule
      N &111 &222\Footnotemark   &333\Footnotemark \\
      \bottomrule
   \end{tabular}
\end{center}

\addtocounter{footnote}{-2}\Footnotetext{First footnote in the table}
\stepcounter{footnote}\Footnotetext{Second footnote}
\stepcounter{footnote}\Footnotetext{Third footnote}

Text after the table\Footnotemark\Footnotetext{Footnote done with 
\texttt{\textbackslash Footnotemark} and \texttt{\textbackslash Footnotetext}.}
Text after the table\footnote{Other usual footnote.}.

Yes, it works quite well! Thank yo very much! However, I also met a problem that two footmarks need to be referred to the same footnote. How to do that please?

What I want is something like below, the footnote for "ccc" and "111" are the same.

Code: Select all

\begin{center}
N &aaa &bbb &ccc \footnotemark[1]\\
N &111 \footnotemark[1] &222 \footnotemark[2] &333
\end{center}
\footnotetext[1]{Test1}
\footnotetext[2]{Test2}

What I did is like following and anything wrong?

Code: Select all

\begin{center}
......................
N &aaa &bbb &ccc \footnotemark  \let\saved@Href@A\Hy@footnote@currentHref \\
.....................
N &111 &222 \footnotemark \let\saved@Href@B\Hy@footnote@currentHref &333
.....................
\end{center}
.....................
\footnotetext[1]{Test1}
 .....................
\footnotetext[2]{Test2}

I am sorry to bother again but how to change the color of the footmark now please?

I did and it doesn't work:

Code: Select all

\color{red}\Footnotemark\color{black}
