authblk 包中的自定义脚注

Question

我想创建一个特殊的脚注，以便将多个位置映射到同一个脚注。这在其他地方有介绍（不同的地方引用同一个脚注)，但我在尝试将其与 authblk 包一起用于作者列表中时遇到了麻烦（自定义脚注是\CoAuthorMark）。其他方面可能存在问题，但我还没有进行实验。

或者，有没有办法用 \thanks 来做到这一点？

\documentclass[letterpaper]{article}
\usepackage[affil-it]{authblk}

\usepackage[english]{babel}
\usepackage{blindtext}


\title{An efficient method for exploiting midichlorians in weak life-forms}

\author[1,2]{Darth Vader\footnote{Contributed equally.}}%

\newcounter{CoAuthor}

% The order may be wrong on these next two:
\setcounter{CoAuthor}{\value{footnote}}
\edef\CoAuthorMark{\footnotemark[\value{CoAuthor}]}

\author[2,3]{Darth Sidious\CoAuthorMark%
  \thanks{Electronic address: \texttt{[email protected]}; Corresponding author}}

\affil[1]{Office of the Supreme Commander of the Imperial Forces, The Galactic Empire, The Bridge, Executor}
\affil[2]{Order of the Sith Lords, LiMerge Power Building, The Works, Coruscant}
\affil[3]{Office of the Emperor of the Galaxy, The Galactic Empire, 1000 Imperial Palace, 2 Main St. Coruscant}


\date{\today}

\begin{document}

\maketitle
\blindtext
\end{document}

我收到的上述错误消息是：

! Missing \endcsname inserted.
<to be read again>
                   \c@CoAuthor
l.16 ...AuthorMark{\footnotemark[\value{CoAuthor}]
                                                  }

但我通常会得到这样的信息：

! Use of \\author doesn't match its definition.

Answer 1

新的计数器似乎没有必要，因为您只使用 的当前值footnote；也\footnotemark应该在 中受到保护，\edef并且\value{CoAuthor}应该是\arabic{CoAuthor}，因为\value{CoAuthor}不会扩展到数字，而只会扩展到计数器的内部名称。

\edef事实上，你根本不需要。

最后，\CoAuthorMark必须加以保护\author。
