elsarticle 课程：如何获取没有框的彩色链接？

Question

我正在使用这个elsearticle类。目前，链接（引文、公式引用等）放在彩色框中，我宁愿让链接有颜色，而不是框。所以我尝试把

\usepackage{hyperref}
\usepackage[hyperref]{xcolor}
\hypersetup{
  colorlinks   = true, %Colours links instead of ugly boxes
  urlcolor     = red, %Colour for external hyperlinks
  linkcolor    = red, %Colour of internal links
  citecolor   = red %Colour of citations
}

但这个不起作用，它关闭了方框，但将所有链接的颜色变为蓝色。我该如何让它起作用？

该课程确实

\AtBeginDocument{\@ifpackageloaded{hyperref}
  {\def\@linkcolor{blue}
   \def\@anchorcolor{blue}
   \def\@citecolor{blue}
   \def\@filecolor{blue}
   \def\@urlcolor{blue}
   \def\@menucolor{blue}
   \def\@pagecolor{blue}
\begingroup
  \@makeother\`%
  \@makeother\=%
  \edef\x{%
    \edef\noexpand\x{%
      \endgroup
      \noexpand\toks@{%
        \catcode 96=\noexpand\the\catcode`\noexpand\`\relax
        \catcode 61=\noexpand\the\catcode`\noexpand\=\relax
      }%
    }%
    \noexpand\x
  }%
\x
\@makeother\`
\@makeother\=
}{}}

所以你需要覆盖这个：

\documentclass{elsarticle}
\usepackage{hyperref}
\usepackage[hyperref]{xcolor}

\makeatletter
\hypersetup{colorlinks=true}
\AtBeginDocument{\@ifpackageloaded{hyperref}
  {\def\@linkcolor{red}
   \def\@anchorcolor{red}
   \def\@citecolor{red}
   \def\@filecolor{red}
   \def\@urlcolor{red}
   \def\@menucolor{red}
   \def\@pagecolor{red}
\begingroup
  \@makeother\`%
  \@makeother\=%
  \edef\x{%
    \edef\noexpand\x{%
      \endgroup
      \noexpand\toks@{%
        \catcode 96=\noexpand\the\catcode`\noexpand\`\relax
        \catcode 61=\noexpand\the\catcode`\noexpand\=\relax
      }%
    }%
    \noexpand\x
  }%
\x
\@makeother\`
\@makeother\=
}{}}
\makeatother

\begin{document}

\tableofcontents

\section{Test section}
\href{www.tex.stackexchange.com}{TeX.sx} \cite{test}

\begin{thebibliography}{9}
\bibitem{test} Author, Title, 2015
\end{thebibliography}

\end{document}

或者更短，colorlinks=true在序言中做并改变颜色

\hypersetup{
  linkcolor=red,
  urlcolor=red,
  citecolor=red
}

在文档正文中：

\documentclass{elsarticle}
\usepackage{hyperref}
\usepackage[hyperref]{xcolor}

\hypersetup{
  colorlinks=true,
}

\begin{document}
\hypersetup{
  linkcolor=red,
  urlcolor=red,
  citecolor=red
}
\tableofcontents

\section{Test section}
\href{www.tex.stackexchange.com}{TeX.sx} \cite{test}

\begin{thebibliography}{9}
\bibitem{test} Author, Title, 2015
\end{thebibliography}

\end{document}

结果显示红色链接：
