仅使用 hyperref 将章节标题链接到目录

仅使用 hyperref 将章节标题链接到目录

如何将章节标题链接回目录？我想使用仅有的 hyperref并且没有任何与 toc 相关的包（答案是titlesec可以找到答案这里）

我可以做hypertargetto c 部分（回答由 cmhughes 提供，并在下面的 MWE 中显示）。因此，我的问题实际上是：把这条hyperlink线放在哪里？

\documentclass{report}
\usepackage{hyperref}

\let\oldcontentsline\contentsline%
\renewcommand\contentsline[4]{%
\hypertarget{toc#4}{}%
\oldcontentsline{#1}{#2}{#3}{#4}}

\begin{document}
\tableofcontents
\chapter{A Chapter to act as a Link}
\section{A Section to act as a Link}
\end{document}

不确定这是否是你想要的

\documentclass{report}
\usepackage[colorlinks]{hyperref}

\let\oldcontentsline\contentsline%
\renewcommand\contentsline[4]{%
    \oldcontentsline{#1}{\smash{\raisebox{1em}{\hypertarget{toc#4}{}}}#2}{#3}{#4}}
\newcommand\mychapter[1]{%
    \chapter[#1]{\protect\hyperlink{tocchapter.\thechapter}{#1}}}
\newcommand\mysection[1]{%
    \section[#1]{\protect\hyperlink{tocsection.\thesection}{#1}}}
\newcommand\mysubsection[1]{%
    \subsection[#1]{\protect\hyperlink{tocsubsection.\thesubsection}{#1}}}

\begin{document}
    \tableofcontents
    \mychapter{A Chapter to act as a Link}
        \mysection{A Section to act as a Link}
            \mysubsection{A Subection to act as a Link}
            \mysubsection{A Subection to act as a Link}
        \mysection{A Section to act as a Link}
            \mysubsection{A Subection to act as a Link}
            \mysubsection{A Subection to act as a Link}
    \mychapter{A Chapter to act as a Link}
        \mysection{A Section to act as a Link}
            \mysubsection{A Subection to act as a Link}
            \mysubsection{A Subection to act as a Link}
        \mysection{A Section to act as a Link}
            \mysubsection{A Subection to act as a Link}
            \mysubsection{A Subection to act as a Link}
    \clearpage~
\end{document}

理想情况下，人们只需使用\apptocmd命令（来自etoolbox包）或\xapptocmd（来自xpatch包）来挂钩适当的超目标/超链接命令，但不幸的是，由于结构命令的定义（例如\part，\chapter等等） ，这会中断。

但是，对这些命令进行通用的“轻微”重新定义可以实现这一点。首先，使用通用结构化命令，在文档的开头，循环（七个）命令定义这些命令并添加链接。否则，这些命令将按照其原始定义运行（因此，\LaTeXStandardpart必须通过循环和使用\csletcs命令来定义等）。

\documentclass{book}

\usepackage{etoolbox}%
\usepackage[final,pdftex]{hyperref}%

\listgadd{\StructureCommandsList}{}%


\newcommand{\LetLaTeXStandardSectionCommand}[1]{%
  \csletcs{LaTeXStandard#1}{#1}%
}%

\makeatletter%

\apptocmd{\tableofcontents}{\phantomsection\hypertarget{document::toc}{}}{}{}%

\newcommand{\redefinestructurecommands}[1]{%
  \csgdef{unstarred#1@@noopt}##1{%
    \csuse{unstarred#1@@opt}[##1]{##1}%
  }%

  \csgdef{unstarred#1@@opt}[##1]##2{%
    \csuse{LaTeXStandard#1}[##1]{\hyperlink{document::toc}{##2}}%
  }%


  \csgdef{unstarred#1}{%
    \@ifnextchar[{%
      \@nameuse{unstarred#1@@opt}%
    }{%
      \@nameuse{unstarred#1@@noopt}%
    }%
  }%

  \csgdef{starred#1@@noopt}##1{%
    \csuse{LaTeXStandard#1}*{\hyperlink{document::toc}{##1}}%
  }%


  \csgdef{unstarred#1}{%
    \@ifnextchar[{%
      \csuse{unstarred#1@@opt}%
    }{%
      \csuse{unstarred#1@@noopt}%
    }%
  }%

  \csgdef{#1}{%
    \@ifstar{%
      \csuse{starred#1@@noopt}%
    }{%
      \csuse{unstarred#1}%
    }%
  }%
}%

\makeatother


\newcommand{\RedefineStructuringCommands}{%
   % If some of the structuring commands should not use linking back to toc, just remove them from this csv - list here (say for subparagraph))
  \forcsvlist{\listgadd{\StructureCommandsList}}{part,chapter,section,subsection,subsubsection,paragraph,subparagraph}%
  \forlistloop{\LetLaTeXStandardSectionCommand}{\StructureCommandsList}%
  \forlistloop{\redefinestructurecommands}{\StructureCommandsList}%
}%


\AtBeginDocument{%
  \RedefineStructuringCommands%
}%


\setcounter{secnumdepth}{5}% For demo only
\setcounter{tocdepth}{5}% For demo only

\begin{document}
\chapter*{Introduction}%

\tableofcontents%

\part{First part}%
\chapter{First chapter}%
\section{First Section}%
\section*{First starred section}%
\subsection{First subsection}%
\subsubsection{First subsubsection}%
\paragraph{First paragraph}
\subparagraph{First subparagraph}%

\end{document}

我省略了屏幕截图，因为它实际上没有显示任何内容。

笔记：上述重新定义命令\redefinestructurecommand是尚未发布的包的一部分，它通常更长且更复杂;-)

我想这就是我所追求的。感谢 Symbol 1 提出的想法！

\documentclass{report}
\usepackage{hyperref}

\let\oldcontentsline\contentsline%
\renewcommand\contentsline[4]{%
\hypertarget{toc#4}{}%
\oldcontentsline{#1}{#2}{#3}{#4}}
\let\oldsection\section
\renewcommand\section[1]{%
    \oldsection[#1]{\protect\hyperlink{tocsection.\thesection}{#1}}}

\begin{document}
\tableofcontents
\chapter{A Chapter to act as a Link}
\section{A Section to act as a Link}
\end{document}
