交叉引用目录中的超链接和分页符

Question

TOC 参赛作品要求如下：

1. （2）和（3）定义的目录分页符应该是自动的（无需手动添加，\addtocontents{toc}{\protect\newpage}如将目录拆分为两页）
2. 级别与子级别之间应禁止中断。
3. 只要满足（2），某个级别就应该具有最少的中断次数，并且更深的级别具有最高的优先级，即：
   • (3.1) 只要满足 (2)，如果某个级别无法在少于 (N+1) 个页面且不存在 Overfull \vbox，则该级别就会出现 N 个中断。
   • （3.2）（最大深度）水平突破无论如何都是没有意义的。
   • （3.3）对于X范围从（最大深度-1）到（最小深度），X深度级别不可避免的中断是：
   • • （3.3.1）与（2）不冲突。
   • • （3.3.2）在不会向更深层次添加任何断点的行上。
   • • （3.3.3）位于最低行，以防止 \vbox 过满。
   • （3.4）“内容”与下列项目之间没有间隔，因为这与（2）相冲突。
4. 级别标题和目录之间的交叉引用应该准确。

问题是 ：

• 条件 (3.1) 和 (3.3.2) 不起作用，因为它应该在 (第 1.32 节) 和 (第 2 部分) 之前破坏目录页面。
• 条件 (4) 从章节标题到目录条目不起作用，因为您始终会被引导至第一个子级目录条目。
• 如果未手动添加，则条件 (4) 不适用于从其他级别标题到目录条目（请参阅小节 1.32.2）\addtocontents{toc}{\protect\newpage}。

该\titleformat{\chapter}命令放在\begin{document}“内容”之后是为了不让其成为死链接。

事实上，这个链接在这里根本就不起作用，因为 (4) 对章节标题不起作用。

无论如何，放置\titleformat{\chapter}在序言中都无法解决问题。

我已经尝试\Hy@raisedlink了从超链接导航到超链接超目标后的垂直位置似乎太低

结果可能是由于连字符引起的错误，如下所述`\Hy@raisedlink` 阻止连字并干扰换行

对于章节，问题似乎是由于.toc文件的写入方式造成的，因为\hypertarget {\the part.\thechapter}{}应该在相应的之前写入\contentsline（.toc下面给出代码）。

在此先感谢您的帮助。

PS：不确定这个工作示例是否真的很简单，因为我还加载了可能会干扰标题的额外包，即：

• chngcntr如上所述使用 \part 时超链接不正确。我该如何纠正？
• fancyhdr如上所述fancyhdr：如何将部分内容放在偶数页，将章节放在奇数页

这是 .tex 文件：

Answer 1

关键是要修改以在同一行上\contentsline添加。在某些环境（如表格）中，瞄准太低一行是一个已知问题，可以使用或修复。请参阅\hypertarget\hypertarget\raisebox\vadjust pre{...}这个问题。

注意：hyperref 修改\addtocontents并\contentsline包含超目标名称。我只是将.cross这个名称添加到交叉引用中。
