問題
這是“代碼 1”（將添加到上面“新代碼”部分的序言中）：
\fancypagestyle{chapterstart}{% 1st page of the chapters, i.e. no new page for chapter
}
\makeatletter
\def\chapter{
\pagestyle{chapterstart}
\secdef\@chapter\@schapter}
\renewcommand\thesection{\@arabic\c@section}
\makeatother
這段程式碼允許我在同一頁上開始一個新的章節，並且它也將我的頁首和頁腳保持在同一頁上。但是，這會重置每章的節號。例如，「第 2 章第 2.1 節」將改為「第 2 章第 1.1 節」。
這是“代碼 2”（與之前一樣在上面添加）：
\usepackage{etoolbox}
\makeatletter
\patchcmd{\chapter}{\if@openright\cleardoublepage\else\clearpage\fi}{}{}{}
\makeatother
此程式碼允許我在同一頁上開始一個章節，並保留分段的原始編號，例如「第 2 章，第 2.1 節」將保留為「第 2 章，第 2.1 節」。但是我的頁首和頁尾不會包含在同一頁上
目標
如何組合「代碼 1」和「代碼 2」以允許我：在同一頁上開始新章節，將頁首和頁尾保留在新章節頁面上，並保留章節編號的格式。
答案1
代碼 1 可以在沒有\renewcommand\thesection{\@arabic\c@section}.這裡省略了章節號（原文是\thechapter.\@arabic\c@section）。
但有一個缺點，它沒有設置\@afterindentfalse，這會導致普通文本的章節標題後面的第一段縮排。
該線\pagestyle{chapterstart}不是必需的。原\chapter套\thispagestyle{plain}。如果沒有這個，頁面樣式就不會改變。
在程式碼 2 中，\chapter使用 進行更改\patchcmd，其優點是，如果命令更改並且無法再進行修補，則可以發出警告或錯誤（最後一個參數，程式碼中的範例）。
