我正尝试将章节编号放在奇数页的框中。每个偶数页上都有章节编号的方框很有帮助。但我正试图将方框移到奇数页。我尝试了几种方法，但都没有成功。

此代码只适用于偶数页。我想将框移到奇数页。如能提供一些意见，我们将不胜感激。提前致谢。
答案1
使用构造
\ifodd\value{page} % is value of page odd then do
% code to be executed for odd page
\else
% code to be executed for even pages
\fi
你可以定义要做什么。我理解你的问题，你想要盒子仅有的在奇数页上。因此你需要的代码如下：
\ifodd\value{page}
\makebox[\paperwidth][r]{%
\raisebox{\dimexpr.5\paperheight-.5\height}{%
\setlength{\fboxsep}{\baselineskip}%
\colorbox{chapterthumbbg}{\textcolor{white}{\thechapter}}%
}%
}%
\fi
使用以下 MWE
\documentclass{report}
\usepackage{lipsum}
\usepackage{eso-pic,xcolor}
\definecolor{chapterthumbbg}{HTML}{6F7175}
\AddToShipoutPictureFG{%
\AtPageLowerLeft{%
\ifshowchapterthumb\ifodd\value{page} % <=================================
\makebox[\paperwidth][r]{%
\raisebox{\dimexpr.5\paperheight-.5\height}{%
\setlength{\fboxsep}{\baselineskip}%
\colorbox{chapterthumbbg}{\textcolor{white}{\thechapter}}%
}%
}%
\fi\fi
}
}

\chapter{Second chapter}\lipsum[1-5]

\chapter{Third chapter}\lipsum[1-5]

\section{Second section}\lipsum[11-15]
\section{Third section}\lipsum[16-20]
\section{Last section}\lipsum[21-25]
\end{document}
你只会在奇数页上看到章节的方框，例如：
如果您想要在偶数页和奇数页上使用框，只需使用（只需删除包含\ifodd和 的行\fi）：
\makebox[\paperwidth][r]{%
\raisebox{\dimexpr.5\paperheight-.5\height}{%
\setlength{\fboxsep}{\baselineskip}%
\colorbox{chapterthumbbg}{\textcolor{white}{\thechapter}}%
}%
}%
由此得出的 MWE
\documentclass{report}
\usepackage{lipsum}
\usepackage{eso-pic,xcolor}
\definecolor{chapterthumbbg}{HTML}{6F7175}
\AddToShipoutPictureFG{%
\AtPageLowerLeft{%

你可以得到带有方框的偶数页和奇数页：
