Natbib 脚注引文

基于@moewe 提供的有益建议这里和这里，我想寻求帮助，以便获得更复杂的脚注引用命令，让用户也能包含页码。长话短说，我正在帮助一位同事完成一个使用 natbib 的旧项目。

最小工作示例如下，

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{A01,
    author = {Author Name},
    publisher = {Publisher Co.},
    title = {Title of the Book},
    year = {2022}}
\end{filecontents}
\listfiles 

\documentclass{article} 
\usepackage{natbib}

\begin{document}

\NewDocumentCommand{\footcite}{om}{\footnote{\IfNoValueTF{#1}{\cite{#2}}{\cite[#1]{#2}}}}

Test function of footnote citation without page number.\footcite{A01}

Test function of footnote citation with page number.\footcite[2]{A01}

\bibliographystyle{plainnat} 
\bibliography{\jobname}

\end{document}

不幸的是，该命令\NewDocumentCommand{\footcite}{om}{\footnote{\IfNoValueTF{#1}{\cite{#2}}{\cite[#1]{#2}}}}导致未定义的控制序列错误。

非常感谢任何指导或建议！

经过一番尝试，我终于搞明白了！请参阅现在具有所需输出的功能性 MWE。另请注意，我添加了一些样式选项。我希望这对有类似需求的未来用户有所帮助！

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{A01,
    author = {Author Name},
    publisher = {Publisher Co.},
    title = {Title of the Book},
    year = {2022}}
\end{filecontents}
\listfiles 

\documentclass{article} 
\usepackage{natbib}
\setcitestyle{authoryear,open={(},close={)}} %Citation-related command, replaces default brackets to parentheses 
\setcitestyle{aysep={}} %Citation-related command, removes default comma between author & year

\usepackage{xparse}
\NewDocumentCommand\footcite{o m}
{%
\footnote{ %
\IfNoValueTF {#1}%
{\citet{#2}}%
{\citet[#1]{#2}}%
}
}

\begin{document}

Test function of footnote citation without page number.\footcite{A01}

Test function of footnote citation with page number.\footcite[2]{A01}

\bibliographystyle{plainnat} 
\bibliography{\jobname}

\end{document}
