如何引用脚注？

Question

如何引用脚注？例如，如果构造如下

blah blah blah blah\footnote{blah blah \label{footnote_1}}

您会使用这句话来引用它吗？

As mentioned in note \ref{footnote_1}.

Answer 1

\documentclass{article}
\usepackage{footmisc}
\begin{document}

argument of the footnote command that is being 
labelled\footnote{Note text\label{fnlabel}}
potato head\footref{fnlabel}

\end{document}

Answer 2

它也适用于全能的cleveref（代替footmisc）：

\documentclass{article}
\usepackage{cleveref}
\begin{document}
Here is some real nondescript text\footnote{What a qualifier\label{xxx}}

Then I can refer later to \cref{xxx} (\Cpageref{xxx})
\end{document}
