How to use hyperref mailto: together with new command

Question

Background:

So basically, I would like to have a hyperlink to an email address. That email address, however, should not be fixed at the moment. It should be changeable.

So I tried to achieve that by defining the email as a new command, and then use it inside hyperref command.

But it doesn't seem to work. Latex gave me an error: undefined control sequence.

\documentclass{article}
\usepackage{hyperref}
\hypersetup{colorlinks=true, linkcolor=red}
\newcommand{\emailaddress}{jxhyctc@163.com}
\begin{document}

\href{mailto:\emailaddress}{\emailadrress}


\end{document}

Any help is greatly appreciated.

Answer 1

Check your spelling :)

\documentclass{article}
\usepackage{graphicx}
\usepackage{hyperref}
\usepackage{tikz}
\hypersetup{colorlinks=true, linkcolor=red}

\newcommand{\emailaddress}{jxhyctc@163.com}
\begin{document}

\href{mailto:\emailaddress}{\emailaddress} % 'address', not 'adrress'


\end{document}
