问题
I am using MediaWiki with MathJax, because a lot of the pages have maths equations. But on some pages I also need to display the string $x$ as is.
Is there any way to escape the $x$ so it doesn't invoke MathJax and display as an italic x?
MathJax supports \$ to escape a $ within an expression, but that doesn't work with the initial $ (of course).
回答1:
If you set processEscapes:true in the tex2jax section of your configuration, then you will be able to escape the initial dollar sign to allow you to type $x$. Alternatively, you can use <span class="tex2jax_ignore">...</span> around the text you don't want MathJax to process. Perhaps easier would be to use <code>...</code> around the $x$, since MathJax doesn't process text inside code blocks.
