Some type cant display correctly

[majiayu000]

Some latex like $12 - \frac{7}{11}$.

If put this in mathjax, this can display, but cant here.

I think you're just forgetting about escape characters in Javascript strings. When you want to output a \ you have to add \\ inside a string.

[majiayu000]

Seems not a \ question.

Have you added $ as a delimiter in your config? At least you're no longer getting Math input error so you also had a problem with escaping it seems. $ is not a default MathJax delimiter so you have to specify it. Try using $$. If that works, then you need to specify $ as a delimiter as well.

Thanks for your patients. After I using config, it worked. I did not see these configs.

No problem :) Feel free to close this ticket if the problem is solved :)

\frac{1}{2} I meet another question. How can just display a latex without any \\ or (.

Thank you!

You can't. MathJax operates on delimiters. You can use manual typesetting and provide the string you want to typeset like

          <MathJax
            renderMode={"pre"}
            typesettingOptions={{ fn: "tex2chtml" }}
            text={`x^4 = 100`}
          />

but I wouldn't recommend that.

Ok, so the question is to discover the latex string. I will try, thank you again!
