how to call custome js function after katex complete it's job?

You can just call the function after calling renderMathInElement (assuming you're calling that), as it's synchronous.

[Rss-Imran]

suppose
p id="body" style="visibility:hidden;">
$$ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $$
p

after finish katex rendering how to call
document.getElementById("body").style.visibility="visible";
could i have an example about it?

[edemaine]

Something like this?

renderMathInElement(document.getElementById("body"));
document.getElementById("body").style.visibility="visible";

<script defer src="katex/contrib/auto-render.js" onload="renderMathInElement(document.body); document.getElementById('body').style.visibility='visible';"></script>

works for me.
