math/tex Custom Script Type Extension

This is an extension to automatically display code inside script tags with type=math/tex using KaTeX. This script type is commonly used by MathJax, so this can be used to support compatibility with MathJax.

Usage

This extension isn't part of KaTeX proper, so the script should be separately included in the page, in addition to KaTeX.

Load the extension by adding the following line to your HTML file. This extension should be loaded after all script type=math/tex blocks that you want to render.

<script src="https://cdn.jsdelivr.net/npm/katex@0.10.0/dist/contrib/mathtex-script-type.min.js" integrity="sha384-zWYbd0NBwgTsgIdFKVprSfTh1mbMPe5Hz1X3yY4Sd1h/K1cQoUe36OGwAGz/PcDy"></script>

You can download the script and use it locally, or from a local KaTeX installation instead.

For example, in the following simple page, we first load KaTeX as usual. Then, in the body, we use a math/tex script to typeset the equation x+\sqrt{1-x^2}. After we're done writing math/tex scripts, we load this extension.
