    document.addEventListener("DOMContentLoaded", function() {
        renderMathInElement(document.body, {
          // customised options
          // • auto-render specific keys, e.g.:
          delimiters: [
              {left: '$$', right: '$$', display: true},
              {left: '$', right: '$', display: false},
              {left: '\\(', right: '\\)', display: false},
              {left: '\\[', right: '\\]', display: true}
          ],
          // • rendering keys, e.g.:
          throwOnError : false
        });
    });
</script>

来自 https://katex.org/docs/autorender 可以自动渲染

在index.html 添加

<script>MathJax = {tex: {inlineMath: [['$', '$'],['$$', '$$'], ['\\(', '\\)']]}}</script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml.js"></script>

在vue中添加

nextTick(() => MathJax.typesetPromise())
