Question

我有

的基本MathJax代码

<script type="text/javascript">
    MathJax.Hub.Config({
    extensions: ["tex2jax.js", "TeX/AMSmath.js"],
    jax: ["input/TeX", "output/SVG"],
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-MML-AM_CHTML"></script>
<div>$$a = b + c$$</div>

我希望公式应该替换为SVG代码，但结果与HTML输出相同，MathML代码：

<div>
    <span class="MathJax_Preview" style="color: inherit; display: none;"></span>
    <span class="mjx-chtml MJXc-display" style="text-align: center;">

如何将输出作为SVG矢量元素？

Answer 1

MathJax配置脚本的类型应为text/x-mathjax-config而不是text/javascript。此外，?config=TeX-MML-AM_CHTML似乎以某种方式凌驾于output/SVG。我用了?config=default。您可以获得有关配置文件here

<script type="text/x-mathjax-config">
    MathJax.Hub.Config({
        extensions: ["tex2jax.js", "TeX/AMSmath.js"],
        jax: ["input/TeX", "output/SVG"],
    })
</script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=default"></script>
<div>$$a = b + c$$</div>

＆＃13;

Answer 2

如果有人仍在使用MathJax 2.7.x，则修改config参数将在初始加载时渲染svg。

因此将TeX-AMS_CHTML更改为TeX-AMS_SVG

或将TeX-MML-AM_CHTML更改为TeX-MML-AM_SVG

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-AMS_SVG"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js?config=TeX-MML-AM_SVG"></script>
