所以我希望像MathJax一样使用KaTeX内联公式.
但到目前为止,我发现只有render()一个"绘制"字符串到元素的函数.
我需要修改DOM中文本节点的一部分.
我真的找不到如何用KaTeX做到这一点.它有这样的功能吗？
MathJax可以做到这一点.

是的,您可以$使用KaTeX的自动渲染扩展来内联所有定界公式.每个页面上的文档,$是不是默认的分隔符的一个,所以你需要设置它,当你调用renderMathInElement()和设置display到false,这使得在线.下面是一个例子,KaTeX的另一个例子可以在这里找到.
请注意,\\在JavaScript中对应\于HTML.

截至 2020 年初，KaTeX 0.11.1 似乎支持内联数学，而无需使用 Vincent 答案中的“hack”。单美元分隔符$ ... $不起作用，但转义括号\( ... \)起作用，如以下最小代码和片段所示：

经过一些测试，我无法使美元分隔符$ ... $起作用，但这里的括号\( ... \)默认工作是对 KaTeX 0.7.1 版本的更新（无论如何仍然可用）。
