博主本人自己改编的 hexo-theme-livemylife
主题,有小伙伴在用时,问我是否支持 Mathjax 数学公式,由于工作原因未能增加此功能,在此次的 hexo-theme-livemylife
主题升级中,博主对之前小伙伴们提出的问题做了一个统一的修复和升级。那么让我们来看看 Mathjax 在 hexo-theme-livemylife
主题中是如何应用的。
Mathjax: Beautiful and accessible math in all browsers.
A JavaScript display engine for mathematics that works in all browsers.
No more setup for readers. It just works.
上述是 Mathjax 官网原文解释。官网地址:https://www.mathjax.org/
安装渲染器
hexo 默认的渲染器是 marked,并不支持 mathjax。kramed 是在 marked 基础上修改的,支持了mathjax。在 hexo 工程目录下的 node_modules 中可以找到对应的渲染器文件夹。同时在你的工程目录下用以下命令安装 kramed。
1 | npm uninstall hexo-renderer-marked --save |
如果你安装了 hexo-math 包,卸载再安装 hexo-renderer-mathjax 包。
1 | npm uninstall hexo-math --save |
更新 mathjax 的 CDN,打开 node_modules/hexo-renderer-mathjax/mathjax.html
(可做可不做)。但是,我把 http 改成 https 了:
1 | <script src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script> |
改成:
1 | <script src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.6/MathJax.js?config=TeX-MML-AM_CHTML"></script> |
如果小伙伴你用的是博主本人写的 hexo-theme-livemylife
主题的话,那么上述步骤,博主本人已经帮你完成了。那接下来让我们一起看几个渲染后的 mathjax 案例:
Example1:
1 | When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are |
Preview:
When $a \ne 0$, there are two solutions to (ax^2 + bx + c = 0) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
Example2:
1 | $$f(x_1,x_2,\underbrace{\ldots}_{\rm ldots} ,x_n) = x_1^2 + x_2^2 + \underbrace{\cdots}_{\rm cdots} + x_n^2$$ |
Preview:
$$f(x_1,x_2,\underbrace{\ldots}{\rm ldots} ,x_n) = x_1^2 + x_2^2 + \underbrace{\cdots}{\rm cdots} + x_n^2$$
Example4:
1 | $$ |
Preview:
$$
\begin{bmatrix} 1&x&x^2\ 1&y&y^2\ 1&z&z^2 \end{bmatrix}
\
\begin{bmatrix} 1&x&x^2\\ 1&y&y^2\\ 1&z&z^2 \end{bmatrix}
\
vmatrix ||、Bmatrix{}、pmatrix()
$$
Example5:
1 | $$ |
Preview:
$$
f(x)=
\begin{cases}
0& \text{x=0}\\
1& \text{x!=0}
\end{cases}
$$
Example6:
1 | $$\lim_{n \rightarrow +\infty} \frac{1}{n(n+1)}$$ |
Preview:
$$\lim_{n \rightarrow +\infty} \frac{1}{n(n+1)}$$
