新的 mathjax windows

Question

我有一个玩 MathJax 的测试代码，它显示一些编号和可参考的数学方程式，以及一个按钮，旨在用相同的数学在浏览器中打开一个新的 windows内容...

In equation \eqref{eq:sample}, we find the value of an
interesting integral:

\begin{equation}
  \int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
  \label{eq:sample}
\end{equation}
<h1>A test of Equation References</h1>

<hr>
Here is a labeled equation:

\begin{equation}x+1\over\sqrt{1-x^2}\label{ref1}\end{equation}
with a reference to ref1: \ref{ref1},
and another numbered one with no label:
$$x+1\over\sqrt{1-x^2}$$
This one uses \nonumber:
$$x+1\over\sqrt{1-x^2}\nonumber$$
<hr>
Here's one using the equation environment:
\begin{equation}
x+1\over\sqrt{1-x^2}
\end{equation}
and one with equation* environment:
\begin{equation*}
x+1\over\sqrt{1-x^2}
\end{equation*}

但是新页面中的数学内容不会在页面加载时呈现，关于如何修复它的任何线索？主标签和新标签 windows 中的 <head> 标签相同 ...

提前致谢

Answer 1

您已将整个 MathJax 配置放在一行中，但在其中留下了评论：

//automatic eqn numbering !!! } }); </scr'+'ipt>

这导致最后的 }}); 被注释掉，这反过来又破坏了配置（它现在无效 JavaScript）。

只需删除 //automatic eqn numbering !!!

如果您打开开发人员控制台，您会发现一条错误消息，这将是一个很好的调试起点。
