【问题描述】：
在我的应用程序中配置 Mathjax v.3 时，我有一个带有三个选项的探针。反映问题的最少代码是一个 html 文件和两个 js 文件，一个是从 github 下载的 tex-svg.js，另一个是我的 mathjax 配置文件。 读取 HTML 文件的内容
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>title</title>
<script type="text/javascript" src="test_files/mathjax-config.js"></script>
<script type="text/javascript" src="test_files/tex-svg.js" async=""></script>
</head>
<body>
first we have $1+\tan(\alpha)^2=\frac{1}{\cos(x)^2}$, then we have $$\int_a^b f(x,\tau,\epsilon)\,dx$$ and last we would have<br>\begin{align}<br>\sin(x)<br>\end{align}<br>and then continue by going to the next line ...<br>... right here
</body>
</html>
配置文件内容如下
window.MathJax = {
options: {
renderActions: {
addMenu: [],
//checkLoading: []
}
},
loader: {
//load: ['[tex]/tagFormat']
},
tex: {
inlineMath: [ ["$","$"] ], // ["$","$"],["\$","\$"],["\(","\)"],["\\(","\\)"]
displayMath: [ ["$$","$$"] ],
processEscapes: true, // for \$ to mean a common dollar sign, not a math delimiter
//ignoreHtmlClass: 'tex2jax_ignore', // divs with class "tex2jax_ignore" are NOT to be rendered
//processHtmlClass: 'tex2jax_process' // divs with class "tex2jax_process" are to be rendered
//processEnvironments: true, // process \begin{xxx}...\end{xxx} outside math mode
//processRefs: true, // process \ref{...} outside of math mode
packages: {'[+]': ['tagFormat','includeHtmlTags','skipTags']},
skipTags: ["script", "style", "textarea", "pre", "code"], //their contents won't be scanned for math
includeHtmlTags: {br: '\n', wbr: '', '#comment': ''}, // HTML tags that can appear within math
digits: /^(?:[\d۰-۹]+(?:[,٬'][\d۰-۹]{3})*(?:[\.\/٫][\d۰-۹]*)?|[\.\/٫][\d۰-۹]+)/, // introduce numbers
tagSide: "right",
tagIndent: ".8em",
multlineWidth: "85%",
tags: "ams",
tagFormat: {
number: function(n){
return n.replace(/0/g,"۰").replace(/1/g,"۱").replace(/2/g,"۲").replace(/3/g,"۳")
.replace(/4/g,"۴").replace(/5/g,"۵").replace(/6/g,"۶").replace(/7/g,"۷")
.replace(/8/g,"۸").replace(/9/g,"۹");
}
}
},
svg: {
fontCache: 'global', // or 'local' or 'none'
mtextInheritFont: true, // required to correctly render RTL Persian text inside a formula
scale: 0.97, // global scaling factor for all expressions
minScale: 0.6 // smallest scaling factor to use
//matchFontHeight: true, // true to match ex-height of surrounding font
//exFactor: .5, // default size of ex in em units
//displayAlign: 'center', // default for indentalign when set to 'auto'
//displayIndent: '0' // default for indentshift when set to 'auto'
},
chtml: {
mtextInheritFont: true, // required to correctly render RTL Persian text inside a formula
scale: 0.97, // global scaling factor for all expressions
minScale: 0.6 // smallest scaling factor to use
//matchFontHeight: true, // true to match ex-height of surrounding font
//exFactor: .5, // default size of ex in em units
//displayAlign: 'center', // default for indentalign when set to 'auto'
//displayIndent: '0', // default for indentshift when set to 'auto'
//adaptiveCSS: true // true means only produce CSS that is used in the processed equations
}
};
问题在于这些选项：
skipTags、includeHtmlTags 和 tagFormat
我使用的任何一个，都会在控制台中写入一个错误，上面写着 Invalid option 因为没有默认值。据我所知，这个错误表明这些没有加载，但我不知道该怎么做。添加 load: ['[tex]/tagFormat'] 之类的代码在找不到特定地址的 js 文件时会出现另一个错误，而 MathJax3 似乎应该是单文件解决方案。
我哪里错了？解决方案是什么？ 提前致谢
