GitHub wiki 页面不再支持MathJax。似乎dotjs Chrome 扩展程序可能是在这些页面上启用 MathJax 的一种方式。
这是我第一次尝试创建将在 github.com 页面上执行的 javascript,并插入启用 MathJax 所需的正确代码:
[~]$ cat .js/github.com.js
(function () {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "https://c328740.ssl.cf1.rackcdn.com/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML";
document.getElementsByTagName("head")[0].appendChild(script);
})();
但是,这不起作用,并且 Chrome JavaScript 控制台中会出现以下错误:
Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self'
https://github.com https://a248.e.akamai.net https://jobs.github.com https://ssl.google-analytics.com https://secure.gaug.es https://collector.githubapp.com https://gist.github.com".
c328740.ssl.cf1.rackcdn.com/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML:29
什么是正确的 JavaScript?
