@GXDXK 右键 -> 检查元素，打开开发者工具看看 <code> 的类名，识别成什么语言了

[GXDXK]

以SQL Server 2008 R2的高亮为例
识别成了hljs language-stylus
但请问

为什么在没有指定语言的情况下仍然有高亮？
如果我不需要高亮效果，该如何编写markdown呢？

[jyxjjj]

第一行反引号后面加plain

[GXDXK]

@jyxjjj 没有作用

[jyxjjj]

@xrgzs 感觉是默认规则问题

是不是把

hljs.highlightAll();

改成

document.querySelectorAll('pre code').forEach(el => {
  hljs.highlightElement(el);
});

或者直接禁止自动检测？

[jyxjjj]

当我没说 这个language-scss应该是remarkRehype生成的
也可能是remarkRehype生成后被hljs认为不支持于是又改成scss

code: [
  ["className", /^language-[\w-]+$/, ...]
]

是不是应该

markdownRef()
  ?.querySelectorAll("pre code[class^='language-']:not(.language-plain)")
  .forEach((el) => {
    hljs.highlightElement(el as HTMLElement)
  })

我的也是升级后 md 内嵌的前端 html 和 css 代码不能识别为正常 ui 了，一堆乱码，4.1.10 版本是正常的，4.2.0 和 2.1 都有问题，升级后又降级回来了

PR submitted: OpenListTeam/OpenList-Frontend#559 (approved, pending merge)

Root cause: hljs.highlightAll() applies auto-detection to all <pre><code> blocks, including those without a language-* class generated from markdown code fences with no language specified.

Fix: Replaced with selective highlightElement() — only target code blocks that have an explicit language-* class, skip language-plain / language-plaintext / language-text.

Tested with the exact examples from this issue (keys, registrations, configs) in a local deployment — no more random highlighting on plain code blocks.
