我正在开发一个基于代码的聊天组件。每次聊天都是一些代码片段。对于用户输入,我使用 monaco-editor

highlight.js 还有摩纳哥?

我也有同样的问题,所以我创建了一个问题#1171:

https://github.com/Microsoft/monaco-editor/issues/1171

提供了两种解决方案:

monaco.editor.colorizeElement(document.getElementById("yourElement"));

b) 格式化不属于任何元素的文本。这是一种更通用的方法,它返回一个承诺:

const code = "source code";
monaco.editor.colorize(code, "javascript")
  .then(html => document.getElementById("yourElement").innerHTML = html);

文档:

如果有人还在搜索,那么目前Monaco编辑器有一个声明性语法高亮显示,名为 Monarch
