进口如何突出。 j 反应部分?
原标题:How to import highlight.js on react component?

我想展示和强调React.js部分中的一些“JSON”数据。

问题在于该部分复读时,突出的法典消失。

我想澄清一下,我在这里说了一个新东西。

感谢你的支持。

import React from "react";

import hljs from "highlight.js";
import "highlight.js/styles/github.css";
import json from "highlight.js/lib/languages/json";
hljs.registerLanguage("json", json);
hljs.initHighlightingOnLoad();

const JsonViewer = props => {
  return (
    <pre>
      <code className="json">
         {JSON.stringify(props.content, null, 2)}
      </code>
    </pre>
  );
};

export default JsonViewer;
问题回答

From what I see the function call hljs.initHighlightingOnLoad(); is the one activating the highlighting. If you are using hooks call that function in useEffect or if you are using classes call it in componentDidMount and componentDidUpdate.
