我使用innerHTML一起引用span:

import React, { useRef, useEffect, useState } from 'react';

export default function Sample() {
  const spanRef = useRef<HTMLSpanElement>(null);
  const [someHTML,] = useState("some <b>bold</b>");

  useEffect(() => {
    if (spanRef.current) {
      spanRef.current.innerHTML = someHTML;
    }
  }, [spanRef.current, someHTML]);

  return <div>
    my custom text follows<br />
    <span ref={spanRef} />
  </div>
}

更新:

我删除了一些html状态，并添加了注释，以使示例更符合概念。

/**
 * example how to retrieve a reference to an html object
 */

import React, { useRef, useEffect } from 'react';

/**
 * this component can be used into another for example <Sample/>
 */
export default function Sample() {
    /**
     * 1) spanRef is now a React.RefObject<HTMLSpanElement>
     * initially created with null value
     */
    const spanRef = useRef<HTMLSpanElement>(null);

    /**
     * 2) later, when spanRef changes because html span element with ref attribute,
     * follow useEffect hook will triggered because of dependent [spanRef].
     * in an if ( spanRef.current ) that states if spanRef assigned to valid html obj
     * we do what we need : in this case through current.innerHTML
     */
    useEffect(() => {
        if (spanRef.current) {
            spanRef.current.innerHTML = "some <b>bold</b>";
        }
    }, [spanRef]);

    return <div>
        my custom text follows<br />
        {/* ref={spanRef] will update the React.RefObject `spanRef` when html obj ready */}
        <span ref={spanRef} />
    </div>
}

我使用" react-html-parser "

yarn add react-html-parser

import ReactHtmlParser from 'react-html-parser'; 

<div> { ReactHtmlParser (html_string) } </div>

提升@okram的评论以提高能见度:

从它的github描述:转换HTML字符串直接到React 组件避免使用危险的setinnerhtml 一个将HTML字符串转换为React组件的实用程序。 避免使用dangerlysetinnerhtml并转换标准HTML 元素，属性和内联样式到它们的React等价物中。

我使用https://www.npmjs.com/package/html-to-react

const HtmlToReactParser = require('html-to-react').Parser;
let htmlInput = html.template;
let htmlToReactParser = new HtmlToReactParser();
let reactElement = htmlToReactParser.parse(htmlInput); 
return(<div>{reactElement}</div>)

你只是使用了React的dangerlysetinnerhtml方法

<div dangerouslySetInnerHTML={{\ __html: htmlsthtml} />

或者你可以用这个简单的方法实现更多:在React应用程序中渲染HTML原始

如果你可以控制包含html的字符串从哪里来(即。)，你可以从新的<Fragment> API中受益，做一些像这样的事情:

import React, {Fragment} from 'react'

const stringsSomeWithHtml = {
  testOne: (
    <Fragment>
      Some text <strong>wrapped with strong</strong>
    </Fragment>
  ),
  testTwo: `This is just a plain string, but it'll print fine too`,
}

...

render() {
  return <div>{stringsSomeWithHtml[prop.key]}</div>
}

检查你试图附加到节点的文本是否没有像这样转义:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

而不是这样:

var prop = {
    match: {
        description: '<h1>Hi there!</h1>'
    }
};

如果转义，您应该从服务器端转换它。

节点为文本，因为已转义

该节点是dom节点，因为没有转义
