// For typescript import parse, { HTMLReactParserOptions } from "html-react-parser"; import { Element } from "domhandler/lib/node"; export function contentHandler(postContent: string) { const options: HTMLReactParserOptions = { replace: (domNode: Element) => { if (domNode.attribs) { if (domNode.attribs.id === 'shortcode') { return <div className="leadform">Shortcode</div>; } } }, }; return parse(postContent, options); } // Usage: contentHandler("<span>Hello World!</span>")

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>
}

如果您可以控制{this.props.match.description}，并且您正在使用JSX。我建议不要使用“dangerlysetinnerhtml”。

// In JSX, you can define a html object rather than a string to contain raw HTML
let description = <h1>Hi there!</h1>;

// Here is how you print
return (
    {description}
);

你也可以使用跳线包中的parseReactHTMLComponent。看一下就知道，它很简单，不需要使用JSX语法。

如果你在字符串中有HTML，我建议使用一个叫做HTML -react-parser的包。

安装

NPM:

npm install html-react-parser

纱:

yarn add html-react-parser

使用

import parse from 'html-react-parser'
const yourHtmlString = '<h1>Hello</h1>'

代码:

<div>
    {parse(yourHtmlString)}
</div>

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>)
