添加脚本标签到React/JSX

我有一个相对简单的问题，试图将内联脚本添加到React组件。到目前为止我有:

'use strict';

import '../../styles/pages/people.scss';

import React, { Component } from 'react';
import DocumentTitle from 'react-document-title';

import { prefix } from '../../core/util';

export default class extends Component {
    render() {
        return (
            <DocumentTitle title="People">
                <article className={[prefix('people'), prefix('people', 'index')].join(' ')}>
                    <h1 className="tk-brandon-grotesque">People</h1>
                    
                    <script src="https://use.typekit.net/foobar.js"></script>
                    <script dangerouslySetInnerHTML={{__html: 'try{Typekit.load({ async: true });}catch(e){}'}}></script>
                </article>
            </DocumentTitle>
        );
    }
};

我也试过:

<script src="https://use.typekit.net/foobar.js"></script>
<script>try{Typekit.load({ async: true });}catch(e){}</script>

这两种方法似乎都不能执行所需的脚本。我猜我错过了一件简单的事。有人能帮忙吗?

PS:忽略foobar，我有一个真正的id实际上在使用，我不想分享。

当前回答

componentDidMount() {
  const head = document.querySelector("head");
  const script = document.createElement("script");
  script.setAttribute(
    "src",
    "https://assets.calendly.com/assets/external/widget.js"
  );
  head.appendChild(script);
}

我看到了同样的问题，直到我发现这个包，很容易实现，我希望它能像它为我工作:)

https://github.com/gumgum/react-script-tag

import React from 'react';
import Script from '@gumgum/react-script-tag';

import './App.css';

function App() {
  return (
    <div >

      <h1> Graphs</h1>
      <div class="flourish-embed flourish-network" data-src="visualisation/8262420">
        <Script  src"your script"
        </Script>
      </div>
    </div>
  );
}

export default App;

对于多个脚本，使用这个

var loadScript = function(src) {
  var tag = document.createElement('script');
  tag.async = false;
  tag.src = src;
  document.getElementsByTagName('body').appendChild(tag);
}
loadScript('//cdnjs.com/some/library.js')
loadScript('//cdnjs.com/some/other/library.js')

根据Alex McMillan的解决方案，我有如下的调整。我自己的环境:React 16.8+，下一个v9+

//添加一个名为Script的自定义组件 / / / Script.js hook

import { useEffect } from 'react'


// react-helmet don't guarantee the scripts execution order
export default function Script(props) {

  // Ruels: alwasy use effect at the top level and from React Functions
  useEffect(() => {
    const script = document.createElement('script')

    // src, async, onload
    Object.assign(script, props)

    let { parent='body' } = props

    let parentNode = document.querySelector(parent)
    parentNode.appendChild(script)

    return () => {
      parentNode.removeChild(script)
    }
  } )

  return null  // Return null is necessary for the moment.
}

//使用自定义组件，只需导入它，并将旧的小写<script>标记替换为自定义驼色大小写<script>标记就足够了。 / / index.js

import Script from "../hooks/Script";
    
<Fragment>
  {/* Google Map */}
  <div ref={el => this.el = el} className="gmap"></div>

  {/* Old html script */}
  {/*<script type="text/javascript" src="http://maps.google.com/maps/api/js"></script>*/}

  {/* new custom Script component */}
  <Script async={false} type="text/javascript" src='http://maps.google.com/maps/api/js' />
</Fragment>

你也可以使用反应头盔

import React from "react";
import {Helmet} from "react-helmet";

class Application extends React.Component {
  render () {
    return (
        <div className="application">
            <Helmet>
                <meta charSet="utf-8" />
                <title>My Title</title>
                <link rel="canonical" href="http://example.com/example" />
                <script src="/path/to/resource.js" type="text/javascript" />
            </Helmet>
            ...
        </div>
    );
  }
};

Helmet接受普通HTML标记并输出普通HTML标记。这是非常简单的，React初学者友好。

你可以使用npm postscribe在react组件中加载脚本

postscribe('#mydiv', '<script src="https://use.typekit.net/foobar.js"></script>')
