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。

以下是我如何最终能够在React JS代码中添加两个外部JavaScript文件:

以下是我遵循的步骤。

步骤1: 我在react-app文件夹路径中使用npm I React-Helmet从终端安装了React-Helmet。

步骤2: 然后我添加了import {Helmet} from "react-helmet";头在我的代码。

步骤3: 最后，在我的代码中这是我如何使用Helment添加外部JS文件

<Helmet>
    <script src = "path/to/my/js/file1.js" type = "text/javascript" />
    <script src = "path/to/my/js/file2.js" type = "text/javascript" />  
</Helmet>

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;

你可以在以下链接找到最佳答案:

https://cleverbeagle.com/blog/articles/tutorial-how-to-load-third-party-scripts-dynamically-in-javascript

const loadDynamicScript = (callback) => { const existingScript = document.getElementById('scriptId'); if (!existingScript) { const script = document.createElement('script'); 脚本。SRC = 'url';//加载的第三方库的URL。脚本。id = 'libraryName';//例如，googleMaps或stripe document.body.appendChild(脚本); 脚本。Onload = () => { If (callback) callback(); }; ｝ if (existingScript && callback) callback(); };

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>')

我有原始的html字符串与javascript/Jquery 我安装了NPM库dangerous -set-html-content NPM I危险地设置html内容

import InnerHTML from 'dangerously-set-html-content'
<div>
<InnerHTML html={html}/>
</div>

import InnerHTML from 'dangerously-set-html-content'
const renderhtml=`<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"><title> is not defined</title>$(document).ready(function(){    $("button").click(function(){        alert("jQuery is working perfectly.");    });      });</script></head><body>    <button type="button">Test jQuery Code</button></body></html>`

<div>
<InnerHTML html={renderhtml}/>
</div>

确保你添加了jquery cdn到public/index.html文件

 <script          src="https://code.jquery.com/jquery-3.3.1.min.js"          integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8="          crossorigin="anonymous"          async="true"        ></script>

要获得支持加载状态和错误处理的更完整的useScript实现，请查看useHooks。

使用

function App() {
  const status = useScript(
    "https://pm28k14qlj.codesandbox.io/test-external-script.js"
  );
  return (
    <div>
      <div>
        Script status: <b>{status}</b>
      </div>
      {status === "ready" && (
        <div>
          Script function call response: <b>{TEST_SCRIPT.start()}</b>
        </div>
      )}
    </div>
  );
}

Hook

function useScript(src) {
  // Keep track of script status ("idle", "loading", "ready", "error")
  const [status, setStatus] = useState(src ? "loading" : "idle");
  useEffect(
    () => {
      // Allow falsy src value if waiting on other data needed for
      // constructing the script URL passed to this hook.
      if (!src) {
        setStatus("idle");
        return;
      }
      // Fetch existing script element by src
      // It may have been added by another intance of this hook
      let script = document.querySelector(`script[src="${src}"]`);
      if (!script) {
        // Create script
        script = document.createElement("script");
        script.src = src;
        script.async = true;
        script.setAttribute("data-status", "loading");
        // Add script to document body
        document.body.appendChild(script);
        // Store status in attribute on script
        // This can be read by other instances of this hook
        const setAttributeFromEvent = (event) => {
          script.setAttribute(
            "data-status",
            event.type === "load" ? "ready" : "error"
          );
        };
        script.addEventListener("load", setAttributeFromEvent);
        script.addEventListener("error", setAttributeFromEvent);
      } else {
        // Grab existing script status from attribute and set to state.
        setStatus(script.getAttribute("data-status"));
      }
      // Script event handler to update status in state
      // Note: Even if the script already exists we still need to add
      // event handlers to update the state for *this* hook instance.
      const setStateFromEvent = (event) => {
        setStatus(event.type === "load" ? "ready" : "error");
      };
      // Add event listeners
      script.addEventListener("load", setStateFromEvent);
      script.addEventListener("error", setStateFromEvent);
      // Remove event listeners on cleanup
      return () => {
        if (script) {
          script.removeEventListener("load", setStateFromEvent);
          script.removeEventListener("error", setStateFromEvent);
        }
      };
    },
    [src] // Only re-run effect if script src changes
  );
  return status;
}
