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

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>')

其他回答

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);
}

与其他答案非常相似，只是使用默认值来清理未定义的检查

import { useEffect } from 'react'

const useScript = (url, selector = 'body', async = true) => {
  useEffect(() => {
    const element = document.querySelector(selector)
    const script = document.createElement('script')
    script.src = url
    script.async = async
    element.appendChild(script)
    return () => {
      element.removeChild(script)
    }
  }, [url])
}

export default useScript

使用

useScript('/path/to/local/script.js') // async on body
useScript('https://path/to/remote/script.js', 'html') // async on html 
useScript('/path/to/local/script.js', 'html', false) // not async on html.. e.g. this will block

我最近遇到了一个问题，尝试了这里给出的多种解决方案，最终满足于iframe，如果你想在特定的屏幕上集成一个js插件，Iframe似乎可以无缝地工作

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>

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')
