'How to load script in react component

I am having following script file

<script language="javascript">

document.write('<script language="javascript" src="http://tickettransaction.com/?bid='+bid+'&sitenumber='+site+'&tid=event_dropdown" ></' + 'script>');
</script>

I follow this Adding script tag to React/JSX but it does not work for me...

How do I load the script in my react component?

Solution 1:^[1]

After a lots of R&D finally I found my solution.

I have used npm postscribe to load script in react component

postscribe('#mydiv', '<script language="javascript" src="http://tickettransaction.com/?bid='+bid+'&sitenumber='+site+'&tid=event_dropdown"></script>')

the following method is worked for me. try, hope it will work for you. basically, you can create a script tag and append it to the body tag. like this--

var tag = document.createElement('script');
tag.async = true;
tag.src = 'THE PATH TO THE JS FILE OR A CDN LINK';
var body = document.getElementsByTagName('body')[0];
body.appendChild(tag);

you can use this on a life cycle hook of react like this.

componentDidMount() {
    var loadScript = function (src) {
      var tag = document.createElement('script');
      tag.async = false;
      tag.src = src;
      var body = document.getElementsByTagName('body')[0];
      body.appendChild(tag);
    }

    loadScript('PATH TO THE JS FILE OR CDN URL');
  }

A 2021 TypeScript example using functional components that works with NextJS

(ensures code only runs client-side)


declare global {
  interface Window {
    hbspt: any
  }
}

export default function Contact() {
  useEffect(() => {
    if (window && document) {
      const script = document.createElement('script')
      const body = document.getElementsByTagName('body')[0]
      script.src = '//js.hsforms.net/forms/v2.js'
      body.appendChild(script)
      script.addEventListener('load', () => {
        window.hbspt.forms.create({
          // this example embeds a Hubspot form into a React app but you can tweak it for your use case
          // any code inside this 'load' listener will run after the script is appended to the page and loaded in the client
        })
      })
    }
  }, [])

  return <div id="hbspt-form" className="p-5"></div>
}

I recommend using React Helmet. I've used it on a couple of Create-React-Apps, and it allows you to write actual script tags combined with vanilla JS.

It makes the process a lot smoother. So for you it'd be something like this once you've imported React Helmet.

<script language="javascript" src='http://tickettransaction.com/?bid='+ bid + '&sitenumber='+ site +'&tid=event_dropdown' ></ script>

This came to my rescue. This is the easiest way to load Script Tags

https://www.npmjs.com/package/react-script-tag

import ScriptTag from 'react-script-tag';

const Demo = props => (
<ScriptTag src="/path/to/resource.js" />
);

There are other ways to do this too :
