Execute javascript code inside script-tag in React jsx-CodePudding

I am adding this script-tag to my React jsx render:

<script>alert('Hello world')</script>

Why is the Javascript code <script>alert('Hello world')</script> not executing in my React app?

Update:

I am debugging this because I get this HTML back from api:

<div  data-src="/event/66478667"></div>
<script>(function(d, s, id) {var js,ijs=d.getElementsByTagName(s)[0];if(d.getElementById(id))return;js=d.createElement(s);js.id=id;js.src="https://embed.widget.js";ijs.parentNode.insertBefore(js, ijs);}(document, 'script', 'my-js'));</script>

Now I am parsing this HTML through html-react-parser package like:

return <div data-testid="html-paragraph">{parser(html)}</div>;

But this isn't working because the Javascript code isn't executing?

How to solve this?

See here my code sandbox.

CodePudding user response：

Remove the <script> tag and replace with {}.

So: {alert('Hello world')}

CodePudding user response：

You can add it via npm package. I used it as ( once ):

import React, { Component } from 'react';
import ScriptTag from 'react-script-tag';
 
class Demo extends Component {
 
    render() {
        return (<ScriptTag isHydrating={true} type="text/javascript" src="some_script.js" />);
    }
}

Here is the npm package link https://www.npmjs.com/package/react-script-tag
