I'm trying to create a new portal with an id.
This is the index html file in the public folder:
<body>
<noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
<div id="other"></div>
</body>
And here I tell react to render this component inside the div with the id of root:
import React from 'react';
import ReactDOM from 'react-dom';
function New() {
return ReactDOM.createPortal(<h1>DEMO</h1>, document.getElementById('other'));
}
export default New;
But when I npm start I dont see anything inside the div with the id of other.
How can I create a new portal in react js properly?
I solved the problem by including the New component inside App.js file:
import React from 'react';
import logo from './logo.svg';
import './App.css';
import New from './New';
function App() {
return (
<div className="App">
<New />
</div>
);
}
export default App;
And when I inspect it, the New component is actually inside the div with the id of other.
