export default class Tabsshow extends React.PureComponent {
constructor(props) {
super(props);
this._ref = React.createRef();
}
render() {
return(
<div class="tradingview-widget-container" ref={this._ref}>
<div class="tradingview-widget-container__widget"></div>
</div>
);
}
componentDidMount() {
const script = document.createElement('script');
script.src = 'https://s3.tradingview.com/external-embedding/embed-widget-market-overview.js'
script.async = true;
script.innerHTML = /* JSON-ENCODED SETTINGS STRING FROM EMBED CODE */
this._ref.current.appendChild(script);
}
}
回答2:
This should work in your case
class App extends React.Component {
componentDidMount() {
const script = document.createElement('script');
script.src = 'https://s3.tradingview.com/external-embedding/embed-widget-market-overview.js'
script.async = true;
script.innerHTML = JSON.stringify({ /* JSON object */})
document.getElementById("myContainer").appendChild(script);
}
render() {
return(
<div id="myContainer">
<div className="tradingview-widget-container">
<div className="tradingview-widget-container__widget">
</div>
</div>
</div>
);
}
}

I suggest you to use React Helmet
Below is a given demo:
import React from "react";
import {Helmet} from "react-helmet";
class Application extends React.Component {
render () {
return (
<div className="application">
<Helmet>
<meta charSet="utf-8" />
<title>My Title</title>
<link rel="canonical" href="http://example.com/example" />
</Helmet>
...
</div>
);
}
};
You can also add your script in your code. Let me know if it helps you.
EDITED
In your case, you can do the following:
import React from "react";
import {Helmet} from "react-helmet";
export default class MyPro extends Component {
render() {
return (
<Helmet>
<script type="text/javascript" src="https://s3.tradingview.com/external-embedding/embed-widget-market-overview.js" async>
