First you need to understand React's philosophy. I strongly suggest you read the official React tutorial: https://reactjs.org/tutorial/tutorial.html.
In this case you would like to appear and disappear a div, this can be accomplished by changing internal state of a React Component. Then you need to create a function that is bound to the context of the instance of the Component.
For example:
class Example extends Component {
constructor(props) {
super(props);
this.state = {
open: true,
};
}
toggle() {
const { open } = this.state;
this.setState({
open: !open,
});
}
render() {
const { open } = this.state;
return (
<main>
<button onClick={this.toggle.bind(this)}>{open ? 'Hide' : 'Show'}</button>
{open && <div id="example"><h1>this is example</h1></div>}
</main>
);
}
}

thank you for your information, maybe i did not describe correctly, so it should be something like this: <div id="example">example</div> <div id="root"></div>, so how can i hide and show the first "example" in the class that "root" has ?
– fong lee
Nov 15 at 14:47
why would you need React then ? Just do some:document.querySelector('#example').style.display = 'none';
