This is not the correct way because createText
is a event handler it will not render the element, what you need is “Conditional rendering of elements”.
Check Docs for more details Conditional Rendering.
Steps:
1- Use a state variable with initial value false
.
2- Onclick of button update the value to true
.
3- Use that state value for conditional rendering.
Working Code:
class App extends React.Component {
constructor() {
super();
this.state = {
isShow: false
}
this.createText = this.createText.bind(this);
}
createText() {
this.setState({ isShow: true })
}
render() {
return (
<div className="App">
<button onClick={this.createText}>Click</button>
{this.state.isShow && <p>Hello World!!!</p>}
</div>
);
}
}
ReactDOM.render(<App />, document.getElementById('app'))
