DevExtreme React - Keyboard Support

An end user can use the following keys to interact with the widget.

Key Action
Enter or Space Changes the widget value.
Changes the switch state to "On".
Changes the switch state to "Off".

You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.

App.js
  • import React from 'react';
  • import 'devextreme/dist/css/dx.common.css';
  • import 'devextreme/dist/css/dx.light.css';
  •  
  • import { Switch } from 'devextreme-react/switch';
  •  
  • class App extends React.Component {
  • constructor(props) {
  • super(props);
  •  
  • this.switchRef = React.createRef();
  • }
  •  
  • render() {
  • return (
  • <Switch ref={this.switchRef} />
  • );
  • }
  •  
  • get switch() {
  • return this.switchRef.current.instance;
  • }
  •  
  • componentDidMount() {
  • this.switch.registerKeyHandler('backspace', function(e) {
  • // The argument "e" contains information on the event
  • });
  • this.switch.registerKeyHandler('space', function(e) {
  • // ...
  • });
  • }
  • }
  •  
  • export default App;
