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;
