Angular Tabs - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
← ↑ or PageUp | Moves focus to the previous tab. |
→ ↓ or PageDown | Moves focus to the next tab. |
Home | Moves focus to the first tab. |
End | Moves focus to the last tab. |
Enter or Space | Selects the tab. Available only if selectionMode is set to 'multiple'. |
Shift + Mouse Wheel | Scrolls the tabs left/right if the scrollingEnabled property is true. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { const tabs = $("#tabsContainer").dxTabs("instance"); tabs.registerKeyHandler("backspace", function(e) { // The argument "e" contains information on the event }); tabs.registerKeyHandler("space", function(e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from '@angular/core'; import { DxTabsModule, DxTabsComponent } from 'devextreme-angular'; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxTabsComponent, { static: false }) tabs: DxTabsComponent; // Prior to Angular 8 // @ViewChild(DxTabsComponent) tabs: DxTabsComponent; ngAfterViewInit () { this.tabs.instance.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tabs.instance.registerKeyHandler('space', function(e) { // ... }); } } @NgModule({ imports: [ // ... DxTabsModule ], // ... })
Vue
<template> <DxTabs :ref="myTabsRef" /> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxTabs from 'devextreme-vue/tabs'; const myTabsRef = 'my-tabs'; export default { components: { DxTabs }, data() { return { myTabsRef } }, computed: { tabs: function() { return this.$refs[myTabsRef].instance; } }, mounted: function() { this.tabs.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tabs.registerKeyHandler('space', function(e) { // ... }); } } </script>
React
App.js
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Tabs } from 'devextreme-react/tabs'; class App extends React.Component { constructor(props) { super(props); this.tabsRef = React.createRef(); } render() { return ( <Tabs ref={this.tabsRef} /> ); } get tabs() { return this.tabsRef.current.instance; } componentDidMount() { this.tabs.registerKeyHandler('backspace', function(e) { // The argument "e" contains information on the event }); this.tabs.registerKeyHandler('space', function(e) { // ... }); } } export default App;
