DevExtreme Vue - Keyboard Support
An end user can use the following keys to interact with the widget.
Key | Action |
---|---|
Alt + ↓ | Opens the drop-down menu. |
Enter or Backspace | If the drop-down menu is closed, opens it; otherwise selects the current item. |
Esc | Closes the drop-down menu. |
↑ / ↓ | If the drop-down menu is opened, moves focus to the previous/next item. |
Tab / Shift + Tab | If the drop-down menu is opened, moves focus to the list / search field. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
jQuery
JavaScript
function registerKeyHandlers () { let lookup = $("#lookupContainer").dxLookup("instance"); lookup.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); lookup.registerKeyHandler("space", function (e) { // ... }); }
Angular
TypeScript
import { ..., ViewChild, AfterViewInit } from "@angular/core"; import { DxLookupModule, DxLookupComponent } from "devextreme-angular"; // ... export class AppComponent implements AfterViewInit { @ViewChild(DxLookupComponent) lookup: DxLookupComponent ngAfterViewInit () { this.lookup.instance.registerKeyHandler("backspace", function (e) { // The argument "e" contains information on the event }); this.lookup.instance.registerKeyHandler("space", function (e) { // ... }); } } @NgModule({ imports: [ // ... DxLookupModule ], // ... })
