Vue Lookup - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
Alt + ↓ | Opens the drop-down menu. |
Enter or Space | 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. |
Page Up / Page Down | Moves focus to the first/last menu item on the page. |
Home / End | Moves focus to the first/last menu item. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
- <template>
- <DxLookup :ref="myLookupRef" />
- </template>
- <script>
- import 'devextreme/dist/css/dx.light.css';
- import DxLookup from 'devextreme-vue/lookup';
- const myLookupRef = 'my-lookup';
- export default {
- components: {
- DxLookup
- },
- data() {
- return {
- myLookupRef
- }
- },
- computed: {
- lookup: function() {
- return this.$refs[myLookupRef].instance;
- }
- },
- mounted: function() {
- this.lookup.registerKeyHandler('backspace', function(e) {
- // The argument "e" contains information on the event
- });
- this.lookup.registerKeyHandler('space', function(e) {
- // ...
- });
- }
- }
- </script>
