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>
