JavaScript/jQuery 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.
JavaScript
- function registerKeyHandlers () {
- const lookup = $("#lookupContainer").dxLookup("instance");
- lookup.registerKeyHandler("backspace", function(e) {
- // The argument "e" contains information on the event
- });
- lookup.registerKeyHandler("space", function(e) {
- // ...
- });
- }
