JavaScript/jQuery DropDownButton - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
← | Moves focus to the action button when splitButton is enabled. |
→ | Moves focus to the toggle button when splitButton is enabled. |
Enter / Space | Opens the drop-down menu when the toggle button is focused. |
Simulates a click action when the action button is focused. | |
Selects a menu item when focused. | |
↑ / ↓ | Moves focus to the previous/following menu item. |
↓ | Opens the drop-down menu. |
Esc | Closes the drop-down menu. |
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 dropDownButton = $("#dropDownButtonContainer").dxDropDownButton("instance");
- dropDownButton.registerKeyHandler("backspace", function(e) {
- // The argument "e" contains information on the event
- });
- dropDownButton.registerKeyHandler("space", function(e) {
- // ...
- });
- }
