To get keyboard navigation using arrow keys between elements you can do the following:
import Controls from 'h5p-lib-controls/src/scripts/controls';
import UIKeyboard from 'h5p-lib-controls/src/scripts/ui/keyboard';
// Add support for arrow keys + HOME + END
const controls = new Controls([new UIKeyboard()]);
// Add support for ENTER and SPACE
controls.on('select', event => console.log('user selected element', event.element));
// Add support for ESC
controls.on('close', event => console.log('perform closing action'));
import Controls from 'h5p-lib-controls/src/scripts/controls';
import UIKeyboard from 'h5p-lib-controls/src/scripts/ui/keyboard';
import AriaSelected from 'h5p-lib-controls/src/scripts/aria/selected';
// this control will also apply [aria-selected="true"] on select event
const controls = new Controls([new UIKeyboard(), new AriaSelected()]);
import Controls from 'h5p-lib-controls/src/scripts/controls';
import AriaDrag from 'h5p-lib-controls/src/scripts/aria/drag';
import AriaDrop from 'h5p-lib-controls/src/scripts/aria/drop';
import UIKeyboard from 'h5p-lib-controls/src/scripts/ui/keyboard';
// trigger [aria-grabbed="true"] with keyboard
const dragControls = new Controls([new UIKeyboard(), new AriaDrag()]);
// trigger [aria-dropeffect="move"] with keyboard
const dropControls = new Controls([new UIKeyboard(), new AriaDrop()]);
By default h5p-lib-controls will remove [tabindex]
from the elements that are not selected. If you instead want to use [tabindex="-1"]
, you can do the following:
const controls = new Controls([new UIKeyboard()]);
controls.useNegativeTabIndex();
