How can I implement keyboard navigation for accessibility in Angular?
To implement keyboard navigation in Angular, you can use the Angular CDK's a11y package, which provides utilities for managing focus and keyboard events.
Can you give me an example of how to use the CDK for this?
Sure! You can use the FocusKeyManager
to manage focus on a list of items. Here's a simple example:
import { FocusKeyManager } from '@angular/cdk/a11y';
export class MyComponent {
keyManager = new FocusKeyManager(this.items);
handleKeydown(event: KeyboardEvent) {
this.keyManager.onKeydown(event);
}
}
What about handling focus when navigating with arrow keys?
You can extend the FocusKeyManager
to handle arrow key navigation by listening for the arrow key events and updating the focus accordingly. Make sure to call keyManager.setFirstItemActive()
to set the initial focus.
Are there any best practices for keyboard navigation in Angular?
Yes, some best practices include ensuring all interactive elements are focusable, providing clear focus indicators, and testing your navigation with a keyboard only.
