How to manage focus in a Vue application for accessibility?
Article Introduction：Managing focus in Vue applications requires using ref to control focus, ensuring a reasonable tab order, processing dynamic content focus, and adding ARIA attributes. First, use ref to set the focus to specific elements, such as the input box in the modal box after the component is mounted; second, maintain the natural Tab order by semanticizing HTML tags and avoiding manual setting of tabindex; third, use life cycle hooks or watcher to adjust the focus position when dynamic content such as modal box or drop-down menu is displayed or hidden; finally, add aria-expanded, aria-label and other attributes to the component to improve the accessibility experience.
