:focusable Selector


focusable selector

Description: Selects elements which can be focused.

  • jQuery( ":focusable" )

Some elements are natively focusable, while others require explictly setting a tab index. In all cases, the element must be visible in order to be focusable.

Elements of the following type are focusable if they are not disabled: input, select, textarea, button, and object. Anchors are focusable if they have an href or tabindex attribute. area elements are focusable if they are inside a named map, have an href attribute, and there is a visible image using the map. All other elements are focusable based solely on their tabindex attribute and visibility.

Note: Elements with a negative tab index are :focusable, but not :tabbable.

Example:

Select focusable elements and highlight them with a red border.
