Checkpoint 6.5 : Programmatic operation of user agent user interface
Provide programmatic read access to user agent user interface controls, selection, content focus, and user interface focus.
If the user can modify the state or value of a user agent user interface control (e.g., by checking a box or editing a text area), allow programmatic read access to the current state or value, and allow the same degree of write access programmatically as is available through the user interface.
As part of satisfying provisions one and two of this checkpoint, implement at least one API according to the API cascade described in provision two of checkpoint 6.3.
Normative inclusions and exclusions
For security reasons, user agents are not required to allow instructions in content to modify user agent user interface controls. See more information on security considerations.
