http://www.w3.org/Bugs/Public/show_bug.cgi?id=13669 Summary: Indicating batch changes to the DOM Product: HTML WG Version: unspecified Platform: All OS/Version: All Status: NEW Keywords: a11y Severity: normal Priority: P2 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: gcl-0039@access-research.org QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org, public-html-a11y@w3.org There should be a method by which a script can signal the beginning and end of a batch of related changes to the document object. This will allow assistive technology to avoid dealing with transient intermediate states. Ideally it would be possible to indicate a specific portion of the document that is changing. This could also be implemented using a flag indicating a change is in progress. Use case: Nadia is using a screen reader while interacting with a page. She activates a button which causes the script to update significant amounts of the page's content, fetching new information from the web in a process that overall takes several seconds, perhaps with a pause or two in the middle. When the changes begin, Nadia's screen reader starts announcing them, but the process goes on with hundreds of different changes. Ideally, the script would fire a pair of events bracketing these changes, so the screen reader could tell Nadia that the page was updating but then not tell her more until the second event told it the update was completed. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
