问题
On a webpage, I have a number of events for which you can buy a ticket. When you press a button for a event, a number of prices will be visible inside the div of the event (they are made visible with javascript).
How do I signal to accessibility programs that they should start read the contents of the newly visible div? Does this fall into the "popup" category?
I ask this question again because it was incorrectly migrated to the superuser forum.
