And from what I remember (speaking of first hand experience with JAWS,
so can't vouch for any other screenreaders), whether or not the
screenreader is present does not stop the DOM-changing javascript to be
executed in IE (it runs as it normally would), but the screenreader
itself only becomes aware of it if the changes were a result of user
interaction (activating a link, putting the focus on an element, etc)

Found this document a while ago, not sure if it still applies to the
very latest version (never mind the behaviour of other screenreaders):


"Q: How can I expect JAWS to handle JavaScript on my Web page?

A: JAWS will work correctly with JavaScript if:

* The scripts are activated by clicking a link or clickable item and the
script dynamically updates the HTML source.
* The scripts do not update the page without user intervention."
