Re: Detecting types of web technologies (JQuery/AJAX)

I guess, in retrospect, the situation I am contemplating is probably
too tricky to be easily solved with code.
The reason I initially asked was that I am a blind tested, and I only
use keyboard, so any mouse-only feature of a page is something that it
is hard for me to detect.
I asked a sighted colleague of mine because the group of words on the
page looked like links, but Jaws did not announce them as such, so I
was wondering what they were.
But if something is inaccessible from the keyboard, a blind person who
only uses the keyboard will not find out about them without sighted
If some kind of technology analysis could be run on a page it might
indicate the likelyhood of something being only accessible from the
keyboard, so that a blind user could get an idea of the possible
presence of those elements, and could then seak sighted assistance to
investigate the page.
But, as has been pointed out, the use of AJAX doesnotnecessary mean
the pageis inaccessible, it depends on the specific use, the
screenreader etc.
