I was wondering if anyone know whether the grid samples from Ext JS
are accessible.
http://extjs.com/deploy/dev/examples/samples.html or
http://extjs.com/deploy/dev/examples/grid/array-grid.html is a
specific example I am wondering about.
Thank you

Hi Nancy
I had a quick look at the links you provided and the answer is yes and
no. The grids are not seen as tables by Jaws so one cannot navigate in
a manner that is easy as with no column and row header info it can get a
bit confusing what company one is dealing with.
But as the info is linearised it is possible to search for the company
you are interested and once you have figured out the column headers it
is possible to understand the info as you arrow down the page.
So my answer is really yes I can get access to the information but from
an accessibility point of view I would say it needs work.

However, with JavaScript disabled, I was not able to access *any* of the
data. How big of an issue is this? Some stats
[http://www.thecounter.com/stats/2008/December/javas.php] suggest that up
to 6% of browsers are reporting that JavaScript is not being supported.

Nancy,
My opinion is that the array grid is not accessible. The content, at
the least, should be marked up as a table with row and column headings.
It might be possible for some people using screen readers to read and
comprehend the contents in the grid. However, the lack of good mark-up
would place the burden of interpreting the grid contents on the user's
abilities--such as can they remember the row and column headers as they
read the numerical data.
Also, you may want to look at the tasks the users will be performing
when they use a grid like this. It just occurred to me that if the user
needs to compare data across columns or rows, it might cause problems if
Ajax is being used to continually update the grid contents. If the user
is unaware the data just updated, the user might draw erroneous
conclusions when comparing data across columns and rows.
