Bob & Scott,
I've tried both of your suggestions without success. The situation is
critical now as an individuals employment counts on resolving this. I've
done some more experimenting and have discovered the following.
When using Internet Explorer 8 under Windows 7 with either Jaws 13 or 15 the
code I've reposted below successfully captures the text on a web page. For
this test I've used Freedom Scientifics home page but the web page doesn't
seem to be significant.
With either IE 9 or IE 11 the code returns nothing. I've been unable to
come up with any script code that can use the DOM to access text in IE 9 or
IE 11. Can use of the DOM be broken in Jaws as regards newer versions of
IE? If so, that's a very serious problem.
I'm deperate at this point - if anyone can demonstrate Jaws code that
successfully uses the DOM to access text in IE 9 or 11 please post it. My
code that works in IE 8 follows:
String Function WorkSpaceText ()
var
object doc,
object win,
string sBuffer
Let doc = ieGetCurrentDocument ()
Let win = ieGetUnrestrictedWindow(doc).document.body
Let sBuffer = win.createTextRange().text
return sBuffer
EndFunction

The one thing I can tell you about DOM manipulation techniques within JAWS
scripts is that JAWS absolutely hates chaining the object methods more than
one layer deep. In a number of instances, I've found that while the chain is
conceptually sound, the function only works if I walked the individual calls
into variables. Example from below, "oFrame.document.body.innerText" is a
valid call in JavaScript, but in JAWS script you may find it only works if
you do it like this:
let oDOM = ieGetCurrentDocument ()
let oFrame = oDOM.frames(2)
let oObject = oFrame.document
let oObject = oObject.body
let sText = oObject.innerText

I have no idea what the difference is but I
have always used
IeGetCurrentDocument when
playing with the DOM.
I would try something
like the following:
String
Function GetFrameContents ()
Var
Object oDOM,
Object oFrame,
String sFrameText
Let oDOM =
ieGetCurrentDocuemnt ()
Let oFrame =
oDOM.frames(2)
Let sFrameText =
oFrame.document.body.innerText
Return sFrameText
EndFunction
You may need to fiddle with the document.body.
and the innerText to maybe
innerHTML or
outerText dependant on what sort of output you need.
You also need to take into account the origin
of the frame contents. To
increase security
modern browsers prevent scripts from running from a
different domain. If the frame contents are
from http://siteA.com and the
main page is http://siteB.com
you wont be able to access it.
Hope this helps.
Bob

using DOM in IE 11
I'm
having a problem capturing text from an HTML frame using the
DOM in IE
11. This is Windows 7 and Jaws
15.
The following code works with IE8 and
Jaws 13 but not with IE 11 and Jaws
15:
String Function WorkAreaText ()
var
object doc,
object
TopWindow,
object win,
object frames,
string
sBuffer
Let doc =
ie4GetCurrentDocument ()
Let topWindow = doc.parentWindow
Let topWindow
= topWindow.top
Let frames = TopWindow.frames
Let win =
ieGetUnrestrictedWindow(frames(2)).document.body
Let sBuffer =
win.createTextRange().text
return sBuffer ;the text in the frame
EndFunction
I'd
appreciate any suggestions.
Also can anyone explain the difference between
ie4GetCurrentDocument ()and
ieGetCurrentDocument ().
Although I've successfully used the
function ieGetUnrestrictedWindow() many
times in the manner shown above I've never
seen a good explanation of it.
Can anyone
explain it?
