[NFBCS] Using the Chrome Console

[dan.tevelde at comcast.net]

Hi Lewis,

This does sound easier. I am editing JavaScript in Visual Studio from within
a Ubantu distribution. For the most part Visual Studio works well except
that sometimes cursor routing on my Mantis Braille display will move the
cursor to the top of the window instead of the line where I have an error I
want to fix. As far as I can tell NVDA treats the Visual Studio editor as
though I am in browse mode. I get the NVDA browse mode sound when Visual
Studio opens. If I switch to forms mode, the cursor moves to the top of the
screen and I can't move the cursor. This seems weird to me. You would think
the opposite would be true.

If I am working on assignments for school where they are teaching test
driven development and debugging. I can easily open the Chrome console and
type JavaScript or paste code I have written somewhere else. The problems
start when I try to find the correct tools tab to expand. Even if I get into
the JavaScript debugger tool the function keys listed on the Google support
page for the Chrome console don't work. I suppose if I am working on a group
assignment I could edit in Visual Studio and copy into the Chrome console so
a student working with me could compare what
I am doing to what they are doing. I think the problem is solvable, but I
will need to take the different approach you are suggesting. I haven't yet
gotten into HTML and CSS, but I would imagine the same principles would
apply.

I personally prefer vsCode for my javascript debugging. Although vsCode
works better if the javascript is an external .js file.

To debug from vsCode do the following:
1) Open html file in browser first.  And Copy the address from the bar. Then
close it.
2) in vsCode press ctrl + shift + P, to debug a link.
3. Paste the address from the step 1.
4) now you are debugging until you shut down the browser.

Set break points, and inspect variables as usual.
F10 and f11 stepover and step into. See debug windows.

Ctrl + shift + "y" is java console hot key. Press again to return to editor.
IN the javaconsole you will find shift + tab puts you in a console tree.
This console tree is the output from your javascript.  You can clear it,
copy, etc using application key menu..

Set breakpoints and everything.  Also tab to variables while at a
breakpoi9nt. All the variables, local and blobal are available.  You can
even edit them.
Simply type in a variable or formala and the java console will output it.
Then do the shift tab for the tree.

I hope this helps..

I am trying to debug JavaScript but the keyboard commands f8 to run, f10 to
step over, and f11 to step into aren't working. I think the step over
command is supposed to position the cursor on a specific line to begin code
execution from that point. I am using NVDA and must continue to switch from
forms mode to browse mode to run commands and read results. I did a Google
search and found a list of possible keyboard shortcut keys, but they weren't
helpful.

 

Thanks,

Dan
