Is it possible to use JavaScript to edit frame.js?

I suspect SL processes the options you have identified once, at lesson launch, so changing the value - which is possible through direct manipulation of the browser's document object model (DOM), would not result in rendered/visual functionality

In fact i have this worked out quite a while ago.

...and came to the conclusion that instead of stopping and restarting the events.. it might be much easier to just block the list items. Thus said and done.. and it works flawless.

One big plus of this approach is that you can customize the menu/listitems if you want to.

As you can see in the second review.
And here is the working Storyline.

Noticing just now that you point to my solution and ask if and how to fix it in Articulate's JS files.
Well you can change the frame JS-files in your Articulate folder at will and then it behaves exactly as you want. Problem however is that on every update the files will be erased and you have to redo it. You could try and override the generated frame.desktop.min.js  from within Storyline, but as all code in Articulate is minified and heavily obsfuscated...well it is a real puzzle to get it working..and as said before...every update will change things...

If someone else has this need in the future, my final solution was to create a batch file that automatically updates the menuOption to restricted.

I know is a very specific need, but maybe it will help someone else later :)

Since I can't attached files somehow, here is the code:

@echo off

REM Set the search text and replace text
set "search_text=\"free\""
set "replace_text=\"restricted\""

REM Determine the current directory and specify the file path
set "main_folder=%cd%"
set "file=%main_folder%\html5\data\js\frame.js"
set "temp_file=%file%.tmp"

REM Check if the file exists
if not exist "%file%" (
echo File not found: %file%
pause
goto :eof
)

echo Processing file: %file%

REM Use PowerShell to read and modify the file, writing to a temporary file
powershell -Command ^
"Get-Content '%file%' | ForEach-Object { $_ -replace '%search_text%', '%replace_text%' } | Set-Content '%temp_file%'"

if %errorlevel% neq 0 (
echo Error processing the file with PowerShell.
pause
goto :eof
)

REM Replace the original file with the modified temporary file
move /y "%temp_file%" "%file%" >nul

if %errorlevel% neq 0 (
echo Error replacing the original file.
) else (
echo Updated file: %file%
)

echo Done!
pause
