[TxMt] HTML output window: How to access JavaScript errors

[Hans-Jörg Bibiko]

Hi,

I have an HTML page running in TM's HTML output window with embedded  
JavaScript and my JavaScript is not correct, I can invoke 'Inspect  
Element' to see the error. Fine.

But is there a way to access the error message from outside, I mean  
by a script?

If not, would it be possible to redirect the JavaScript error  
messages to a log file?

Many thanks in advance,
