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

[Hans-Jörg Bibiko]

Hi,

if I have an HTML page (TM's HTML output window) with embedded  
JavaScript and my JavaScript is not correct I can press the right  
mouse button and invoke 'Inspect Element' to look at the JavaScript  
error(s). Fine.

But is there a way to access the(se) error(s) from outside, I mean by  
a script?

If not, would it be possible to redirect the(se) error(s) to a log file?

Many thanks in advance,

--Hans
