- Modificato
Marcin I gave credit to "frutis" because I started from his infos http://www.bez-kabli.pl/viewtopic.php?f=11&t=47687&p=622849#p622849 found with google and the rest I discovered on my own with Chrome debugger. I didn't find your tutorial and if I understand you used a different approach in debugger modifying HTML element while I simply modified a variable in a breakpoint (you should try as it is faster for experiments).
