Actually the code given in this post is working - Would it be a good idea to implement in TW to update the infomechanism when entering/leaving fullscreen? - #2 by EricShulman
Error in the tiddlywiki-app occurred when I used the code given in the TiddlyTools site - TiddlyTools for TW v5.3.6 — Small Tools for Big Ideas!™. But this code worked in my browser.
I thought both codes were the same and took the one from TiddlyTools site thinking that it might be a updated version. Sorry for the confusion guys.
@EricShulman any particular reason why one code shows error while the other doesn’t. It would be better to give both code in TiddlyTools website since both have separate usecases
