when you write document.getElementById("myelement") your python linter (pylint or other) you tell undefine variable and don't suggesse you document methods in js
I suggess , like in this reposotory , to make python interface for javascript object and methods
I create folder named interfaces , inside yhis folder I create some class (like document,window, math ..), I import document in my code : hello.py given in transcrypt exemple, and I solve the probleme : my python linter recognize js document and suggest/complete when editng in Visual Studio Code IDE but transcrypt compiler skip interfaces import because my import is like this :
`#pragma ('skip')
from interfaces.document import document
from interfaces.math import Math
#pragma ('noskip')
