Hey everyone - Jayson again; and now that i have started with flask i have attempted one of my older programming ideas with the addition of a realtime printout or 'CONSOLE', of course in Python3.
I would like to use python CGI to display a realtime python subprocess stdout console.
I am having trouble now, getting the console iframe to update, only works when i right click and say reload frame....kinda still my last error is javascript/python
[attachment=1679]
[attachment=1678]
ANY HELP???
here are the 3 pages that are in /cgi-bin serving the web program:
ostemplate.py
