I'd like to add a timer to one page of my app that:
counts up whenever a user is on the page
pauses the user leaves the page
restarts where it left off when the user re-opens the page
Any ideas of an efficient way of implementing this? I've tried:
using the timer widget. This doesn't work as the timer restarts every time the user leaves the page
Using page parameters and a periodic action. This doesn't work as the periodic action continues even when a user leaves the page
Thanks in advance,
Dan
