javascript - After the angulajs page is minimized, the countdown timer stops

There is a countdown on the page
After the angulajs page is minimized, the countdown timer stops
After the chrome browser is minimized, the countdown stops. After maximizing, the time before minimizing continues to count down.
The same thing happens when entering the mobile page. Is there any solution?

I don’t know whether it refers to PC or mobile phone. This situation is normal on mobile phones and is a system feature (probably to save power)
