As shown in the picture, why is 1 also refreshed when 2 is refreshed in a background project made by PHP?

Question

][1]

Answer 1

Look at the specific code yourself, so you can’t tell it from the interface. It may be that when you do some database-related operations in 1, 2 monitors the database operations and automatically refreshes them with js.

Answer 2

Thanks for the invitation!

There are many ways to achieve it:

1) ajax polling
2) php websocket, message push, the message in 2 is pushed to 1 instantly
3) html postMessage cross-window messaging

In fact, it is all about letting 1 get updated news
