How to control the popup is opened once:
When the page is first opened, a .js file will be called in the code, and a window will pop up in the .js file.
What if the window controlled by the .js file no longer pops up when the page is refreshed when the pop-up window is not closed?

Wait online!

It ’s better to use cookies,
When the page opens, check whether the cookie exists. If it does not exist, a pop-up window will be displayed.

When the pop-up window is unloaded from the body, clear this cookie. This way, if the pop-up window exists, it will no longer pop up. If it does not exist, it will pop up.
