Top. Location. href = "/url" opens a new page on the top page.

 

Top. Location. href = "/url"
It means opening the URL on the top-level page
Self. Location. href = "/url"
It is said that only the URL address opened on this page is
Parent. Location. href = "/url"
The URL address opened in your window
