to show an alert once user backs to a page

Question

There are two pages, and I want to show an alert on the first page when the user comes back from second page to first page.

I know how to go back to first page by: window.location.href

and also by: window.history.back().

But I don't know how to show an alert once it's backed?

You can simply achieve it using localStorage or sessionStorage.

// Page 1

const visited = localStorage.getItem("visited")

if(visited) alert("//Do something here, why you came back")

else localStorage.setItem("visited", "visited")

You can give the url a parameter and use it to check whether an alert message should be fired.

For example: window.location.search -> '?visited=true'
