Question

Let’s say a user navigates from greatsite.com/uno#argument to coolsite.com/dos. After some interaction on the second page, I need to send him back to his referrer with Javascript:

window.location = document.referrer;

The problem with running this is that document.referrer loses the hash values. The user gets redirected to website.com/uno without #argument. The page fails to work because its javascript depends on that argument.

Answer 1

what about using the history ?

if (history.back() === undefined) location.replace(document.referrer);
