What is the simplest way to create an tag that links to the previous web page? Basically a simulated back button, but an actual hyperlink. Client-side

Answer 1

history.go(-1) doesn't work if you click around in the 2nd domain or if the referrer is empty.

So we have to store the historyCount on arriving to this domain and go back the number of navigations in this side minus 1.

// if referrer is different from this site
if (!document.referrer.includes(window.location.host)) {
  // store current history length
  localStorage.setItem('historyLength', `${history.length}`);
}

// Return to stored referrer on logo click
document.querySelector('header .logo').addEventListener('click', 
  () =>
   history.go(Number(localStorage.getItem('historyLength')) - history.length -1)
);
