Endless page refresh [duplicate]

Question

I wanted the page to refresh after 1 second and that's it, but after 1 second I get an infinite page refresh. How to fix endless page refresh?

function sayHi() {
  document.location.reload();
  return false;
}
setTimeout(sayHi, 1000);

<div class="timer">
  Infinity refresh =(
</div>

Answer 1

When you reload the page, it's going to run the setTimeout again. You can use sessionStorage to make sure you refresh once per session.

if(!sessionStorage.getItem('refreshed')) {
    sessionStorage.setItem('refreshed', true);
    setTimeout(sayHi, 1000);
}
