javascript cross page variables not working

Question

i have this javascript script shared between all my web pages:

if(document.location.pathname == '/' || document.location.pathname == '/index.php'){
window.hello='hello';
window.alert(window.hello);
}
else
{
window.alert(window.hello);
}

the window.hello variable should be (as far as i know) a cross page variable, so it should display 'hello' in every page (having first loaded index.php), but that happens only in the index page, while the others display 'undefined' .... someone knows why?

"the window.hello variable should be (as far as i know) a cross page variable" — Entirely untrue. Variables exist only in the current page. — Quentin, Dec 20 '17 at 14:30

window.hello is a global variable and is added as a property to the global object.

A new global object is created for each page, hence your problem...

Possible solutions: include the same script in all your pages (if it is a constant), localStorage, sessionStorage, cookie, URL or roundtrip to the server, etc. – Ben Aston Dec 20 '17 at 14:33
what about sessionStorage? – Alessandro Cocco Dec 20 '17 at 14:39
