NavigationDestination: sameDocument property - Web APIs | MDN
NavigationDestination: sameDocument property Limited availability
The sameDocument
read-only property of the
NavigationDestination
interface returns true
if the navigation is to the same document
as the current Document
value, or false
otherwise.
This is useful for checking whether the navigation will be same-document or cross-document.
navigation.addEventListener("navigate", (event) => {
console.log(event.destination.sameDocument);
});
