The Document.onvisibilitychange
property represents the
event handler that is called when a visibilitychange
event reaches this
object.
Safari doesn’t fire the
visibilitychange
event as expected when visibilityState
transitions to
hidden
; so for that case, you need to also include code to listen for the
pagehide
event.
Syntax
obj.onvisibilitychange = function;
function
is the name of a user-defined function, without the () suffix or any parameters, or an anonymous function declaration.
Example
document.onvisibilitychange = function() {
console.log("Visibility of page has changed!");
};
