In this lesson, we will see how to check if a tab is active in JavaScript, sometimes we want to know if the user is still in a tab or he has moved to another one, so how can we do that?
Check if a tab is active
To do that use the code below where we check if the visibility of the tab has changed then we alert a message telling the user that the tab is not active.
function checkIfTabIsActive() { if(document.hidden) alert('tab is not active');}
document.addEventListener("visibilitychange",checkIfTabIsActive);
