Hello!

How can I track if a user is on a tab? Those. the page loads, I click on another browser tab and a certain function is executed on my page. When I click the page tab again, another function is executed.

Thank you in advance.

    This can be done with the usual focus and blur events by applying them to the window object.

    Example:

    $(window).focus(function() { console.log( 'Вкладка открыта! :)' ); }); $(window).blur(function() { console.log( 'Вкладка не открыта! :(' ); }); 
     <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

    Example without jQuery:

     window.onfocus = function() { console.log( 'Вкладка открыта! :)' ); }; window.onblur = function() { console.log( 'Вкладка не открыта! :(' ); };
