How to detect if a page has focus (onload)

Question

Please I'd like to count the time spent on a given page. In order to do this, I need to know when the page is opened in new tab, without focus and then start counting when the tab has focus.

$(window).focus(function() {
    window_focus = true;
}).blur(function() {
    window_focus = false;
});

The above works well when the has already loaded on a focused tab. How can I know when a page is fully loaded without focus.

Didn't quite get the question. What's the problem again? – weirdpanda Jan 14 '16 at 14:03 — weirdpanda, Jan 14 '16 at 14:03

Use the setInterval for setting the tick on the focused page and clear it when it loses focus.

On page load when the page is not focused on (ie, user opened the page in new tab), count begins. How do I detect that the user is not focused on the page and wait for user to focus on the page before starting count? – Overcomer Jan 14 '16 at 14:44
