Tab switch or application switch?

Is there a way to distinguish between different browser events in the following scenarios?

  • When the user clicks on another tab within the same browser, causing my tab to be hidden and should pause.
  • When they switch to another application, with my tab potentially still visible and should continue running.

It seems that identical blur/focus DOM events are triggered in each case, providing no solution.

In simpler terms, can it be determined if a tab is currently being displayed to the user?

(By the way, I do not need this functionality in non-WebGL browsers like IE.)

javascript

Answer №1

To ensure functionality, you can attach the events focus and blur to the window.

Here is an example:

$(window).focus(function() {
   //resume
});

$(window).blur(function() {
   //halt
});
