window.onfocus() doesn't work on remote server

Question

I want to execute some code when user activate the browser's tab.

window.onfocus = function() {
  console.log('323');
};

On localhost this works, but doesn't work on remote server. Console is empty.

I also tried without success:

$(window).bind('focus', function() {
      console.log('323');
});

My browser is Chrome, last version.

Have you double checked the code exists on the remote server? What browser are you using? — timothyclifford, Dec 08 '16 at 16:27
Your first method should be fine, and it shouldn't matter where you're running it from as it's all running locally (in your browser). — Reinstate Monica Cellio, Dec 08 '16 at 16:27

In Chrome you need to use the jQuery focus function:

$(window).focus(function () {
    console.log('ative');
});

$(window).focus(function () {
    console.log('ative');
});
