is it possible to check if an element is focused?

i tryed:

 <a href="#"></a>
    $('a').is(':focused');

but it won't work.

Also i would like to understand if is possible to get the last focused document element attr class:

var last_focused_class = document.lastFocusedElement.class;

for example

  • have you tried is(':focus') (docs). – David Thomas Commented May 16, 2013 at 17:07

Reset to default 14

You were close, to test for focus:

$('a').is(':focus');

Not sure about how to get the last focused element, you may have to design a hack for it...something like:

var lastFocusedClass;
$(document).on('focus', '*', function() {
    lastFocusedClass = $(this).attr("class");
});

In my case this works... $("*:focus")

You can get id,name,value etc.And check if this is the element you are looking for.

var checkValue = $("*:focus").attr("...");
