How to select an element that has focus on it with jQuery

How can you select an element that has current focus?

There is no :focus filter in jQuery, that is why we can use something like this:

$('input:focus').someFunction();

Really the best way to do it is to setup a handler for the onFocus event, and then set a variable to the ID of the element that has focus.

something like this:

var id;

$(":input").focus(function () {
     id = this.id;
});

$(document.activeElement) will return the currently focused element and is faster than using the pseudo selector :focus.

alert($("*:focus").attr("id"));

I use jQuery.

It will alert id of element is focusing.

I hope it useful for you.
