Testing :focus on multiple elements with is(), has(), filter(), ...

Demo: I select multiple elements with .text-block selector. I want to check if ANY element has the focus (one of them has when executing this code), here are the results :

$('.text-block').is(":focus") // returns false
$('.text-block').has(":focus") // returns empty object array
$('.text-block').filter(":focus") // returns empty object array on FF,returns the focused element on chrome
$('.text-block:focus') // returns the focused element

You can see that only $('.text-block:focus') works for both FF and chrome. The problem is that when you have the elements as a variable, $textBlocks, you can't use the version that works anymore.

Here is the jsfiddle test case:


Try to focus on one of the divs, and you'll notice that on FF and Chrome, the result is different for filter() for example.

and forgot to mention that result for .is(":focus") is also different in the two browsers

Duplicate of #13041.
Some of this is misunderstanding of the APIs, and the rest is a Firefox inconsistency (not sure if it can be called a bug).

$('.text-block').is(":focus") returns false

That will only check the first element, per .is().

$('.text-block').has(":focus") returns empty object array

That is incorrect use of .has(), which checks whether any descendant elements match the selector.

$('.text-block').filter(":focus") returns empty object array on FF,returns the focused element on chrome

That is duplicate of #13041.
