jQuery find elements without data attribute

Question

How can I find all elements without a certain data-attribute?

I've tried:

$list.find('li:not([data-stuff])');

But it doesn't work.

Answer 1

jQuery stores data attributes in its cache, so you need to use filter:

var $li = $list.filter(function() {
    return $(this).data('stuff') != undefined;
});
// do something with $li...

Answer 2

I think what you're looking for is:

$list.find('li').not('li[data-stuff]').addClass('foo');

The addClass() is just there as a placeholder.
