Find child elements by missing attribute with jQuery

Question

Finding elements by attribute in jQuery is simple:

$(parentElement).find('[attribute]');

How do you find elements, that don't have a certain attribute?

Answer 1

That's why the :not() is made for.

Try,

$(parentElement).find(':not([attribute])');

Answer 2

You can use :not although filter is most likely faster:

$(parentElement).filter(function() {
    return !$(this).attr('attribute');
});
