javascript - How can I select an element which does not contain a certain child element?

Question

<div class="test">
 <div class="example"></div>
</div>

<div class="test">
</div>

How can I apply jQuery to an element with the class test only if it doesn't contain a child element with the class example?

Answer 1

$('.test:not(:has(.example))')

-or-

$('.test').not(':has(.example)')
