jQuery: determine if a <li> contains a <ul>

Question

I have some HTML code that contains nested <ul> elements and I need to add a class 'parent' to each <li> element that contains a child <ul>. There could be more than one element contained directly withing a single <li>, e.g:

<li>
    <a>...</a>
    <span>...</span>
    <ul>...</ul>
</li>

All I need is to determine if a particular <li> contains a <ul> as a child element.

How would I go about this?

Answer 1

This will accomplish what you need:

$('li:has(> ul)').addClass('parent');

Answer 2

Changed the answer after re-reading the question:

$("li:has(ul)").addClass("parent");

Answer 3

Use the has selector.

$("li:has(ul)").addClass("parent")
