Hello, OK I have this code. Now I want a red background added in Item 3 and Item 4 only (not in its children). But its not working. What I am doing wrong?

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Navigation</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

<style>
.bg {
	background: red;
}
</style>

<script>
$(document).ready (function () {
	$("div ul li").has("ul").parent("li").addClass("bg");
});
</script>

</head>
<body>

<div>
<ul>
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a>
	<ul>
	<li><a href="#">Item 3.1</a></li>
	<li><a href="#">Item 3.2</a></li>
	<li><a href="#">Item 3.3</a></li>
	</ul>
</li>
<li><a href="#">Item 4</a>
	<ul>
	<li><a href="#">Item 4.1</a></li>
	<li><a href="#">Item 4.2</a></li>
	<li><a href="#">Item 4.3</a></li>
	</ul>
</li>
</ul>
</div>

</body>
</html>

Edit: I shouldn’t have used the parent(“li”). But then how to achieve what I want ?

add the class to the <a>, not the <li>.

3 
$("div ul li").has("ul").parent("li a").addClass("bg");

didn’t worked.

4

obviously. this is not a working filter expression for parent(). <a> is not even a parent of <ul>.

How about:

$("div ul li").has("ul").addClass("bg");

Then use css:

.bg > a {
	background: red;
}

Or with no js use css only:

ul li a:first-child:nth-last-child(2){background:red}

IE9+ only (and all other modern browsers),
