Troubles with HTML, CSS, and jQuery Double-Level Menu

After creating a simplified version of an HTML, CSS, jQuery navigation menu, I noticed that the submenu items were being considered part of the containing list item. This caused them to not function as intended when clicked because they were being treated with preventDefault(). To resolve this issue, I need to separate this behavior and allow the submenu links to be followed normally.

<html>
<head>
<style type="text/css">
    #content ul {margin:0;}
    #content ul li {float:left; background:#000; list-style:none;}
    #content ul li a {display:block; text-decoration:none; padding:10px 40px;}
    #content ul li ul {position:absolute; padding:0;}
    #content ul li ul li {float:none; background:#ccc;}
</style>
</head>

<body>
<div id="content">
    <ul>
        <li><a href="#">1</a></li>
        <li><a href="#">2</a></li>
        <li>
            <a href="#">3</a>
            <ul>
                <li><a href="#">A</a></li>
                <li><a href="#">B</a></li>
                <li><a href="#">C</a></li>
                <li><a href="#">D</a></li>
            </ul>
        </li>
        <li><a href="#">4</a></li>
    </ul>
</div>          
</body>
</html>

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<script type="text/javascript">
$('#content ul li').has('ul').click(function(e) {
    /* code to show/hide submenus */

    console.log(e);
    e.preventDefault();
});
</script>

Edit: My goal is to make all top level links and submenu links functional while only manipulating the behavior of the top-level list items with submenus.

Answer №1

To improve your code, adjust the initial selector to target the first child anchors within the 'content' element like so:

$('#content > ul > li > a').click(function(e) {
    /* Add code here to show/hide submenus */

    console.log(e);
    e.preventDefault();
});

Alternatively, you can add a CSS class to each anchor tag that needs the click event bound to it. This approach is cleaner and less likely to break with markup changes.

<div id="content">
    <ul>
        <li><a class="mainNav" href="#">1</a></li>
        <li><a class="mainNav" href="#">2</a></li>
        <li>
            <a class="mainNav" href="#">3</a>
            <ul>
                <li><a href="#">A</a></li>
                <li><a href="#">B</a></li>
                <li><a href="#">C</a></li>
                <li><a href="#">D</a></li>
            </ul>
        </li>
        <li><a class="mainNav" href="#">4</a></li>
    </ul>
</div> 

and

$("#content .mainNav").click(function(e) { e.preventDefault(); });

Update

Your original answer was very close. The problem lay in selecting all descendant li elements. I resolved this by adding the children selector to correct it.

$('#content ul li').has('ul').children('a').click(function(e) {
    /* Add code here to show/hide submenus */

    console.log(e);
    e.preventDefault();
});
