]]> The toggleClass() method in jQuery is used to toggle (add or remove) one or more classes from the selected elements. If the specified class is present, it removes it; if not, it adds it. This method is useful for dynamically changing styles based on user interaction.

 

$(selector).toggleClass(className, [switch])

className: A string containing one or more class names to toggle.

switch (optional): A Boolean value (true to add the class, false to remove it).

Examples

Example 1: Basic toggleClass()

Toggles a class on a button click

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>toggleClass Example 1</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style>
        .highlight {
            background-color: yellow;
            font-weight: bold;
        }
    </style>
</head>
<body>

<p id="text">Click the button to toggle the highlight class.</p>
<button id="btn">Toggle Class</button>

<script>
    $(document).ready(function(){
        $("#btn").click(function(){
            $("#text").toggleClass("highlight");
        });
    });
</script>

</body>
</html>

Explanation:

  • When the button is clicked, the highlight class is toggled on the <p> element.
  • If the class is not present, it is added.
  • If already present, it is removed.

Example 2: Using toggleClass() with Multiple Classes

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>toggleClass Example 2</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style>
        .red { color: red; }
        .bold { font-weight: bold; }
    </style>
</head>
<body>

<p id="text">Click the button to toggle multiple classes.</p>
<button id="btn">Toggle Multiple Classes</button>

<script>
    $(document).ready(function(){
        $("#btn").click(function(){
            $("#text").toggleClass("red bold");
        });
    });
</script>

</body>
</html>

Explanation:

  • The toggleClass() method is used with multiple classes (red and bold).
  • Clicking the button adds or removes both classes together.

Example 3: Using toggleClass() with a Condition (Boolean)

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>toggleClass Example 3</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style>
        .large-text {
            font-size: 24px;
        }
    </style>
</head>
<body>

<p id="text">Click the buttons to add or remove the class.</p>
<button id="add">Add Class</button>
<button id="remove">Remove Class</button>

<script>
    $(document).ready(function(){
        $("#add").click(function(){
            $("#text").toggleClass("large-text", true); // Always adds class
        });

        $("#remove").click(function(){
            $("#text").toggleClass("large-text", false); // Always removes class
        });
    });
</script>

</body>
</html>

 

Explanation:

  • If true is passed, the class is always added.
  • If false is passed, the class is always removed.
  • This ensures no toggling, just explicit addition or removal.

Example 4: Using toggleClass() on Multiple Elements

 

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>toggleClass Example 4</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style>
        .selected {
            background-color: lightblue;
        }
    </style>
</head>
<body>

<ul>
    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
    <li>Item 4</li>
</ul>

<script>
    $(document).ready(function(){
        $("li").click(function(){
            $(this).toggleClass("selected");
        });
    });
</script>

</body>
</html>

Explanation:

  • Clicking on any <li> item will toggle the selected class for that specific item.
  • Each <li> works independently.

Example 5: ToggleClass() for Dark Mode

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>toggleClass Example 5</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style>
        body {
            transition: background 0.3s, color 0.3s;
        }
        .dark-mode {
            background-color: black;
            color: white;
        }
    </style>
</head>
<body>

<button id="toggle">Toggle Dark Mode</button>

<script>
    $(document).ready(function(){
        $("#toggle").click(function(){
            $("body").toggleClass("dark-mode");
        });
    });
</script>

</body>
</html>

Explanation:

  • Clicking the button toggles a “dark mode” effect by changing background and text color.
