How to clone a block using jQuery ?

Last Updated : 24 Jul, 2024

In this article, we will learn how to clone a block using jQuery. The clone method in jQuery performs a deep copy of a set of matching elements. You can create a copy of the data as well as a copy of the event handlers. Whenever we are building a dynamic website then this method is very efficient and time-saving.

Syntax:

$(selector).clone(true|false)

Parameters Value:

True specifies that the event handlers should also be copied
False(Default) species that the event handlers should not be copied.

Example 1: In this example, we are not passing any value to the clone method.

HTML

<!DOCTYPE html>
<html>
<head>
    <script type="text/javascript" src=
        "https://code.jquery.com/jquery-1.12.0.min.js">
    </script>
    
    <style>
        #info {
            justify-content: center;
            width: 50%;
        }

        #container {
            border: 4px outset red;
            background-color: lightblue;
            justify-content: center;
            width: 50%;
        }

        #btn {
            background-color: #4CAF50;
            color: white;
            padding: 15px 32px;
            text-align: center;
            display: inline-block;
            font-size: 16px;
        }
    </style>

    <script>
        $(document).ready(function () {
            $("button").click(function () {
                $("#info").clone().appendTo("#container");
            });
        });
    </script>
</head>

<body>
    <div id="info">
        <h4>Clone() method</h4>
        
        <p>
            The .clone() method performs a deep 
            copy of the set of matched elements,
            meaning that it copies the matched 
            elements as well as all of their
            descendant elements and text nodes.
        </p>
    </div>

    <button id="btn"> Learn More</button>
    <br><br>
    
    <div id="container">
        <h3> Result </h3>
    </div>
</body>
</html>

Output:

Example 2: In this example, we are passing "true" value to the clone method that copies the event handlers also. Here we are changing the background color of the paragraph whenever the user clicks the paragraph. This will be copied as you can see in the output.
