Method 1: Using hasClass() method: The hasClass() is an inbuilt method in jQuery which check whether the elements with the specified class name exists or not. It returns a boolean value specifying whether the class exists in the element or not. This can be used to check for multiple classes. Syntax:

$('element').hasClass('className')

Example:

html

<!DOCTYPE html>
<html>
    
<head>
    <title>

    <script src=

    </script>
</head>

<body>
    <h1 style="color: green">

    </b>

    <p class="example-class">
        This element has "example-class".
    </p>

    <p>Does the element have class?
        <span class="output"></span>
    </p>

    <button onclick="checkForClass()">
        Click to check
    </button>
    
    <!-- Script to use hasClass() method to
        check the existence of class name -->
    <script type="text/javascript">
        function checkForClass() {
            classCheck = $('p').is('.example-class');
            document.querySelector('.output').textContent
                    = classCheck;
        }
    </script>
</body>

</html>

Output: check-class-hasClass

Method 2: Using is() method: This is similar to the above method and can be used to check more attributes if needed. The required element is selected and the class name is passed on like a CSS class selector. It returns a boolean value specifying whether the class exists in the element or not. This can be used to check for multiple classes. Syntax:

$('element').is('.className')

html
