JQuery is()

The jQuery is() method checks whether the selected element matches a specified selector. It returns true if the element matches the selector, and false if it does not.

Syntax

$(selector).is(filter)

The selector is the element or elements to be checked, and the filter is the selector or elements to be checked against.

Use

The is() method is used to check if an element matches a specific selector or set of selectors. It can be particularly useful when working with event handlers and conditional statements.

Example

Here is an example of using the is() method to check whether a selected element is a div:

<!DOCTYPE html>
<html>
<head>
    <title>is() Method Example</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <style type="text/css">
        .container {
            background: #ccc;
            padding: 10px;
        }
    </style>
</head>
<body>
    <div class="container">
        <p>This is a paragraph inside a div container.</p>
    </div>
    <script type="text/javascript">
        if ( $("div").is(".container") ) {
            alert("This element is a div with class 'container'");
        }
    </script>
</body>
</html>
Try Playground

In this example, the is() method is used to check whether the selected div element has the class container. If it does, an alert will be displayed.

Summary

The is() method in jQuery is a useful tool for checking whether an element matches a specific selector or set of selectors. It can be used in a variety of situations, including event handlers and conditional statements. With its simple syntax and flexibility, the is() method is a powerful tool for jQuery users.
