Quiz

The element selector in jQuery is used to select and manipulate HTML elements based on their tag name.

Syntax

Following is the syntax of jQuery element selector −

$("element")

Parameters

The "element" specifies the element that you want to select (e.g., div, p, span).

Example 1

In the following example, we are using the jQuery elememt selector to select all the <p> elements −

<html>
<head>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script>
        $(document).ready(function() {
            $("button").click(function(){
                $('p').css("background-color", "yellow");
            })
        });
    </script>
</head>
<body>
    <p>Paragraph elememt 1.</p>
    <p>Paragraph elememt 2.</p>
    <div>Div element 1.</div>
    <p>Paragraph elememt 3.</p>
    <div>Div element 2.</div>
    <button>Click</button>
</body>
</html>

When we click the button, all the paragraph elememts will be selected and their background color will be changed to yellow.

Example 2

The following example selects the paragraph element and changes the text of that selected paragraph −

<html>
<head>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script>
        $(document).ready(function(){
            $("button").click(function(){
                $("p").text("Text changed!");
            })
        });
    </script>
</head>
<body>
    <p>This is a paragraph.</p>
    <button>Click</button>
</body>
</html>

After clicking the button, the paragraph text will change to "Text changed!".

Example 3

In this example, we are adding a class "highlight" to list items −

<html>
<head>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script>
        $(document).ready(function(){
            $("button").click(function(){
                $("li").addClass("highlight");
            })
        });
    </script>
    <style>
        .highlight {
            background-color: yellow;
        }
    </style>
</head>
<body>
    <ul>
        <li>Item 1</li>
        <li>Item 2</li>
        <li>Item 3</li>
        <button>Click</button>
    </ul>
</body>
</html>

After clicking the button, the all the list items will be highlighted with yellow color background.
