In front-end development, we often encounter the need to switch the display and hiding of elements based on user operations. The display attribute can achieve this function. In this article, we will use jQuery to implement the value switching effect of the display attribute. Next, let’s learn how to use jQuery to achieve this functionality.

First, introduce the jQuery library into the HTML file. You can use a CDN or import jQuery locally. Next, we create a simple HTML structure to demonstrate the switching effect:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Display 切换效果</title>
</head>
<body>
    <button id="toggleButton">切换显示</button>
    <div id="content" style="display: none;">
        这是要切换显示的内容。
    </div>

    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
    <script src="script.js"></script>
</body>
</html>

In the above code, we create a button element and a div element. Initially, the display attribute of the div element is none. , that is, the hidden state.

Next, we need to write jQuery code in the script.js file to switch the display and hidden state of the div element when the button is clicked:

$(document).ready(function() {
    $('#toggleButton').click(function() {
        $('#content').toggle();
    });
});

In the above code, we first use The $(document).ready() method ensures that the DOM is loaded before executing the code. Then, we listen to the click event of the button and use the toggle() method to switch the display and hidden state of the div element.

Now, when the user clicks the button, the div element will toggle between showing and hiding. This is a simple example of using jQuery to achieve the value switching effect of the display attribute. You can modify and expand the code according to actual needs to achieve richer interactive effects. Hope this article helps you!
