What packages need to be imported when using jQuery?

jQuery is a popular JavaScript library that helps developers manipulate HTML elements, handle events, and perform animations more efficiently. In order to use jQuery, developers need to import the relevant jQuery package in the HTML file. The following is a specific code example of how to import jQuery:

1. Download jQuery package: First, you need to download the latest jQuery package from the official website (https://jquery.com/). Select a development or production version and download it to your project folder. You can also choose to use a CDN to import the jQuery library.
2. Import jQuery package: In the tag of the HTML file, import the jQuery package with the following code example:

<script src="path/to/jquery.min.js"></script>

In this example, Replace path/to/jquery.min.js with the exact path where the jQuery package is stored. If you are using a CDN, you can import it through the following code:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>

In this way, the jQuery library is successfully imported. In the subsequent development process, you can use jQuery methods and functions.

3. Using jQuery Example:

Once you have successfully imported the jQuery library, you can use it in the following ways:

$(document).ready(function(){
    // 在页面加载完毕后执行以下代码
    $("button").click(function(){
        // 当按钮被点击时执行以下代码
        $("p").toggle();
    });
});

In this example, We used $(document).ready() to ensure that the page is fully loaded before executing the JavaScript code, and then used $("button").click() to add the button Click event to hide or show paragraph elements when the button is clicked.
