How to make pictures rotate in jquery
Image rotation is a common effect in web design, which can make web pages more vivid and interesting. In front-end development, we often use jQuery to achieve this effect. This article will introduce how to use jQuery to realize image rotation.
1. Make a picture
First you need to prepare a picture to be rotated. It can be a simple circle, or a complex picture with text and patterns. This article will take a simple circle diagram as an example.
2. Write HTML and CSS code
Put the image into the HTML file, as shown below:
<div class="rotate"> <img src="circle.png"> </div>
In order to make the image rotate, we need to modify its CSS style. The specific modification method is as follows:
.rotate {
display: inline-block;
position: relative;
margin: 50px;
}
.rotate img {
position: absolute;
top: 0;
left: 0;
width: 200px;
height: 200px;
}The main purpose of the above modification is to set the picture and its containing box to relative and absolute positioning, and at the same time set the width, height and position of the picture.
3. Use jQuery to achieve image rotation
Next, we will use jQuery to achieve the image rotation effect. There is a very convenient function animate() in jQuery, which can be used to achieve a variety of animation effects, including rotation. Here, we will use this function to implement image rotation.
The specific code is as follows:
$(document).ready(function() {
$(".rotate img").animate({
rotate: '360deg'
},{
duration: 2000,
step: function(now, fx) {
$(this).css('-webkit-transform','rotate('+now+'deg)');
$(this).css('-moz-transform','rotate('+now+'deg)');
$(this).css('transform','rotate('+now+'deg)');
}
});
}); The above code does the following things:
- After the page is loaded, look for the class ".rotate img" element and rotate it 360 degrees using the animate() function.
- In the animate() function, the animation transition duration is set to 2000 milliseconds, which is 2 seconds.
- In the step callback function, the element is rotated according to the current rotation angle, and some browser manufacturer prefixes are added to ensure the compatibility of the animation effect in various browsers.
Run the above code to make the picture rotate!
4. Complete code example
The following is the complete HTML and jQuery code:
HTML code:
<html> <head> <meta charset="UTF-8"> <title>jQuery图片自转示例</title> <link rel="stylesheet" href="style.css"> </head> <body> <div class="rotate"> <img src="circle.png"> </div> <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script> <script src="script.js"></script> </body> </html>
CSS code:
.rotate {
display: inline-block;
position: relative;
margin: 50px;
}
.rotate img {
position: absolute;
top: 0;
left: 0;
width: 200px;
height: 200px;
}jQuery code:
$(document).ready(function() {
$(".rotate img").animate({
rotate: '360deg'
},{
duration: 2000,
step: function(now, fx) {
$(this).css('-webkit-transform','rotate('+now+'deg)');
$(this).css('-moz-transform','rotate('+now+'deg)');
$(this).css('transform','rotate('+now+'deg)');
}
});
}); Summary
Through the above steps, you can use jQuery to achieve the image rotation effect on the web page. In addition, jQuery can also be used to implement various other animation effects, such as fade in and fade out, sliding, etc., which can be used to enhance the interactivity and beauty of web pages.

Vue 2's reactivity system struggles with direct array index setting, length modification, and object property addition/deletion. Developers can use Vue's mutation methods and Vue.set() to ensure reactivity.
React Components: Creating Reusable Elements in HTML
Apr 08, 2025 pm 05:53 PM
React components can be defined by functions or classes, encapsulating UI logic and accepting input data through props. 1) Define components: Use functions or classes to return React elements. 2) Rendering component: React calls render method or executes function component. 3) Multiplexing components: pass data through props to build a complex UI. The lifecycle approach of components allows logic to be executed at different stages, improving development efficiency and code maintainability.
React and the Frontend: Building Interactive Experiences
Apr 11, 2025 am 12:02 AM
React is the preferred tool for building interactive front-end experiences. 1) React simplifies UI development through componentization and virtual DOM. 2) Components are divided into function components and class components. Function components are simpler and class components provide more life cycle methods. 3) The working principle of React relies on virtual DOM and reconciliation algorithm to improve performance. 4) State management uses useState or this.state, and life cycle methods such as componentDidMount are used for specific logic. 5) Basic usage includes creating components and managing state, and advanced usage involves custom hooks and performance optimization. 6) Common errors include improper status updates and performance issues, debugging skills include using ReactDevTools and Excellent

Functional components in Vue.js are stateless, lightweight, and lack lifecycle hooks, ideal for rendering pure data and optimizing performance. They differ from stateful components by not having state or reactivity, using render functions directly, a
React vs. Backend Frameworks: A Comparison
Apr 13, 2025 am 12:06 AM
React is a front-end framework for building user interfaces; a back-end framework is used to build server-side applications. React provides componentized and efficient UI updates, and the backend framework provides a complete backend service solution. When choosing a technology stack, project requirements, team skills, and scalability should be considered.
