Implementation method: 1. Use click() to bind the click event to the button element and set the processing function. The syntax is "button element.click(function(){});"; 2. In the processing function , use attr() to modify the image address, the syntax is "$("img").attr("src","new image address")".

jquery method to implement click-to-change pictures:
Implementation ideas:
-
Use click() to bind the click event to the button element and set the event processing function
In the processing function, use attr() to modify the image address (i.e. modify the img element src Attribute value)
Implementation code:Click the button to change the picture
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <script src="js/jquery-1.10.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("button").click(function() { $("img").attr("src","img/1.jpg"); }); }); </script> </head> <body> <img src="/static/imghwm/default1.png" data-src="img/3.jpg" class="lazy" style="max-width:90%" / alt="How to change pictures by clicking in jquery" ><br><br> <button>点击按钮,更换图片</button> </body> </html>
##Description:
Tag defines an image in an HTML page.
-
tags have two required attributes: src and alt.
- The src attribute of the
tag is required and specifies the URL of the image.

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

React is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability

The application of React in HTML improves the efficiency and flexibility of web development through componentization and virtual DOM. 1) React componentization idea breaks down the UI into reusable units to simplify management. 2) Virtual DOM optimization performance, minimize DOM operations through diffing algorithm. 3) JSX syntax allows writing HTML in JavaScript to improve development efficiency. 4) Use the useState hook to manage state and realize dynamic content updates. 5) Optimization strategies include using React.memo and useCallback to reduce unnecessary rendering.

React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.

The advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.

React is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.

React operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
