Solution to the failure of jquery control: 1. Open the corresponding js code file; 2. Pass "$("#xxx").show("slow",function(){$(this).css ("display","block")});" just do it.

What should I do if the jquery control fails?
About jquery's problem of hiding and displaying controls
Generally, if we want to dynamically display or hide html jsp controls, we can use jquery's own methods
$("#id").hide(); $("#id").show();
But sometimes when we dynamically control the hiding or display of elements in the control, failure may occur.
For example, if th tr in a div or li in ul hide the div ul, it may not be possible to hide the controls inside, so this will fail.
Solution:
$("#xxx").hide("slow",function(){$(this).css("display","none")}); $("#xxx").show("slow",function(){$(this).css("display","block")});
For the slow function, I looked at the source code and found that it is a speed control for hiding or displaying.
Optional parameters include fast and _default.
As for the choice, it depends on your own preferences.

To integrate React into HTML, follow these steps: 1. Introduce React and ReactDOM in HTML files. 2. Define a React component. 3. Render the component into HTML elements using ReactDOM. Through these steps, static HTML pages can be transformed into dynamic, interactive experiences.

React’s popularity includes its performance optimization, component reuse and a rich ecosystem. 1. Performance optimization achieves efficient updates through virtual DOM and diffing mechanisms. 2. Component Reuse Reduces duplicate code by reusable components. 3. Rich ecosystem and one-way data flow enhance the development experience.

React is the tool of choice for building dynamic and interactive user interfaces. 1) Componentization and JSX make UI splitting and reusing simple. 2) State management is implemented through the useState hook to trigger UI updates. 3) The event processing mechanism responds to user interaction and improves user experience.

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.

The relationship between HTML and React is the core of front-end development, and they jointly build the user interface of modern web applications. 1) HTML defines the content structure and semantics, and React builds a dynamic interface through componentization. 2) React components use JSX syntax to embed HTML to achieve intelligent rendering. 3) Component life cycle manages HTML rendering and updates dynamically according to state and attributes. 4) Use components to optimize HTML structure and improve maintainability. 5) Performance optimization includes avoiding unnecessary rendering, using key attributes, and keeping the component single responsibility.

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

React is a JavaScript library for building user interfaces, with its core components and state management. 1) Simplify UI development through componentization and state management. 2) The working principle includes reconciliation and rendering, and optimization can be implemented through React.memo and useMemo. 3) The basic usage is to create and render components, and the advanced usage includes using Hooks and ContextAPI. 4) Common errors such as improper status update, you can use ReactDevTools to debug. 5) Performance optimization includes using React.memo, virtualization lists and CodeSplitting, and keeping code readable and maintainable is best practice.

React combines JSX and HTML to improve user experience. 1) JSX embeds HTML to make development more intuitive. 2) The virtual DOM mechanism optimizes performance and reduces DOM operations. 3) Component-based management UI to improve maintainability. 4) State management and event processing enhance interactivity.
