jQuery is a framework based on JavaScript. It is widely used because of its simplicity and convenience. Do you know how to create and add nodes with jQuery? This article will tell you how to create nodes and add nodes with jQuery. It has certain reference value. Interested friends can refer to it.

Note: When using jQuery, you must first introduce the jQuery file

Method 1, append() method

append() can add nodes and add them at the end of the selected element

Example: Add dragon fruit at the end of the unordered list This item

Description: First create a

element, then find the parent node of the

element, and finally add this node to the

<!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8">
  <title></title>
  <script src="js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
 </head>
 <body>
  <ul>
   <li>榴莲</li>
   <li>西瓜</li>
   <li>橘子</li>
   <li>雪梨</li>
  </ul>
  <button id="btn">点击添加</button>
 </body>
 <script type="text/javascript">
  $(document).ready(function(){
      $("#btn").click(function(){
          $("ul").append(" <li>火龙果</li>");
      });      
  });
 </script>
</html>

The effect is as shown in the figure:

Method 2, prepend() method

The prepend() method can add nodes, which are added to the beginning of the selected elements

Example: Add dragon fruit as the first element to the unordered list

The code is as follows:

<!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8">
  <title></title>
  <script src="js/jquery.min.js" type="text/javascript" charset="utf-8"></script>
 </head>
 <body>
  <ul>
   <li>榴莲</li>
   <li>西瓜</li>
   <li>橘子</li>
   <li>雪梨</li>
  </ul>
  <button id="btn">点击添加</button>
 </body>
 <script type="text/javascript">
  $(document).ready(function(){
      $("#btn").click(function(){
          $("ul").prepend(" <li>火龙果</li>");
      });      
  });
 </script>
</html>

The effect is as shown in the figure:

In addition, there are after() method and before() method. The after() method in jQuery inserts content after the selected element, and the before() method inserts content before the selected element. The essence is similar to append() and prepend(), and will not be demonstrated here.

The above introduces the method of creating nodes and adding nodes in jQuery. It is relatively simple. Interested friends can try the after() method and before() method by themselves. I hope you can master it as soon as possible. For more related tutorials, please visit jQuery Video Tutorial

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AM

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

JavaScript and the Web: Core Functionality and Use CasesApr 18, 2025 am 12:19 AM

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding the JavaScript Engine: Implementation DetailsApr 17, 2025 am 12:05 AM

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python vs. JavaScript: The Learning Curve and Ease of UseApr 16, 2025 am 12:12 AM

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python vs. JavaScript: Community, Libraries, and ResourcesApr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

From C/C to JavaScript: How It All WorksApr 14, 2025 am 12:05 AM

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

JavaScript Engines: Comparing ImplementationsApr 13, 2025 am 12:05 AM

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

Beyond the Browser: JavaScript in the Real WorldApr 12, 2025 am 12:06 AM

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
