This article mainly shares with you how to create a simple publishing function in js, mainly in the form of code. I hope it can help everyone.
The code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>demo</title>
<link href="https://cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.css" rel="stylesheet">
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<style type="text/css">
.showMessage{
background-color: #ccc;
margin-top: 12px;
padding:20px;
border-radius: 8px;
}
</style>
</head>
<body>
<p class="container" style="padding-top:50px;">
<p class="col-md-3 message">
<input type="" class="form-control" name="" id="inpText" placeholder="请输入标题">
<textarea class="form-control" rows="10" style="margin-top: 20px" id="textaText" placeholder="请输入内容"></textarea>
<button class="btn btn-primary" style="margin-top:20px " id="button01">提交</button>
</p>
<p class="col-md-9 mainMessage" id="right">
<p class="showMessage">
<i>模板</i>
<h3 id="标题">标题</h3>
<p class="MC">这里是内容</p>
</p>
</p>
</p>
</body>
</html>js:
<script type="text/javascript">
window.onload = function(){
$('#button01').click(function(){
var inpText = document.getElementById('inpText').value;//获取值
var textaText = document.getElementById('textaText').value;//获取值
var right = document.getElementById('right');
var p = document.createElement('p');//创建一个p
p.className = 'showMessage';
var h3 = document.createElement('h3');//创建一个h3
h3.className = "MT";//设置类名
p.appendChild(h3);//将h3添加到p
h3.innerHTML = inpText;
var p = document.createElement('p');//创建一个p
p.innerHTML = textaText;
p.className = "MC";
p.appendChild(p);
right.appendChild(p);
})
}
</script>Observe the above js part:
var inpText = document.getElementById('inpText').value;//获取值 var textaText = document.getElementById('textaText').value;//获取值
These two lines of code cannot be placed in front of the following code
$('#button01').click(function(){}Assume I put it in front. After the page is loaded, I will start to execute the following two lines of code. I will find that the obtained value is empty, so I need to put it in the click function. Only when the button is clicked will I start to obtain the input and textarea. value. (I assume here that you did not assign values to these two tags before writing the code);
var inpText = document.getElementById('inpText').value;//获取值 var textaText = document.getElementById('textaText').value;//获取值
If there are other three tags created:
var p = document.createElement('p');//创建一个p var h3 = document.createElement('h3');//创建一个h3 var p = document.createElement('p');//创建一个p
must be added to the HTML node among.
p.appendChild(h3);//将h3添加到p p.appendChild(p); right.appendChild(p);
In addition, you can also do a post-release review of additions, deletions, and modifications. Use your imagination. Finally~Thank you for reading this article~

JavaScript in Action: Real-World Examples and ProjectsApr 19, 2025 am 12:13 AMJavaScript'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 AMThe 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 AMUnderstanding 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 AMPython 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 AMPython 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 AMThe 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 AMDifferent 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 AMJavaScript'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.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
