Let’s take a look at how other friends achieved it

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

<title>oec2003</title>

<script language="JavaScript" type="text/JavaScript">

<!--

function toggle(targetid){

  if (document.getElementById){

    target=document.getElementById(targetid);

      if (target.style.display=="block"){

        target.style.display="none";

      } else {

        target.style.display="block";

      }

  }

}

-->

</script>

<style type="text/css">

<!--

#div1{

background-color:#000000;

height:400px;

width:400px;

display:none;

}

-->

</style>

</head>



<body>

<input type="button" id="butn" value="显示/隐藏" onclick="toggle('div1')" />

<center>

<div id="div1"></div></center>

居中的DIV

</body>

</html>

Example 3:

Let’s look at the simplest example first, which can show and hide layers

<div id="text"></div><input type="button" onclick="display('text')" />
function $_(id){ 
return document.getElementById(id);
};
function display(x){ 
$(x).style.display=($(x).style.display=="none")&#63;"":"none";
};

The following is a closed layer. In fact, the principle is the same, but an effect is added.

.wang ul{ width:100px; height:100px; margin:0 auto;}  
</style>
</head>

<script type="text/javascript">
function dianji(){
  x=document.getElementById("xian");
  x.style.display="block";
  return false;
  }
  function guanbi(name){ 
  var c=document.getElementById("wangyan").value;
  if(c==3){
    
  x.style.display='none';
  return false;
  }  
  }
</script>
</body>
</html>

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.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
