HomeWeb Front-endJS TutorialWithout AJAX and IFRAME, let's talk about the real ASP JS refreshless technology_javascript skills

What is being circulated on the Internet is that the ASP in > has no refresh. Adding an IFRAME and making JS cannot be called no refresh at all...
The code is not case-sensitive, please modify it yourself!
Full static no refresh idea:


//Countless new calls globally on the current page




//Example call one, direct call ASP
My database has //Example call two, event call AJAX.ASP My database has
entries



//AJAX.ASP code in Example 2
SET RS = CONN.EXECUTE(SQL_STR)
RESPONSE.WRITE "DOCUMENT.GETELEMENTBYID('COUNT'). VALUE = '"&RS("COUNT")&"'"
%>
///////////////////////////// ///////////////////////////////////////////////////// ///////////////////////////////////////////////////// ///////////////////////////////////
Part of the HTML code is omitted below, only the idea is explained
// Example 3 FORM form ONSUBMIT event calls AJAX.ASP

//This sentence is required






//Example 3 AJAX.ASP code
RESPONSE.WRITE "alert('"&request("a")&"');"//////Or write response.write "document.getelementbyid('id').innerhtml='Some html code';"
%>
/////////////////// ///////////////////////////////////////////////////// /////////////////////////////// Advantages: <script> //一系列JS调用 <BR>FUNCTION XX(FUN_NAME,PARAMETER_NAME,PARAMETER_VALUE)//参数自己设定 <BR>{ <BR>DOCMENT.SCRIPTS[0].SRC='AJAX.ASP?'+PARAMETER_NAME+'='+PARAMETER_VALUE;//参数以此类推 <BR>} <BR></script>The advantage of this no-refresh method compared to AJAX technology is that This method requires writing less code, is more concise, and develops faster. There is no need to write overly complex JS judgments. It also uses JS, but does not use DOM XML. It also has the advantage of cross-platform and can achieve the same advantages as AJAX. The user experience effect can be used simultaneously with AJAX. The code writing modes and processes for implementing different functions are almost the same, making it easier to improve code reusability. In fact, you only need to create 2 files to realize various functions of the website Disadvantages: Because this technology completely relies on JS to assign values ​​to the URL or COOKIES, and then passes parameters through the URL and cookies, but the size and length of the URL and cookies parameters are limited, so it cannot send a large amount of information like AJAX unless it is modeled after AJAX. Or use AJAX directly, but I believe I will find a better solution <script> <BR>function CHECK() <BR>{ <BR>alert('1'); <BR>//document.getElementByID("") <BR>document.scripts[0].src = "AJAX.ASP?a="+escape(document.getElementById('T1').value);//这里给第一个script.src赋值 <BR>alert(document.scripts[0].src);//查看测试地址是否正确 <BR>return false; <BR>} <BR></script>

The Origins of JavaScript: Exploring Its Implementation LanguageThe Origins of JavaScript: Exploring Its Implementation LanguageApr 29, 2025 am 12:51 AM

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

Behind the Scenes: What Language Powers JavaScript?Behind the Scenes: What Language Powers JavaScript?Apr 28, 2025 am 12:01 AM

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The Future of Python and JavaScript: Trends and PredictionsThe Future of Python and JavaScript: Trends and PredictionsApr 27, 2025 am 12:21 AM

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Python vs. JavaScript: Development Environments and ToolsPython vs. JavaScript: Development Environments and ToolsApr 26, 2025 am 12:09 AM

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Is JavaScript Written in C? Examining the EvidenceIs JavaScript Written in C? Examining the EvidenceApr 25, 2025 am 12:15 AM

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript's Role: Making the Web Interactive and DynamicJavaScript's Role: Making the Web Interactive and DynamicApr 24, 2025 am 12:12 AM

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.

C   and JavaScript: The Connection ExplainedC and JavaScript: The Connection ExplainedApr 23, 2025 am 12:07 AM

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

From Websites to Apps: The Diverse Applications of JavaScriptFrom Websites to Apps: The Diverse Applications of JavaScriptApr 22, 2025 am 12:02 AM

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

mPDF

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),
