Sample code of encapsulated function for motion buffering effect
I used to write a lot of motion functions, but later I found a way to encapsulate them. (motion buffering). This article mainly introduces the encapsulation function of JS to achieve motion buffering effect, involving JavaScript time function and numerical operation related operation skills. Friends in need can refer to it, I hope it can help you.
/*
物体多属性同时运动的函数
obj：运动的物体
oTarget：对象，属性名为运动的样式名，属性值为样式运动的终点值
ratio：速度的系数
*/
function bufferMove(obj, oTarget, fn,ratio = 8) {
clearInterval(obj.iTimer);
obj.iTimer = setInterval(function () {
// 此处设定开关bBtn，假设所有的属性均已运动完毕true
var bBtn = true;
for(var sAttr in oTarget){
// 获取当前值，此处兼容透明度的变化
if(sAttr === 'opacity') {
var iCur = parseFloat(getStyle(obj, sAttr) * 100);
} else {
var iCur = parseInt(getStyle(obj, sAttr));
}
// 计算速度，此处可判定方向，如向左或向右，先透明后出现或先出现后透明等
var iSpeed = (oTarget[sAttr] - iCur) / ratio;
iSpeed = iSpeed > 0 ? Math.ceil(iSpeed) : Math.floor(iSpeed);
// 计算下一次的值
var iNext = iCur + iSpeed;
// 赋值给对应样式
if(sAttr ==='opacity') {
obj.style.opacity = iNext / 100;
obj.style.filter = 'alpha(opacity=' + iNext +')';
} else {
obj.style[sAttr] = iNext + 'px';
}
// 清除定时器，当前的位置和终点值是否相等，相等则说明结束
if(iNext !== oTarget[sAttr]) {
bBtn = false;
}
}
// 如果bBtn的值为true，则说明所有的属性均已运动完毕，回调函数fn()
if(bBtn) {
clearInterval(obj.iTimer);
if(fn){
fn();
}
}
}, 50);
}The above encapsulated functions can also be used for single attributes and multi-style movements, such as:
bufferMove(obj,{"left":200,"width":400,"opacity":80},fn,8);That’s it .

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.

JavaScript: Exploring the Versatility of a Web LanguageApr 11, 2025 am 12:01 AMJavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

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),
