CSS
*{ margin: 0; padding: 0; background-color: #ccc; } p{ text-align: center; } #container{ width: 1130px; height: 350px; margin: 0 auto; border-right:1px solid #FF0000; border-bottom:1px solid #FF0000; overflow: hidden; position: relative; } #container img{ width:500px; height:350px; display: block; position: absolute; border-bottm:1px solid #FF0000; }
JS
//加载dom树 window.onload = function(){ //定义盒子 var box=document.getElementById('container'); //定义图片 var imgs=box.getElementsByTagName('img'); //图片宽度 var imgWidth = imgs[0].offsetWidth; //隐藏宽度 var exposeWidth = 210; //盒子宽度 var boxWidth = imgWidth + (imgs.length -1) * exposeWidth; box.style.width='px'; //设置每道门的初始位置 function SetImgsPos(){ for(var i = 1;i<imgs.length;i++){ imgs[i].style.left = imgWidth + exposeWidth*(i -1)+ 'px'; } } SetImgsPos(); //计算每道门应该移动的距离 var translate = imgWidth - exposeWidth; //为每道门绑定事件 for(var i=0;i<imgs.length;i++){ //使用立即调用的函数表达式,为了获得不同的i值 (function(i){ imgs[i].onmouseover = function(){ SetImgsPos(); //打开门 for(var j=1;j<=i;j++){ imgs[j].style.left = parseInt(imgs[j].style.left,10) - translate + 'px'; } } })(i); } }

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

The power of the JavaScript framework lies in simplifying development, improving user experience and application performance. When choosing a framework, consider: 1. Project size and complexity, 2. Team experience, 3. Ecosystem and community support.

Introduction I know you may find it strange, what exactly does JavaScript, C and browser have to do? They seem to be unrelated, but in fact, they play a very important role in modern web development. Today we will discuss the close connection between these three. Through this article, you will learn how JavaScript runs in the browser, the role of C in the browser engine, and how they work together to drive rendering and interaction of web pages. We all know the relationship between JavaScript and browser. JavaScript is the core language of front-end development. It runs directly in the browser, making web pages vivid and interesting. Have you ever wondered why JavaScr

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.
