To achieve the effect of flipping the entire screen up and down:
js to be loaded
<script type="text/javascript" src="js/jquery-1.8.3.min.js"></script> <script type="text/javascript" src="js/jquery.mousewheel.js"></script>
The css style is as follows:
body{padding:0;margin:0; overflow:hidden }
ul{list-style:none;}
.content{width:100%;height100%;position:relative;top:0;}
.div_01,.div_02,.div_03,.div_04{width:100%;margin:0 auto; text-align: center;}
.div_01{background: #b20909;}
.div_02{background: #0941b2;}
.div_03{background: #2db209;}
.div_04{background: #b29c09;}
.left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;}
.left_fixed ul li{
background:#000;cursor:pointer;width:15px;height: 15px;
border-radius:15px;margin-bottom: 10px;
}
.left_fixed ul li.active{background:#fff;}
The jquery code is as follows:
var page=0;//翻屏变量，初始第一屏
var shakStaute = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象
$(function(){
var starttime = 0,
endtime = 0;
$("body").mousewheel(function(event, delta) {
starttime = new Date().getTime(); //记录翻屏的初始时间
if (delta < 0&& page>=0 && page<=$(".content .divsame").length-2) {
if (shakStaute>=0 &&(starttime == 0 || (endtime - starttime) <= -500)) { //在500ms内执行一次翻屏
shakStaute=1;
page++;
renderPage(page,true); //翻屏函数
endtime = new Date().getTime(); //记录翻屏的结束时间
}
} else if (delta>0 && page>=1 && shakStaute==1 && (starttime == 0 || (endtime - starttime) <= -500)) {
page--;
renderPage(page,true);
endtime = new Date().getTime();
}
});
var div_height=$(window).height();
$(".divsame").css({'height':div_height});
$(window).resize(function(){
div_height=$(window).height();
$(".divsame").css({'height':div_height});
$('.content').animate({top:-page*div_height }, 100);
});
$(".left_fixed ul li").on("click", function(){ //点击小导航也执行翻屏
var index = $(this).index();
if(index>0){
shakStaute==1;
}
page = index;
renderPage(page, true);
$(".left_fixed ul li").removeClass("active");
$(this).addClass("active");
return false;
});
function renderPage(pageNumber, isScroll){
if (isScroll){
$('.content').animate({top:-pageNumber*div_height }, 'slow');
$(".left_fixed ul li").removeClass("active");
$(".left_fixed ul li").eq(pageNumber).addClass("active");
}
return;
}
})
It also responds in real time.
Let’s look at another example
Pay attention to the js loaded in the head, the jquery library, and the index.js that mousewheel.js has implemented
<!doctype html>
<html>
<head>

<style>

ul{list-style:none;}

.div_01{background: #b20909;}

.left_fixed{position:fixed;width:15px; height:100px; left:100px;top:200px;z-index:999;}

jquery code is as follows (index.js):

var s = 0; //该变量作用是鼠标滑轮一直向下或者向上滑动时出现抖动现象
$(function(){
var starttime = 0,

} else if (delta > 0&& i>=1&&s==1&& (starttime == 0 || (endtime - starttime) <= -500)) {

//console.log(i);
renderPage(i,true);
endtime = new Date().getTime();
}
});
var div_height=$(window).height();
$(".div_01,.div_02,.div_03,.div_04").css({'height':div_height});
$(window).resize(function(){
var div_height=$(window).height();
$(".div_01,.div_02,.div_03,.div_04").css({'height':div_height});
});
function renderPage(pageNumber, isScroll){
if (isScroll){

Node.js Streams with TypeScriptApr 30, 2025 am 08:22 AMNode.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
Python vs. JavaScript: Performance and Efficiency ConsiderationsApr 30, 2025 am 12:08 AMThe 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.
The Origins of JavaScript: Exploring Its Implementation LanguageApr 29, 2025 am 12:51 AMJavaScript 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?Apr 28, 2025 am 12:01 AMJavaScript 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 PredictionsApr 27, 2025 am 12:21 AMThe 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 ToolsApr 26, 2025 am 12:09 AMBoth 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 EvidenceApr 25, 2025 am 12:15 AMYes, 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 DynamicApr 24, 2025 am 12:12 AMJavaScript 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.
