How to implement the fixed effect of sliding the blog sidebar module following the scroll bar (js jquery, etc.)_javascript skills
When the content of a page is very long, the sidebar columns may appear too short. When the window slides to the lower position, the opportunity to display the content is lost on the side. Many news and information websites, such as Sina, NetEase, CSDN, etc., will use a fixed small pop-up window in the lower right corner of the sidebar to provide more content display methods, but this is not suitable for blogs and web2.0 style websites.
Nowadays, many independent blogs and websites, such as Renren, etc., use the effect of having the sidebar module slide with the scroll bar and its position is fixed. That is, when a page is very long, set the side column content to follow the scroll bar. This effect is suitable for websites with many comments and long content. Zhiwen Studio has investigated several implementation methods of similar functions and excerpted them for reference.
Reference 1. Special effects to increase pageviews: sidebar follows scroll bar
Source: Lu Songsong’s Blog
http://lusongsong.com/reed/453.html
The code is as follows:
CSS part:
/*Sidebar follows* /
#box{float:left; position:relative;width:250px;}
.div1{width:250px;}
.div2{position:fixed;_position:absolute;top:0;z -index:250;}
Note: The width of the sidebar of each website is different. You can adjust the width of div1 according to the width of your web page. Mine is width:250px;. Just add this code to your CSS file.
JS part:
JavaScript code
//Sidebar Follow
(function(){
var oDiv=document.getElementById("float");
var H=0,iE6;
var Y=oDiv;
while(Y){H =Y .offsetTop;Y=Y.offsetParent};
iE6=window.ActiveXObject&&!window.XMLHttpRequest;
if(!iE6){
window.onscroll=function()
{
var s=document.body.scrollTop||document.documentElement.scrollTop; ";}}
Put it in any JS file, for example, I put it in the util.js file.
Web page code part:
Copy code
The code is as follows:
Note: Article lists and affiliate ads can be placed here. In short, it is a good way to increase click-through rates. Z-blog users can add this code to the sidebar of single.html.
Special Tip: This code is tried with any CMS system, but the special effect cannot be implemented under IE6. Other browsers are fine. At the same time, the rest of the sidebar should be called using static files. Using JS to call the column will cause code overlap. , calling affiliate advertising is no problem.

The steps are as follows:
1. Add some class flags to each module of the sidebar If your sidebar already has these class flags to distinguish them, just use them without adding them. Adding ID can also achieve the effect, but the w3c standard does not allow multiple identical IDs to appear on the same page, so it is best to use class style.
2. Add the following code to any js file on the website page:
JavaScript code
Copy code
The code is as follows:
var rollStart = $('.Statistics'), //Start to follow when scrolling to this block
rollOut = $('.WidgetMeta,.Statistics'); //After hiding rollStart Blocks
rollSet = $('.RRPosts,.TagsCloud'); //Add follow-up block before rollStart
rollStart.before('');
var offset = rollStart.offset(),objWindow = $(window),rollBox = rollStart.prev();
objWindow.scroll(function() {
if (objWindow.scrollTop() > offset.top){
if(rollBox.html(null)){
rollSet.clone().prependTo(' .rollbox');
}
rollOut.fadeOut();
rollBox.show().stop().animate({top:0,paddingTop:10},400);
} else {
rollOut.fadeIn();
rollBox.hide().stop().animate({top:0},400);
}
});
Note: The content in the scroll area cannot be too long, otherwise infinite drop-down will occur.
Reference 3. JQUERY SCROLL FOLLOW
This is a plug-in, and the steps to add it are very simple. Download the compressed package and extract it to the website directory, and then follow the steps.

The sidebar module slides with the window (sample page)
Source: http://www.mb-wx.com/common/msay.js
This code comes from Muben Wuxin’s blog (pjblog) , the principle is very simple, that is, when the window reaches the specified module position, it starts to judge its distance from the top and adjust it. This code is used in the sidebar of Zhiwen Studio blog.
JavaScript code
//Sidebar The module slides with the window.
jQuery(document).ready(function($) {
$(function() { (window),
offset = $sidebar.offset(),
topPadding = 0;
$window.scroll(function() {
if ($window.scrollTop() > offset. top) {
$sidebar.stop().animate({
marginTop: $window.scrollTop() - offset.top topPadding
});
} else {
$sidebar. stop().animate({
marginTop: 0
});
}
});
});
});

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.

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.

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 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.

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.

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 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.
