This article mainly shares with you the code to realize the effect of cross coordinates following the mouse through JS. It can realize the effect of cross coordinates appearing according to the size of the browser window and following the movement of the mouse. It can also calculate the real-time coordinate number. Friends in need can refer to it. Let’s study. Hope it helps everyone.

Let’s first take a look at the rendering after operation:

The following is all the code after the editor’s test:

<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body style="margin: 0;">
 <p id="html"></p>
 <script type="text/javascript">
 //
 var ox = document.createElement(&#39;p&#39;);
 var oy = document.createElement(&#39;p&#39;);
 ox.style.width = &#39;100%&#39;;
 ox.style.height = &#39;1px&#39;;
 ox.style.backgroundColor = &#39;#ddd&#39;;
 ox.style.position = &#39;fixed&#39;;
 ox.style.left = 0;
 document.body.appendChild(ox);
 oy.style.height = &#39;100%&#39;;
 oy.style.width = &#39;1px&#39;;
 oy.style.backgroundColor = &#39;#ddd&#39;;
 oy.style.position = &#39;fixed&#39;;
 oy.style.top = 0;
 document.body.appendChild(oy);
 document.onmousemove = function(e){
 var e = e || event;
 var x = e.pageX;
 var y = e.pageY;
 ox.style.top = y + &#39;px&#39;;
 oy.style.left = x + &#39;px&#39;;
 document.getElementById(&#39;html&#39;). innerHTML = &#39;x : &#39; + x + &#39;<br/>y : &#39; + y;
 };
 </script>

</body>
</html>

During testing, you can adjust the code in JS according to your needs. X represents the abscissa and Y represents the ordinate.

JavaScript Frameworks: Powering Modern Web DevelopmentMay 02, 2025 am 12:04 AM

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.

The Relationship Between JavaScript, C , and BrowsersMay 01, 2025 am 12:06 AM

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 Streams with TypeScriptApr 30, 2025 am 08:22 AM

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

Python vs. JavaScript: Performance and Efficiency ConsiderationsApr 30, 2025 am 12:08 AM

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.

The 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?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 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 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.
