This article mainly introduces the guessing game based on vue components in detail. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.
The example in this article shares the specific code of the vue number guessing game for your reference. The specific content is as follows
##
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>vue组件猜数字游戏</title> <script src="js/vue.js"></script> </head> <body> <p id="container"> <p>{{msg}}</p> <my-game></my-game> </p> <script> /* *创建一个组件,my-game: 猜数字大小。 组件:一个input和一个p构成 当组件准备挂载的时候,初始化一个随机数, 在input取输入的时候, 如果输入的数字小了,在p显示:输入的太小了; 如果输入的数字大了,在p显示:输入的太大了; 否则就提示输入正确。 * */ //完成组件的创建 Vue.component("my-game",{ data:function(){ return { randomNum:0, myInput:0, result:"" } }, template:` <p> <input type="text" v-model.number="myInput"/> <br> <p>{{result}}</p> </p> `, beforeMount: function () { //创建一个100以内的随机的整数 var num = Math.floor(Math.random()*100); console.log(num); this.randomNum = num; }, //当数据改变时执行的操作 watch:{ myInput:function(){ if(this.myInput==this.randomNum){ this.result = "恭喜:猜对了"; }else if(this.myInput>this.randomNum){ this.result = "啊哦!猜大了"; }else{ this.result = "啊哦!猜小了"; } } } }) new Vue({ el:"#container", data:{ msg:"Hello VueJs" } }) </script> </body> </html>Related recommendations:

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.
