This article mainly introduces the relevant information about javascript to determine whether the user has operated the page. I hope this article can help everyone. Friends in need can refer to
javascript to determine whether the user has operated the page.
Use js to determine whether the user has operated the page. All we have to do is organize our ideas.
1. Ideas
Whether the user has an operation interface, we can consider whether the page triggers events within the specified time. For example, whether the user clicked, pressed a button, or rolled the mouse wheel. Did the user move the mouse, etc. If the user does not perform these operations, then we can roughly think that the user does not operate the page. We can give a timer. To record whether the user triggers these events within the specified time. I will post the code directly. I will not explain the specific meaning of the code. The idea is roughly like this.
2. Code Demonstration
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>js判断用户有没有操作页面</title> </head> <body> <script> window.onload = function (){ (function($){ funObj = { timeUserFun:'timeUserFun', } $[funObj.timeUserFun] = function(time){ var time = time || 2; var userTime = time*60; var objTime = { init:0, time:function(){ objTime.init += 1; if(objTime.init == userTime){ console.log(111) // 用户到达未操作事件 做一些处理 } }, eventFun:function(){ clearInterval(testUser); objTime.init = 0; testUser = setInterval(objTime.time,1000); } } var testUser = setInterval(objTime.time,1000); var body = document.querySelector('html'); body.addEventListener("click",objTime.eventFun); body.addEventListener("keydown",objTime.eventFun); body.addEventListener("mousemove",objTime.eventFun); body.addEventListener("mousewheel",objTime.eventFun); } })(window) // 直接调用 参数代表分钟数,可以有一位小数; timeUserFun(0.1); } </script> </body> </html><!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>js判断用户有没有操作页面</title> </head> <body> <script> window.onload = function (){ (function($){ funObj = { timeUserFun:'timeUserFun', } $[funObj.timeUserFun] = function(time){ var time = time || 2; var userTime = time*60; var objTime = { init:0, time:function(){ objTime.init += 1; if(objTime.init == userTime){ console.log(111) // 用户到达未操作事件 做一些处理 } }, eventFun:function(){ clearInterval(testUser); objTime.init = 0; testUser = setInterval(objTime.time,1000); } } var testUser = setInterval(objTime.time,1000); var body = document.querySelector('html'); body.addEventListener("click",objTime.eventFun); body.addEventListener("keydown",objTime.eventFun); body.addEventListener("mousemove",objTime.eventFun); body.addEventListener("mousewheel",objTime.eventFun); } })(window) // 直接调用 参数代表分钟数,可以有一位小数; timeUserFun(0.1); } </script> </body> </html>

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.

C and JavaScript achieve interoperability through WebAssembly. 1) C code is compiled into WebAssembly module and introduced into JavaScript environment to enhance computing power. 2) In game development, C handles physics engines and graphics rendering, and JavaScript is responsible for game logic and user interface.

JavaScript is widely used in websites, mobile applications, desktop applications and server-side programming. 1) In website development, JavaScript operates DOM together with HTML and CSS to achieve dynamic effects and supports frameworks such as jQuery and React. 2) Through ReactNative and Ionic, JavaScript is used to develop cross-platform mobile applications. 3) The Electron framework enables JavaScript to build desktop applications. 4) Node.js allows JavaScript to run on the server side and supports high concurrent requests.

Python is more suitable for data science and automation, while JavaScript is more suitable for front-end and full-stack development. 1. Python performs well in data science and machine learning, using libraries such as NumPy and Pandas for data processing and modeling. 2. Python is concise and efficient in automation and scripting. 3. JavaScript is indispensable in front-end development and is used to build dynamic web pages and single-page applications. 4. JavaScript plays a role in back-end development through Node.js and supports full-stack development.

C and C play a vital role in the JavaScript engine, mainly used to implement interpreters and JIT compilers. 1) C is used to parse JavaScript source code and generate an abstract syntax tree. 2) C is responsible for generating and executing bytecode. 3) C implements the JIT compiler, optimizes and compiles hot-spot code at runtime, and significantly improves the execution efficiency of JavaScript.

JavaScript's application in the real world includes front-end and back-end development. 1) Display front-end applications by building a TODO list application, involving DOM operations and event processing. 2) Build RESTfulAPI through Node.js and Express to demonstrate back-end applications.

The main uses of JavaScript in web development include client interaction, form verification and asynchronous communication. 1) Dynamic content update and user interaction through DOM operations; 2) Client verification is carried out before the user submits data to improve the user experience; 3) Refreshless communication with the server is achieved through AJAX technology.

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.
