Implementation steps of JS operating window object
Let me introduce to you the property methods of JS operating window object and the implementation steps of JS operating window object. Let’s give you a small case to help you understand. Let’s take a look.
-------------------------------------------------- --------------------------
Note: The name attribute of the element on the page and the name referenced by JavaScript must be consistent including upper and lower case
Otherwise it will Prompt you with an error message "The referenced element is empty or not an object"
-------------------------- -----------------------------------------------
Object properties
window.opener opener属性与打开该窗口的父窗口相联系,当访问子窗口中operer属性时 ,返回的是父窗口。通过该属性,可以使用父窗口对象中的方法和属性。 window //窗口自身 window.self //引用本窗口window=window.self window.closed //表示窗口是否已经关闭 window.name //为窗口命名 window.defaultStatus //设定窗口状态栏信息 window.location //URL地址,设置这个属性可以打开新的页面
------------------------------------------------ --------------------------
Object Method
window.alert("text") //提示信息对话框 window.confirm("text") //确认对话框 window.prompt("text") //要求键盘输入对话框 window.setIntervel("action",time) //每隔指定的时间(毫秒)就执行一次操作 window.clearInterval() //清除时间设置作用就是终止循环 window.setTimeout(action,time) //隔了指定的时间(毫秒)执行一次操作 window.open() //打开新的窗口 window.close() //关闭脚本所在窗口
-------- -------------------------------------------------- ----------
Member Object
window.event window.document //见document对象详解 window.history window.screen window.navigator window.external
------------------------ ----------------------------------------
window. history object
window.history.length //浏览过的页面数 history.back() //后退 history.forward() //前进 history.go(i) //到历史清单的第i位 //i>0前进,i<0后退
-------------------------------- -------------------------------------
window.screen object
window.screen.width //屏幕宽度 window.screen.height //屏幕高度 window.screen.colorDepth //屏幕色深 window.screen.availWidth //可用宽度 window.screen.availHeight //可用高度(除去任务栏的高度)
---------------------------------------- --------------------------
window.external object
window.external.AddFavorite("地址","标题" ) //把网站添加到收藏夹
- -------------------------------------------------- ------------------
window.navigator object
window.navigator.appCodeName //浏览器代码名 window.navigator.appName //浏览器程序名 window.navigator.appMinorVersion //浏览器补丁版本 window.navigator.cpuClass //cpu类型 x86 window.navigator.platform //操作系统类型 win32 window.navigator.plugins window.navigator.opsProfile window.navigator.userProfile window.navigator.systemLanguage //客户系统语言 zh-cn简体中文 window.navigator.userLanguage //用户语言,同上 window.navigator.appVersion //浏览器版本(包括系统版本) window.navigator.userAgent window.navigator.onLine //用户否在线 window.navigator.cookieEnabled //浏览器是否支持cookie window.navigator.mimeTypes
--------- -------------------------------------------------- ----------
<!--window对象方法示例脚本--> <script language="javascript"> window.alert("您好!")</script> <script language="javascript"> var action action=window.confirm("请选择操作...") if(action) document.write("您选择了继续操作") else document.write("您选择了取消操作")</script> <script language="javascript"> var info info=window.prompt("请输入一些必要的信息") document.write (info)</script> <script language="javascript"> var i;i=0; function action(){ i++; window.alert(i) //监视循环情况 if(i>=10) window.clearInterval(stop) //终止循环 } stop=window.setInterval("action()",1000)//1000毫秒=1秒</script> <script language="javascript"> var i;i=0; function action(){ i++; window.alert(i) //监视循环情况 } window.setTimeout("action()",1000) //相同的代码setTimeout只执行一次</script></html>

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.

JavaScript is the core language of modern web development and is widely used for its diversity and flexibility. 1) Front-end development: build dynamic web pages and single-page applications through DOM operations and modern frameworks (such as React, Vue.js, Angular). 2) Server-side development: Node.js uses a non-blocking I/O model to handle high concurrency and real-time applications. 3) Mobile and desktop application development: cross-platform development is realized through ReactNative and Electron to improve development efficiency.

The latest trends in JavaScript include the rise of TypeScript, the popularity of modern frameworks and libraries, and the application of WebAssembly. Future prospects cover more powerful type systems, the development of server-side JavaScript, the expansion of artificial intelligence and machine learning, and the potential of IoT and edge computing.
