源码说明
jquery 源码给我很大帮助,也用到一个叫 布鲁斯 · 李 的同学的源码,当然更多资源来源于网络。
功能说明
// jelle(elem) 对象 elem传递对象ID 或者 dom对象 如果是窗口 传递 window 对象
//.offset() 返回当前对象相对浏览器的绝对位置 ,返回值 = {top:a,left:b};
//.inner() 返回当前对象可见区域 宽度与高度 ,返回值 = {wisth:a,left:b};
//.scroll() 返回当前对象被卷区top 和 left。 ,返回值 = {top:a,left:b};
//.offparent() 返回当前对象距离父节点的位置 top left。 ,返回值 = {top:a,left:b};
//.client() 返回当前对象的可用高度和宽度 ,返回值 = {width:a,height:b};
//.screen() 返回当前屏幕的可用高度和宽度 ,返回值 = {width:a,height:b};
//.mouse(event) 返回当前鼠标的x,y坐标,elem不为空返回相对elem的坐标 ,返回值 = {x:a,y:b};
例子
//例子: 返回一个ID 为 test 的div 的可见区域宽度 //jelle('test').inner().width //这里可以紧接后面直接下 width

OK 这里是一个测试的地方。他包含3个DIV嵌套

JavaScript core data types are consistent in browsers and Node.js, but are handled differently from the extra types. 1) The global object is window in the browser and global in Node.js. 2) Node.js' unique Buffer object, used to process binary data. 3) There are also differences in performance and time processing, and the code needs to be adjusted according to the environment.

The main difference between Python and JavaScript is the type system and application scenarios. 1. Python uses dynamic types, suitable for scientific computing and data analysis. 2. JavaScript adopts weak types and is widely used in front-end and full-stack development. The two have their own advantages in asynchronous programming and performance optimization, and should be decided according to project requirements when choosing.

Whether to choose Python or JavaScript depends on the project type: 1) Choose Python for data science and automation tasks; 2) Choose JavaScript for front-end and full-stack development. Python is favored for its powerful library in data processing and automation, while JavaScript is indispensable for its advantages in web interaction and full-stack development.

Python and JavaScript each have their own advantages, and the choice depends on project needs and personal preferences. 1. Python is easy to learn, with concise syntax, suitable for data science and back-end development, but has a slow execution speed. 2. JavaScript is everywhere in front-end development and has strong asynchronous programming capabilities. Node.js makes it suitable for full-stack development, but the syntax may be complex and error-prone.

JavaScript can be used for front-end and back-end development. The front-end enhances the user experience through DOM operations, and the back-end handles server tasks through Node.js. 1. Front-end example: Change the content of the web page text. 2. Backend example: Create a Node.js server.

Choosing Python or JavaScript should be based on career development, learning curve and ecosystem: 1) Career development: Python is suitable for data science and back-end development, while JavaScript is suitable for front-end and full-stack development. 2) Learning curve: Python syntax is concise and suitable for beginners; JavaScript syntax is flexible. 3) Ecosystem: Python has rich scientific computing libraries, and JavaScript has a powerful front-end framework.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
