In recent projects, vue has been used to replace the cumbersome jquery to handle dom data updates. I personally like it very much, so I went to the official website to practice it a little.
The following is the practice of form control, the code is respectful, create a new html file directly, paste and copy to see the effect
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>PlayAround2 Have Fun</title> <script src="https://cdn.jsdelivr.net/vue/1.0.26/vue.min.js"></script> <style> h2{ text-decoration:underline; } .red{ color: red; } .green{ color: green; } </style> </head> <body> <div id="app"> <h2 id="checkBox">checkBox</h2> <input type="checkbox" v-model="checked"> <label>{{checked}}</label> <h2 id="multi-nbsp-checkbox">multi checkbox</h2> <input type="checkbox" id="Kobe" value="Kobe" v-model="names"> <label for="Kobe">Kobe</label> <input type="checkbox" id="Curry" value="Curry" v-model="names"> <label for="Curry">Curry</label> <input type="checkbox" id="Aaron" value="Aaron" v-model="names"> <label for="Aaron">Aaron</label> <br> <span>Checked names: {{names | json}}</span> <h2 id="Radio">Radio</h2> <input type="radio" id="one" value="one" v-model="picked"> <label for="one">one</label> <br> <input type="radio" id="two" value="two" v-model="picked"> <label for="two">two</label> <br> <span>Picked: {{picked}}</span> <h2 id="Select">Select</h2> <select v-model="selected"> <option selected>Kobe</option> <option>Curry</option> <option>Aaron</option> </select> <span>Selected: {{selected}}</span> <h2 id="Multi-nbsp-Select">Multi Select</h2> <select multiple v-model="multiSelected"> <option>Kobe</option> <option>Curry</option> <option>Aaron</option> </select> <span>Selected: {{multiSelected}}</span> <h2 id="Select-nbsp-with-nbsp-for">Select with for</h2> <select v-model="selectedPlayer"> <option v-for="option in options" :value="option.value">{{option.text}}</option> </select> <span>Selected: {{selectedPlayer}}</span> <h2 id="Lazy-改变更新的事件从input-change">Lazy-改变更新的事件从input->change</h2> <input v-model="msg" lazy> <span>Msg:{{msg}}</span> <h2 id="Number-没啥吊用-仅此而已吗">Number(没啥吊用。。。.2->0.2,仅此而已吗?)</h2> <input v-model="age" number> <span>age:{{age}}</span> <h2 id="debounce-延迟更新view">debounce-延迟更新view</h2> <p>Edit me<input v-model="delayMsg" debounce="500"></p> <span>delayMsg:{{delayMsg}}</span> </div> <script> var vm = new Vue({ el:"#app", data:{ checked:false, names:[], picked:"", selected:"", multiSelected:"", options:[ {text:"Kobe",value:"Bryant"}, {text:"Stephen",value:"Curry"}, {text:"Aaron",value:"Kong"} ], selectedPlayer:"", msg:"", age:"", delayMsg:"" }, methods:{ } }) </script> </body> </html>
Several advantages of using vue:
1. Just pay attention to the data of the model layer Processing, there is no need to deal with complex view layer updates, vue will automatically update the view layer when the model changes;
2. Vue provides a series of small tools to help developers deal with problems in data binding, such as computed can provide The expansion of calculations also supports filters, sorting, etc.;
3. The code is concise and layered clearly. Data binding is done in html, while js only needs to process data and background interaction;
4. Provide custom component functions to further standardize the front-end architecture. It is currently not in use and will be studied in the future.
The above is my current experience of using Vue. I haven’t found any shortcomings yet, and it may not be too in-depth. Overall, the experience is very good!

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.

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.

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
