How to use jquery to implement select all and unselect all functions
How to use jquery to implement the select all and unselect functions: first introduce the jquery library and set the loading function of jquery; then obtain the elements of the all-select box based on the id, and bind the click to the all-select box Event; finally get the multi-select box whose class attribute value is checkOne.
The operating environment of this tutorial: windows7 system, jquery3.2.1 version, Dell G3 computer. This method is suitable for all brands of computers.

How to use jquery to implement the select all and unselect functions:
1. Create an html, and then add the code as shown below in the body tag, mainly to include multi-select boxes in a table.
#2. Then the first thing is to introduce the jquery library. Pay attention to the way of jquery library: <script src="js/jquery-1.8.3.js"></script>
cannot be written as
<script src="js/jquery-1.8.3.js"></script>
This way. Otherwise it is invalid! You can try the difference between the two.
html5 does not need to add type="text/javascript"
3, and then there is a jquery loading function. The loading function is jquery's standard configuration. The following method is relatively abbreviated.
#4. Next, get the elements of the all-select box based on the id, and then bind the click event to the all-select box.
5. Complete in the click event method: Get the multi-select box whose class attribute value is checkOne; then use the prop (property, value) method to set the checked attribute Set it to be the same as checked in the Select All/Uncheck All box.
#6. The above steps have completed the use of jquery to implement the functions of selecting all and not selecting all. We run this html through the browser to see the effect as follows.

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.
