The operating environment of this tutorial: windows7 system, jquery1.10.0 version, Dell G3 computer.
How jquery hides tr in table
1. Create a new html file and name it test.html to explain how jquery determines Whether the element is visible. In the test.html file, use the table, tr, and td tags to create a table with six rows and two columns. To facilitate viewing, set a 1px border for the table. In the test.html file, in the table table, set the class attribute of part of tr to aa, and set the id of the last row to bb.
In the test.html file, use the button tag to create two buttons, namely "Hide tr" and "Show tr". The code is as follows:
2. In the test.html file, bind onclick events to the two button buttons respectively. When the buttons are clicked, the "hiddentr()" function and the "displaytr()" function are executed respectively.
In the js tag, create the hiddentr() function and the displaytr() function. In the hiddentr() function, obtain the tr row object with class aa. Use the hide() method to hide tr. In displaytr( ) function, obtain the tr row object with id bb, and use the show() method to display tr.
Open the test.html file in the browser and click on the buttons to see the effect.
After clicking to hide tr
Create a test.html file. Within the file, use the table, tr, and td tags to create a table with six rows and two columns. Create two button buttons at the same time to trigger the execution of js functions. In the js tag, create the hiddentr() function and the displaytr() function. In the hiddentr() function, obtain the tr row object with class aa. Use the hide() method to hide tr. In the displaytr() function, obtain the id. For the tr row object of bb, use the show() method to display tr.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

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.
