Dreamweaver customized web page transition function: First open the page with Dreamweaver , and then click InsertHeadMeta (Insert/File Header Tag/Meta) in the menu.
Select the HTTP-equivalent option in the drop-down list of the Attribute option in the dialog box, and type Page-Enter in Value: There is a webpage transition effect when entering the webpage. Type Revealtrans(Duration=6,Transition=2) in Content:, Duration=6 means the duration of the webpage transition effect is 6 seconds, Transition means the transition effect mode, and a value of 2 means circular shrinkage.
Click OK after inputting to save. In this way, when we click a hyperlink to enter this page, we can see the effect. There are more than twenty kinds of effects for you to choose from. Just change the value of Transition to the code name of the corresponding effect. The specific effects and settings are as shown in the table below:
Effect Content Transitionv Box-shaped Contract RevealTrans 0 Except RevealTrans 6
Erase right RevealTrans 7 Vertical blinds RevealTrans 8
Horizontal blinds RevealTrans 9
Horizontal checkerboard RevealTrans 10
Vertical checkerboard RevealTrans 11
Dissolve RevealTrans 12
Shrink left and right towards the middle RevealTrans 13
Expand the middle left and right RevealTrans 14
Shrink up and down towards the middle RevealTrans 15
Expand up and down in the middle RevealTrans 16
Expand stepwise to the left and down RevealTrans 17
Ladder-like expansion to the upper left RevealTrans 18
Ladder-like expansion to the lower right RevealTrans 19
Ladder-like expansion to the upper right RevealTrans 20
Random horizontal line RevealTrans 21
Random vertical line RevealTrans 22
Random RevealTrans 23

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

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.
