Other encodings are optimized for this encoding, such as UTF-8,GBK.UTF-8: Compression and refinement of Unicode (numbers, letters and ASCII codes using 8-bit encoding to store), Python3 default encoding used, European characters: 2 bytes, 16-bit storage; Chinese characters: 3 bytes, 24 bit storageSummary: Python3 default encoding is UTF-8, encoding conversion principle: first converted to

How Ajax works and its pros and cons 1. What is Ajax? Ajax is all called "Asynchronous JavaScript and XML" (Asynchronous JavaScript and XML) and is a web development technique for creating interactive Web applications. It uses: Xhtml+css to standardize rendering, data exchange and related operations using XML and XSLT, asynchronous communication with the Web server using the XMLHttpRequest object, and using JavaScript to manipulate the Document object

Simple: A cookie is a lightweight, text-based structure that includes simple key-value pairs3. Data persistence: Because it is saved to the client4. No server resources: Because the local client is storedDisadvantages:1. Do not store sensitive information in cookies, such as usernames, passwords, credit card numbers, etc.2. Encrypt the inform

to send an asynchronous request to the server via the XMLHttpRequest object, get the data from the server, and then use JavaScript to manipulate the DOM and update the page. One of the most critical steps is getting the request data from the server. To understand this process and principle, we must have some knowledge of xmlhttprequest.XMLHttpRequest is the core mechanism of Ajax, which was first introduced in IE5 and is a technique that supports asynchronous requests. Simply put, JavaScript ca

standards of the Web.5.AJAX points of attention and applicable and non-applicable scenarios(1). Attention PointWhen Ajax is developed, network latency-that is, the interval between a user sending a request to a server to make a response-requires careful consideration. Not giving users a clear response, without proper pre-reading data, or improper handling of XMLHttpRequest, will make users feel delayed, which users do not want to see, but they do not understand. A common solution is to use a vi

1. Make complex projects easier to maintain by dividing the project into model View and controller.2. The view state and server form controls are not used, which makes it easier to control the behavior of the application3. The application uses a controller to control the request and can provide a rich URL rewrite.4. Better support for unit testing5. Better performance in team development modethe lack of MVC:(1) Increase the complexity of the system structure and implementation. For a simple inte
