AJAX simple asynchronous communication example analysis

In the previous article (link), Xiao Zaojun introduced the development history of broadband technology from ISDN, xDSL to 10GPON. Today, let’s talk about the upcoming new generation of optical fiber broadband technology-50GPON. █F5G and F5G-A Before introducing 50GPON, let’s talk about F5G and F5G-A. In February 2020, ETSI (European Telecommunications Standards Institute) promoted a fixed communication network technology system based on 10GPON+FTTR, Wi-Fi6, 200G optical transmission/aggregation, OXC and other technologies, and named it F5G. That is, the fifth generation fixed network communication technology (The5thgenerationFixednetworks). F5G is a fixed network

Build an autocomplete suggestion engine using PHP and Ajax: Server-side script: handles Ajax requests and returns suggestions (autocomplete.php). Client script: Send Ajax request and display suggestions (autocomplete.js). Practical case: Include script in HTML page and specify search-input element identifier.

Title: Methods and code examples to resolve 403 errors in jQuery AJAX requests. The 403 error refers to a request that the server prohibits access to a resource. This error usually occurs because the request lacks permissions or is rejected by the server. When making jQueryAJAX requests, you sometimes encounter this situation. This article will introduce how to solve this problem and provide code examples. Solution: Check permissions: First ensure that the requested URL address is correct and verify that you have sufficient permissions to access the resource.

jQuery is a popular JavaScript library used to simplify client-side development. AJAX is a technology that sends asynchronous requests and interacts with the server without reloading the entire web page. However, when using jQuery to make AJAX requests, you sometimes encounter 403 errors. 403 errors are usually server-denied access errors, possibly due to security policy or permission issues. In this article, we will discuss how to resolve jQueryAJAX request encountering 403 error

How to solve the problem of jQueryAJAX error 403? When developing web applications, jQuery is often used to send asynchronous requests. However, sometimes you may encounter error code 403 when using jQueryAJAX, indicating that access is forbidden by the server. This is usually caused by server-side security settings, but there are ways to work around it. This article will introduce how to solve the problem of jQueryAJAX error 403 and provide specific code examples. 1. to make

In today's digital age, broadband has become a necessity for each of us and every family. Without it, we would be restless and restless. So, do you know the technical principles behind broadband? From the earliest 56k "cat" dial-up to the current Gigabit cities and Gigabit homes, what kind of changes has our broadband technology experienced? In today’s article, let’s take a closer look at the “Broadband Story”. Have you seen this interface between █xDSL and ISDN? I believe that many friends born in the 70s and 80s must have seen it and are very familiar with it. That's right, this was the interface for "dial-up" when we first came into contact with the Internet. That was more than 20 years ago, when Xiao Zaojun was still in college. In order to surf the Internet, I

PHP is a commonly used development language that can be used to develop various web applications. In addition to common HTTP requests and responses, PHP also supports network communication through Sockets to achieve more flexible and efficient data interaction. This article will introduce the methods and techniques of how to implement Socket communication in PHP, and attach specific code examples. What is Socket Communication Socket is a method of communication in a network that can transfer data between different computers. by S

Original title: "How does a wireless mouse become wireless?" 》Wireless mice have gradually become a standard feature of today’s office computers. From now on, we no longer have to drag long cords around. But, how does a wireless mouse work? Today we will learn about the development history of the No.1 wireless mouse. Did you know that the wireless mouse is now 40 years old? In 1984, Logitech developed the world's first wireless mouse, but this wireless mouse used infrared as a The signal carrier is said to look like the picture below, but later failed due to performance reasons. It was not until ten years later in 1994 that Logitech finally successfully developed a wireless mouse that works at 27MHz. This 27MHz frequency also became the wireless mouse for a long time.
