In what year was ajax released?
ajax was released on February 18, 2005. AJAX stands for "Asynchronous JavaScript and XML" (asynchronous JavaScript and XML technology), which refers to a set of browser-side web development technologies that combine multiple technologies. The concept of Ajax was proposed by Jesse James Jarrett.
Jesse James Garrett (English: Jesse James Garrett) is a designer in the field of user experience design, the founder of the web experience design company Adaptive Path, and a When using a browser to browse web pages; the name of the concept of asynchronous update technology "AJAX" that reduces the need to consume resources sent by the server when updating content on the page.
History of ajax development:
In the 1990s, almost all websites were implemented by HTML pages, and the server needed to be reloaded to process every user request. Web page. This processing method is not efficient. The user experience is that all pages will disappear and then be reloaded. Even if only a part of the page elements change, the entire page must be reloaded. Not only the changed parts must be refreshed, but also the parts that have not changed. This will increase the load on the server.
This can be solved with asynchronous loading. In 1995, the first version of the JAVA language was released, and the Java applets (JAVA applets) released subsequently implemented asynchronous loading for the first time. The browser exchanges data with the server by running Java applets embedded in the web page without having to refresh the web page. In 1996, Internet Explorer added the iframe element to HTML to support partial refresh of web pages.
Around 1998, the Outlook Web Access team wrote the first component that allowed client-side scripts to send HTTP requests (XMLHTTP). This component originally belonged to Microsoft Exchange Server and quickly became part of Internet Explorer 4.0[2]. Some observers believe that Outlook Web Access was the first successful business application to use Ajax technology, and it became the lead for many products, including Oddpost's webmail product. However, in early 2005, many events made Ajax more widely accepted. Google uses asynchronous communication in its famous interactive applications, such as Google Discussion Groups, Google Maps, Google Search Suggestions, Gmail, etc. The term Ajax was coined by the article "Ajax: A New Approach to Web Applications", whose rapid spread increased people's awareness of the use of this technology. In addition, support for Mozilla/Gecko makes the technology mature and easier to use.
Application
Use XHTML CSS to express information;
Use JavaScript to operate DOM (Document Object Model) to perform dynamic effects;
Use XML and XSLT to operate data
Use XMLHttpRequest or the new Fetch API to exchange data asynchronously with the web server;
Note: AJAX is related to RIA technologies such as Flash, Silverlight and Java Applet differentiated.

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

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.

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

Using Ajax to obtain variables from PHP methods is a common scenario in web development. Through Ajax, the page can be dynamically obtained without refreshing the data. In this article, we will introduce how to use Ajax to get variables from PHP methods, and provide specific code examples. First, we need to write a PHP file to handle the Ajax request and return the required variables. Here is sample code for a simple PHP file getData.php:

Ajax (Asynchronous JavaScript and XML) allows adding dynamic content without reloading the page. Using PHP and Ajax, you can dynamically load a product list: HTML creates a page with a container element, and the Ajax request adds the data to that element after loading it. JavaScript uses Ajax to send a request to the server through XMLHttpRequest to obtain product data in JSON format from the server. PHP uses MySQL to query product data from the database and encode it into JSON format. JavaScript parses the JSON data and displays it in the page container. Clicking the button triggers an Ajax request to load the product list.

In order to improve Ajax security, there are several methods: CSRF protection: generate a token and send it to the client, add it to the server side in the request for verification. XSS protection: Use htmlspecialchars() to filter input to prevent malicious script injection. Content-Security-Policy header: Restrict the loading of malicious resources and specify the sources from which scripts and style sheets are allowed to be loaded. Validate server-side input: Validate input received from Ajax requests to prevent attackers from exploiting input vulnerabilities. Use secure Ajax libraries: Take advantage of automatic CSRF protection modules provided by libraries such as jQuery.

Ajax is not a specific version, but a technology that uses a collection of technologies to asynchronously load and update web page content. Ajax does not have a specific version number, but there are some variations or extensions of ajax: 1. jQuery AJAX; 2. Axios; 3. Fetch API; 4. JSONP; 5. XMLHttpRequest Level 2; 6. WebSockets; 7. Server-Sent Events; 8, GraphQL, etc.
