Ajax programming WikipediaAJAX redirects here. For other uses, see Ajax. Ajax also AJAX short for asynchronous Java. Script and XML1 is a set of Web development techniques using many Web technologies on the client side to create asynchronous. Web applications. With Ajax, Web applications can send data to and retrieve from a server asynchronously in the background without interfering with the display and behavior of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows for Web pages, and by extension Web applications, to change content dynamically without the need to reload the entire page. In practice, modern implementations commonly substitute JSON for XML due to the advantages of being native to Java.

Ajax is not a single technology, but rather a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with Java. Script to dynamically display and allow the user to interact with the information presented. Java. Script and the XMLHttp. Request object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads. HistoryeditIn the early to mid 1. Web sites were based on complete HTML pages. Each user action required that a complete new page be loaded from the server. This process was inefficient, as reflected by the user experience all page content disappeared, then the new page appeared. Each time the browser reloaded a page because of a partial change, all of the content had to be re sent, even though only some of the information had changed. This placed additional load on the server and made bandwidth a limiting factor on performance. In 1. 99. 6, the iframe tag was introduced by Internet Explorer like the object element it can load or fetch content asynchronously. In 1. 99. 8, the Microsoft Outlook Web App team developed the concept behind the XMLHttp. Request scripting object. It appeared as XMLHTTP in the second version of the MSXML library,45 which shipped with Internet Explorer 5. March 1. 99. 9. 6The functionality of the XMLHTTP Active. X control in IE 5 was later implemented by Mozilla, Safari, Opera and other browsers as the XMLHttp. Request Java. Script object. Microsoft adopted the native XMLHttp. Request model as of Internet Explorer 7. The Active. X version is still supported in Internet Explorer, but not in Microsoft Edge. The utility of these background HTTP requests and asynchronous Web technologies remained fairly obscure until it started appearing in large scale online applications such as Outlook Web App 2.

The term Ajax was publicly used on 1. February 2. 00. 5 by Jesse James Garrett in an article titled Ajax A New Approach to Web Applications, based on techniques used on Google pages. On 5 April 2.

Ajax Jquery Php Tutorial Pdf' title='Ajax Jquery Php Tutorial Pdf' />The conventional model for a Web Application versus an application using Ajax. The term Ajax has come to represent a broad group of Web technologies that can be used to implement a Web application that communicates with a server in the background, without interfering with the current state of the page. In the article that coined the term Ajax,12 Jesse James Garrett explained that the following technologies are incorporated Since then, however, there have been a number of developments in the technologies used in an Ajax application, and in the definition of the term Ajax itself. XML is no longer required for data interchange and, therefore, XSLT is no longer required for the manipulation of data. Java. Script Object Notation JSON is often used as an alternative format for data interchange,1. HTML or plain text can also be used. A variety of popular Java. Script libraries, including JQuery, include abstractions to assist in executing Ajax requests. Asynchronous HTML and HTTP AHAH involves using XMLHTTPRequest to retrieve XHTML fragments, which are then inserted directly into the Web page. Ajax Jquery Php Tutorial Pdf' title='Ajax Jquery Php Tutorial Pdf' />DrawbackseditAny user whose browser does not support Java. Script or XMLHttp. Request, or has this functionality disabled, will not be able to properly use pages that depend on Ajax. Simple devices such as smartphones and PDAs may not support the required technologies. The only way to let the user carry out functionality is to fall back to non Java. Script methods. This can be achieved by making sure links and forms can be resolved properly and not relying solely on Ajax. Similarly, some Web applications that use Ajax are built in a way that cannot be read by screen reading technologies, such as JAWS. The WAI ARIA standards provide a way to provide hints in such a case. Screen readers that are able to use Ajax may still not be able to properly read the dynamically generated content. The same origin policy prevents some Ajax techniques from being used across domains,1. W3. C has a draft of the XMLHttp. Request object that would enable this functionality. Methods exist to sidestep this security feature by using a special Cross Domain Communications channel embedded as an iframe within a page,2. JSONP. The asynchronous callback style of programming required can lead to complex code that is hard to maintain, to debug2. Because of the asynchronous nature of Ajax, each chunk of data that is sent or received by the client occurs in a connection established specifically for that event. This creates a requirement that for every action, the client must poll the server, instead of listening, which incurs significant overhead. This overhead leads to several times higher latency with Ajax than what can be achieved with a technology such as websockets. In pre HTML5 browsers, pages dynamically created using successive Ajax requests did not automatically register themselves with the browsers history engine, so clicking the browsers back button may not have returned the browser to an earlier state of the Ajax enabled page, but may have instead returned to the last full page visited before it. Such behavior  navigating between pages instead of navigating between page states  may be desirable, but if fine grained tracking of page state is required, then a pre HTML5 workaround was to use invisible iframes to trigger changes in the browsers history. A workaround implemented by Ajax techniques is to change the URL fragment identifier the part of a URL after the when an Ajax enabled page is accessed and monitor it for changes. HTML5 provides an extensive API standard for working with the browsers history engine. Dynamic Web page updates also make it difficult to bookmark and return to a particular state of the application. Solutions to this problem exist, many of which again use the URL fragment identifier. On the other hand, as AJAX intensive pages tend to function as applications rather than content, bookmarking interim states rarely makes sense. Query AJAX para realizar consultas con PHP y My.
