Ajax framework

An Ajax framework is a framework that helps to develop web applications that use Ajax, a collection of technologies used to build dynamic web pages on the client side. Data is read from the server or sent to the server by JavaScript requests. However, some processing at the server side may be required to handle requests, such as finding and storing the data. This is accomplished more easily with the use of a framework dedicated to process Ajax requests. The goal of the framework is to provide the Ajax engine described below and associated server and client-side functions.

In the article that coined the "Ajax" term, J.J. Garrett describes the technology as "an intermediary...between the user and the server." This Ajax engine is intended to suppress the delays perceived by the user when a page attempts to access the server. A framework eases the work of the Ajax programmer at two levels: on the client side, it offers JavaScript functions to send requests to the server. On the server side, it processes the requests, searches for the data, and transmits them to the browser. Some frameworks are very elaborate and provide a complete library to build web applications.

These frameworks require HTML, CSS and Ajax expertise: a developer is expected to author pages directly in HTML, and framework APIs deal directly with HTML elements. Cross-browser APIs are provided for a variety of purposes, commonly including communications, DOM manipulation, event handling, and sizing/moving/animating HTML elements.

These frameworks are generally smaller. They are commonly used for a web site such as a shopping experience, but not for a web application such as web-based email, at least not without further frameworks layered on top.

These frameworks are based on compiler technology, where, instead of writing direct Ajax and Javascript, a high-level language is used instead, along with a compiler that turns the high-level language into Javascript. Indirect frameworks therefore require knowledge of the high-level language, CSS and HTML, and do not necessarily require a great deal of Ajax or Javascript expertise. The Indirect frameworks are typically accompanied by convenient libraries, modules and classes (written in the high-level language) that take care of communications, DOM manipulation including HTML element manipulation, and event handling.

Interestingly, Python and Ruby are a good match for compilation to Javascript, and a far better match than Java, because Java (and Java Virtual Machines) lack some of the run-time dynamic capabilities of Javascript, Python and Ruby. Fortunately for Java (and for GWT), it's Java that is less dynamically capable than Javascript. The "class" capability of these high-level languages can be emulated using Javascript "prototype".

These frameworks offer pre-built components, such as tabbed panes, which automatically create and manage their own HTML. Components are generally created via JavaScript or XML tags, or by adding special attributes to normal HTML elements. These frameworks are generally larger, and intended for web applications rather than web sites.

Some component frameworks require the developer to have extensive HTML/CSS/Ajax experience and to do cross-browser testing. For example, grids, tabs, and buttons may be provided, but user input forms are expected to be authored directly in HTML/CSS and manipulated via Ajax techniques. Other frameworks provide a complete component suite such that only general XML and/or JavaScript abilities are required.

Several frameworks offer a server-side component-based development model with some degree of Ajax support.

Components are created and manipulated on the server using a server-side programming language. Pages are then rendered by a combination of server-side and client-side HTML generation and manipulation. User actions are communicated to the server via Ajax techniques, server-side code manipulates a server-side component model, and changes to the server component model are reflected on the client automatically.

These frameworks offer familiarity and efficiency for server-side developers at the possible expense of power and performance. Ajax frameworks that handle presentation completely within the browser may offer greater responsiveness if they handle more user interactions without server involvement. In a server-driven model, some UI interactions can react slowly, for example when an input field is dynamically enabled based on server-requests. Furthermore, server-dependent Ajax frameworks can not offer offline support. The approach is still popular for situations where the benefits of a full Ajax architecture can't be captured or where server interaction is needed anyway.

Extending such a framework may require the developer to understand which parts of the presentation are handled on the client vs on the server, and to code in JavaScript/Ajax as well as server-side code (an issue which can be overcome through the use of an Indirect Ajax framework, by choosing an Indirect Ajax framework with a compiler that accepts the same language as the server-side code).

ASP.NET AJAX

ASP.NET AJAX, formerly code-named Atlas, is a set of extensions to ASP.NET developed by Microsoft for implementing Ajax functionality. Ajax, shorthand for Asynchronous JavaScript and XML, is a web development technique for creating interactive web applications.

Including both client-side and server-side components, ASP.NET AJAX allows the developer to create web applications in ASP.NET 2.0 (and to a limited extent in other environments) which can update data on the web page without a complete reload of the page. The key technology which enables this functionality is the XMLHttpRequest object, along with Javascript and DHTML.

ASP.NET AJAX was released as a standalone extension to ASP.NET in January 2007 after a lengthy period of beta-testing. It was subsequently included with version 3.5 of the .NET Framework, which was released alongside Visual Studio 2008 in November 2007.

After an Ajax request, the HTML within some portions of the page (for ASP.NET Ajax this is the "update panel") is completely re-rendered with new HTML so it's impossible to keep client side state across Ajax Server Side event handlers. This is reflected in the fact that the Auto Completer in the ASP.NET Ajax Control library (which is an extension to ASP.NET Ajax) has to use WebServices to retrieve data instead of the far more intuitive way which would have been to use a server side event handler embedded as a method into the page the control resides within.

On 11 September 2006, Scott Guthrie, General Manager in charge of the .NET platform at that time, announced that ATLAS would be renamed and launched as three products towards the end of the year. The new products were to be called the Microsoft AJAX Library, containing the front end JavaScript library, the ASP.NET 2.0 AJAX Extensions, containing the server-side .NET code, and ASP.NET AJAX Control Toolkit, containing shared source controls that could be used to "get the most value from the ASP.NET AJAX Extensions".

A major change since its inception includes the change of the root namespace from "Microsoft.Web" to "System.Web".

The production version was released on 23 January 2007.

The Microsoft AJAX Library is a standalone collection of the standards-based JavaScript classes included in ASP.NET AJAX. It is supported by most popular browsers and can be used to build client-centric web applications that integrate with any backend data provider.

ASP.NET AJAX supports multiple modern web browsers such as Internet Explorer, Firefox, Opera and Safari. Mobile devices such as Windows Mobile are currently not supported.

Ajax Orlando Prospects were an American soccer team, founded in 2002. The team was a member of the United Soccer Leagues Premier Development League (PDL), the fourth tier of the American Soccer Pyramid, until 2006, when the team left the league and the franchise was terminated.

The Prospects played their home games at Warden Stadium on the grounds of The First Academy, a Christian college preparatory school in Orlando, Florida. The team's colors were white, red and black.

The team was part of the Ajax America organisation, an exclusive affiliate of the renowned Dutch football club AFC Ajax’s North American marketing and player development program.
