Enhance existing pages using powerful AJAX controls with support for all modern browsers.Enjoy the benefits of a free framework with technical support provided by Microsoft.NET AJAX in your own applications!NET AJAX: A demonstration of ASP.NET AJAX Support in Visual Studio 2008:
You will get a quick overview of the inclusion of ASP.NET AJAX into Visual Studio 2008 (Orcas) and .This will be demonstrated by using Visual Studio 2008 and the building of web site application.NET AJAX Tool Kit
ASP.Questions or problems with www.Skip to main content
Visit Mozilla.Getting StartedAn introduction to AJAX.When these technologies are combined in the AJAX model, web applications are able to make quick, incremental updates to the user interface without reloading the entire browser page.Alternate Ajax Techniques
Most articles on Ajax have focused on using XMLHttp as the means to achieving such communication, but Ajax techniques are not limited to just XMLHttp.Ajax: A New Approach to Web Applications
Jesse James Garrett, of adaptive path, wrote this article in February 2005, introducing AJAX and its related concepts.Simpler Ajax Path
"As it turns out, it's pretty easy to take advantage of the XMLHttpRequest object to make a web app act more like a desktop app while still using traditional tools like web forms for collecting user input."Fixing the Back Button and Enabling Bookmarking for AJAX Apps
Mike Stenhouse has penned this article, detailing some methods you can use to fix back button and bookmarking issues when developing AJAX applications.Ajax Mistakes
Alex Bosworth has written this article outlining some of the mistakes AJAX application developers can make.Other resources
Other AJAX resources you may find useful.This page was last modified 23:23, 24 May 2008.This page has been accessed 710,021 times.With Ajax, user interfaces from within the browser can use web services as their data source to store and retrieve information.Dealing with Long Running Processes in ASP.In the second part of this article the AJAX enabled grid is made editable.GWT has integrated into its framework.Use ICallbackEventHandler to Ajaxify a GridView control.Part 1 shows how to create the AJAX enabled grid and to peform sorting and paging operations.Anyone who has used Flickr, GMail, Google Suggest, or Google Maps
will realize that a new breed of dynamic web applications is emerging.Web applications have traditionally been a set of HTML pages that must
be reloaded to change any portion of the content.This article will detail several techniques that you can use today to
enable your web applications to be more rich and interactive like
desktop applications.Java applets, and hidden
frames to emulate this interaction model for some time.Dojo,
Prototype, and the
Yahoo User Interface Library
have emerged to fill in where the browsers are not as manageable and to provide a
standardized programming model.Ajax interactions allow for a clear separation
of presentation logic from the data.HTML documents for every client event resulting in a call
to the server.Load on demand: Based on a client event, an HTML page can
fetch more data in the background, allowing the browser to load pages
more quickly.Ajax techniques to
get a set of current data without reloading a full page.Polling is not the most effecient
means of ensuring that data on a page is the most current.See this blog entry on
Comet using Grizzly
for more on the development of server push with Java technology.See the article on the use of Ajax and portlets for more on how you can use portlet applications today.Ajax interactions
allow web applications to do much more than they have done in the
past.ValidateServlet
will provide the validation logic.Figure 1 describes the details of
the Ajax interaction that will provide the validation logic.The following items represent the setups of an Ajax interaction as they appear in Figure 1.The ValidateServlet returns an XML document containing the result.The HTML DOM is updated.Now let's look at each step of the Ajax interaction in more detail.An XMLHttpRequest object is created and configured.String method, String URL, boolean asynchronous).The callback function for this interaction
is set with the statement req.See
section 6 for more details.When this function is called on the
XMLHttpRequest object, the call to the URL that was set during the
configuration of the object is called.Use an HTTP GET when the request is idempotent, meaning that two duplicate requests will return the same results.The request is processed by the ValidateServlet.URI "validate" checks
whether the user ID is in the user database.XMLHttpRequest just as it would any
other HTTP request.In the case of this example, let us assume that the user typed duke as the ID.The XMLHttpRequest object calls the callback() function and
processes the result.The XMLHttpRequest object was configured to call the callback() function when there are changes to the readyState
of the XMLHttpRequest object.Let us assume the call to the ValidateServlet was made and the readyState is
4, signifying the XMLHttpRequest call is complete.The HTTP status code of 200 signifies a successful HTTP
interaction.The string representation of the XML document that was
returned may be accessed by calling req.This function will call the setMessage() with the
value of the message element to update the HTML DOM.The recommended way to gain a
reference to an
element is to call document.One common means to change the body content of an element is to set the innerHTML property on the
element as in the following example.Ajax applications such as Google Maps use this technique of adding image elements using Ajax calls to dynamically build maps.XML
content needed by the client HTML pages.Dojo,
which provides fallback solutions for making Ajax interactions transparently even on older browsers that
do not support the XMLHttpRequest Object:.Dojo, which addresses many of the differences.Debugging: Ajax applications are also difficult to debug because the processing logic is
embedded both in the client and on the server.When
providing Ajax services, you should take care to make
sure that those services are made available only to those intended.Restricting Access to Your Ajax Services for more
information on protecting your services.We have seen that Ajax interactions can solve many problems.With a better understanding of this interaction model, today's applications can
become more interactive, providing the end user with a better experience.Using Ajax requires that you use the latest browser versions that support the XMLHttpRequest object needed for Ajax interactions.As the Ajax programming model evolves, existing technologies and frameworks will make this transition easier.What is evident is that prominent web applications are increasingly becoming more interactive.The Ajax FAQ for the Java Developer contains resources and links for common
questions and is a good next step for getting started with Ajax.Ajax with the Java EE 5 platform.Visit the
Ajax Developer Resource Center.Read "Ajax: A New Approach to Web Applications" by Jesse James Garrett.Greg Murray is a Sun Microsystems engineer,
the Ajax architect and former servlet specification
lead and a former member of the BluePrints team, where he focused on the web tier and
internationalization.Read more about Ajax and find links to working example applications from this article in author Greg Murray's weblog.Java tools and technologies like NetBeans, JavaServer Faces, Java Studio Creator, jMaki, DynaFaces, Phobos, and more.
