251 of 317 | Cross-Domain XML - Like it or not, there's plenty of people who want to do cross-domain remoting. The typical technique is via script tags, and since this means the response must be valid Javascript, JSON is usually the message format. But what if you want to grab some XML instead of a JSON-formatted object? Dave Johnson explains how [...]...

252 of 317 | Two kinds of AJAX: HTML++ vs Client / SOA - On the SitePoint PHP Blog, Harry Fuecks discusses what he sees as the two types of Ajax applications out there - "HTML++" and the standard "Client/SOA" model. Think this needs stating clearly, following the comment from Bill Edney on of technicalpursuit (Tibet), and because I think it reflects experiences people are having with AJAX. In short think [...]...

253 of 317 | Transforming JSON - Stefan Gössner has seen a need to transform the JSON format, similarly how we transform XML via XSLT. The implementation of JSON/T is by writing rules in JSON format itself. Example Given a JSON object such as: { "link": {"uri":"http://company.com", "title":"company homepage" }}   and transform it to: company homepage   The JSON/T rule for doing this: { "link": "{link.title}" }   You can download [...]...

It walks through creating An Atlas ASP.NET application from scratch, creating a Web service for the backend, and Atlas JavaScript for the front end. The Atlas Magic It allowed us to write the web application without us making [...]...

255 of 317 | Ideal Ajax data format? - The quirky PPK at quirksmode asks: Once you’ve succesfully fired an AJAX request, what sort of response should the server give? An XML document? An HTML snippet? A JSON string which is converted to a JavaScript object? Or something else? In this entry I’d like to discuss the three formats, with examples, and ask you which [...]...

256 of 317 | Brad Neuberg: render UI On The Server or the Client? - Brad Neuberg has a post worth reading on where to render the UI for ajax apps over on his blog. He talks about two general approaches you can take: Thick Client - basically the server just gives you answers to RESTful web service calls, and your client side code has its own mini-MVC approach so [...]...

Well, XML for ASP posted the strangely named "Using Atlas to View Customers". It has sample code and a video presentation of a demo app using Atlas to retrieve customer data via a web service, using ajax techniques of course.The video [WMV, 10 megs] is about ten minutes long and demonstrates the Atlas controls for things like autocompletion and a Virtual Earth component. Or you can grab the code, which you`ll need the Atlas preview release to run it....

271 of 317 | Ajax-S: Ajaxian slideshow software - Robert Nyman has released an AJAX-based slideshow package called Ajax-S.What about Eric Meyers S5 I hear you cry!Robert mentions that:The idea came to me because I wanted a lightweight slideshow based on HTML, CSS and JavaScript, but I also wanted to separate the data of each page from the actual code that presents it. Therefore, I decided to move the data into an XML file and then use AJAX to retrieve it. The name AJAX-S is short for AJAX-Slides (or Asynchronous JavaScript and XML Slides, if you want to).Naturally, one of my inspirations for creating a HTML-based slideshow are from Eric Meyer and his S5. However, I wanted to take it one notch further, to make it more flexible and also usab......

This time it is on Ajax with Direct Web Remoting.Exciting as it is, adding Ajax functionality to your applications can mean a lot of hard work. In this third article in the Ajax for Java developers series, Philip McCarthy shows you how to use Direct Web Remoting (DWR) to expose JavaBeans methods directly to your JavaScript code and automate the heavy-lifting of Ajax.The article walks you through an example, a minimal model based on an online store.Exposing Remote CallsThe magic of remoting with DWR is mainly in the XML config. ...

273 of 317 | Solutions to allow XMLHttpRequest to talk to external services - Over on XML.com they published Fixing AJAX: XmlHttpRequest Considered Harmful.This article discusses a few ways to get around the security constraints that we have to live with in the browsers theses days, in particular, only being able to talk to your domain via XHR.The article walks you through three potential solutions:Application proxies. Write an application in your favorite programming language that sits on your server, responds to XMLHttpRequests from users, makes the web service call, and sends the data back to users.Apache proxy. Adjust your Apache web server configuration so that XMLHttpRequests can be invisibly re-routed from your server to the target web service domain.Script ta......

274 of 317 | Streampad: Ajaxian Music with Mashups - Daniel Kantor just released a very interesting ajaxian web service called StreampadStreampad allows you to listen to your own music streamed from home to any web browser. It uses an Ajax interface and Flash to play the music. It includes mashups with google maps (see what others are listening to), del.icio.us (grabs mp3 links from del.icio.us), amazon (cd cover art), and the live music archive (live concerts).It is great to see an Ajax interface that isn`t scared to use Flash where it makes sense, yes use the power of open standards too, and integration to other web services.Check out a demo of the playerGreat job Daniel!...

276 of 317 | Ajax Patterns Reader - Michael Mahemoff is a busy man on the patterns side of Ajax, and even ended up with the typical Ajax example: an ajax patterns reader!The reader grabs the AjaxPatterns.org content and presents them Ajax-style. You actually queue up patterns in a playlist and click "Next" to "play" them. Yeah, a bit contrived, but it helped illustrate quite a few patterns! If I have time, I`d like to enhance it into a proper reader, and also offer an easy interface to leave feedback, which would be automatically appended to the wiki`s Discussion tab for that pattern.Michael then created a ghost enabled version that uses the Service Test pattern.Diagnosis PatternsLogging Instrument your Javascript with log me......

277 of 317 | Monkeygrease: Greasemonkey Inverted - If you`ve attended one of our Ajax talks or listened to our Podcasts, you know that we`re big fans of Greasemonkey, the little Firefox plug-in that lets you modify web applications.Rich Manalang recently pinged us about Monkeygrease, which he describes as:basically a server-side Greasemonkey for J2EE web appsIt`s a servlet filter (sorry for the Java speak) that lets you decorate your web pages as they are served up. This is incredibly useful for "COTS" (commercial, off-the-shelf) applications deployed in your company that you want to tweak with a bit without reverse engineering (e.g., JIRA).After installing the filter, you specify the injections via a special XML file:Very cool, Rich!...

278 of 317 | Ajaxian To Do Lists programmed with XForms - Erik Bruchez of Orbeon has put together an XForms based To Do list application. It implements a dynamic user interface for To Do lists done 100% with XForms, on top of the open-source-Ajax-enabled OPS XForms engine. This example illustrates many XForms features, such as:Nested xforms:repeatUse of "relevant" for conditional display of controlsTyping which allows for automatic formatting of datesUse of xforms:submission with instance="replace", here to call a service able to format an XML document into HTML.Use of multiple instancesUse of xforms:setfocus and xforms:setindexCheck out the applicationCheck out the the formatted source code ...

279 of 317 | Taconite 1.0 Released - Ryan Asleson and Nate Schutta have released Taconite 1.0.What is TaconiteTaconite is an Apache-licensed open source framework that is based on concepts from the W3C DOM Level 3 Load and Save specification. Taconite aids in the development of Ajax-enabled applications by allowing the developer to specify new or updated content as XHTML. Taconite automatically updates the current Web page`s DOM based on the XHTML supplied by the developer. As such, Taconite eliminates the need to write document.createElement and document.appendChild statements to update the DOM following an Ajax request. Better yet, Taconite takes care of the quirks that exist among modern browsers. Have you ever tried to......

285 of 317 | Ajax for Mobile Devices: MIL - Over on the Moblets blog they are talking about MIL as an option for ajax architectures on the mobile phone.Moblet Instruction Language (MIL) is a declarative language that enables a developer to author a cross-platform mobile applications (a.k.a. Moblets) using only XML, Script, and XPath. MIL is compiled into byte-code by a hosted gateway server and delivered to any device capable of running the Moblet Runtime Environment (MRE). Data requests from a device can be defined synchronously or asynchronously using the and tags declarations. These services are invoke in response to events trigged by the system and the results are then "data-bound" to UI elements using an XPath expression synta......

286 of 317 | Benchmarking XHR vs. IFRAME, and a Neat Hack - Now that so many toolkits abstract away the transport used to make Ajaxian requests, one might wonder whether it matters if XHR or a hidden IFRAME is used to communicate with a server.Emil Eklund tackled that question way back in April:More then anything XML HTTP has enabled developers to make background HTTP requests a lot easier, and a lot faster. It does, however, raise a whole lot of questions; How much faster Is it always faster How about cachingHis conclusionThis clearly demonstrates that XML HTTP is a lot faster than using a hidden iframe for small requests, most likely due to less overhead. As the filesize is increased the advantage obviously shrinks, as the majority of the time is ......

287 of 317 | Java object serialization for Ajax - IBM developerWorks has a nice Java-based Ajax article: Java object serialization for Ajax:If you`re doing Java Web development using Asynchronous JavaScript and XML (Ajax), then delivering data from the server to the client is probably your top concern. In this second article in the Ajax for Java developers series, Philip McCarthy walks you through five approaches to Java object serialization and gives you all the information you need to choose the data format and technology best suited to your application.Philip walks through producing XML (manually and via binding frameworks), using page templating, not using XML, and then JSON:public JSONObject toJSONObject() { JSONObject json = new JSO......

SynchroEdit also supports a simple, text-only editor for more basic documents. To clarify the multiuser experience, the editor window clearly depicts every user`s changes in......

289 of 317 | SPARQL over Ajax - Kendall Clark got a little kiddy thinking about how Ajax and SPARQL can fit together: "SPARQL over AJAX just by itself is so cool it gives me a headache!".SPARQL could be the begining of the merge of Web 2.0 and the Semantic Web. Currently the idea of mash-ups is a big one. How many Web 2.0 apps these days say "integrate with Google Maps, Craigslist, eBay, and Amazon!".Sure, we can try to do all of this work via special web services for each app, but that isn`t giving us a great way to query between them. Enter SPARQL, a query language and protocol for RDF. Don`t get scared by the RDF part, SPARQL can work fine across REST. Here`s a query for fun:SELECT who g mboxFROM FROM NAMED FROM NAMED ......

290 of 317 | War of the Web: Revenge of the Dynamics - As I was watching "24 hour party people" on DVD, I heard the main character talk about the ebbs and flows of the music business. He is talking about the scene in Manchester at the end of the 70`s, and into the eighties. Moving from Joy Division to Happy Mondays and New Order.I think that we are in a new chapter for the web, and as is often the case, the wheel of time is repeating history for us.There are a few dimensions to the current war though. They are on the client side (DHTML Ajax vs. simple HTML vs. Flash/PDF vs. XAML) and on the server side (Rails vs. Java vs. PHP vs. .NET).Let`s start at the beginning.Perl: Birth of CGIDo you remember how the web changed as it moved from static HTM......

297 of 317 | Microsoft Atlas Details Revealed - I`m here at Microsoft`s Professional Developer`s Conference, and they`ve announced some interesting tidbits about Atlas, their Ajax framework. (It was a bit weird to hear Jim Allchin refer to DHTML as Ajax on-stage.)Atlas will be a cross-browser JavaScript library with ASP.NET bindings. They are fully supporting Safari, Firefox, and Internet Explorer. Atlas includes a bunch of UI components as well as other utility functionality (for example, a ScriptManager that loads JavaScript on demand).The idea is that Atlas seamlessly fits into the Microsoft UI client stack: DHTML -> Atlas -> ActiveX -> WPF/E -> Win32 -> WinFX. (WPF/E is the portable Avalon API I blogged about earlier today, WinFX is ......

299 of 317 | Safari 2.0.1: No longer an Ajaxian pain - Mention Safari to many JavaScripters, and they sigh. Look at many frameworks, libraries, and components, and you don`t see Safari on the list of supported browsers half the time.Alex Russell sees some hope with Safari 2.0.1 and maybe beyondAfter much discussion recently with Erik, we decided that Safari was a lost cause when it came to coercing XML documents out of serialized strings. Fortunately, Safari 2.0.1 seems to now include both the DOMParser and XMLSerializer classes that Mozilla implements. Looks like some of the last chinks in Safari`s Ajax armor are finally fixed....
