Ajax Examples and Demos (XMLHttpRequest)

XMLHttpRequest is one of modern DHTML's best kept secrets. - Haha, not anymore! Simon Willison offers up a little code that takes an HTML fragment, fetched via xmlhttp.open, and inserts it into an element with a specified id. Some good links and comments follow the article.

Jim Ley provides his overview of the XML HTTP request object, getting into some browser details and detection before providing some examples and getting into using XMLHTTP with google's SOAP API.

Three examples of XMLHttpRequest in use: autocomplete, live search, and live action.

From the site: This library is meant to simplify and unify the code necessary to successfully send and receive simple data via XMLHTTP.

Apples page on the the XMLHttpRequest object, covering object creation, methods and properties in addition to security issues. They build an example for reading XML data, by retrieving iTunes RSS feeds that you select from a dropdown menu.

This article provides an ASP.NET 2.0 angle of Google Suggest along with a short little look at the history of javascript, frames, remote scripting and XmlHttp + XMLHttpRequest.

A nice overview of the history and a good breakdown how the Suggest feature works.

From the site: This is my take on Google Suggest only with Amazon so I've called it "Amazon Zuggest". Head on over and give this a try.

Francis writes "The Javascript runs in the browser and fires every so often, looks for something to search on, it shoots a request using XMLHttp to my webserver, which in turn creates a SOAP message that gets sent to Amazon. They send back the content and it's formatted on the server, then streamed to the browser. All in the blink of an eye.

This is a cool little app. When you are done searching, have a hover over the "History" list in the left hand column... The site comes up a little messy in Firefox...

A neat little script to play with (not sure what it has to do with weblogs especially tho). From the site: It uses Javascript to get data from a remote source and then loads that into a specified target. Whatever content you like to wherever you like on the page.

Thomas Baekdal gets back into accessibility and Ajax. From the site: Let's look at what we can do to turn an otherwise user-hostile XMLHttpRequest application - into a usable one.... An excellent write-up.

Here's an excellent application of the livesearch idea that has been seen around the web. Type in your search (a band name) and the results show up in a nice table below the search box.

From the site: Sproutliner is a free web service that helps you manage your projects and ideas. This tool looks to be very promising, and to be honest you have to try it out to 'get it'. It is a sort of Ta-da list on steroids, so to speak, in that it is very simple yet a user can add to it and tailor it to their needs.

Very cool...

While makaing some excellent points in the article, the little adventure game "The Search For Fonzie’s Treasure" built using Ajax technologies is pretty cool. The author discusses user profiling as an "evil use" of Ajax. I'm not so sure that I would say that it is evil...
