Filed: Wed, Mar 28 2007 under Programming|| Tags: ajax synchronous javascript post get For almost every situation under the sun, moon, and stars above you will want to use Asynchronous Ajax -- that is just a given. There are, however, some situations where Synchronous Ajax is mandatory, so it can be worthwhile getting a basic handle on how this technology works. Asynchronous AJAX Asynchronous AJAX will initiate a request for a file and then return control to the browser until, at some undetermined point in the future, the server finishes transmitting the request to the browser. If anything goes wrong in the request and/or transfer of the file, your program still has the ability to recognize the problem and recover from it. Synchronous AJAX (SJAX) Synchronous AJAX (Really SJAX -- Synchronous Javascript and XML) is modal which means that javascript will stop processing your program until a result has been obtained from the server.
How to code a Synchronous AJAX function Conclusion. Web 3.0: When Web Sites Become Web Services. Today's Web has terabytes of information available to humans, but hidden from computers. It is a paradox that information is stuck inside HTML pages, formatted in esoteric ways that are difficult for machines to process. The so called Web 3.0, which is likely to be a pre-cursor of the real semantic web, is going to change this.
What we mean by 'Web 3.0' is that major web sites are going to be transformed into web services - and will effectively expose their information to the world. The transformation will happen in one of two ways. Some web sites will follow the example of Amazon, del.icio.us and Flickr and will offer their information via a REST API. Others will try to keep their information proprietary, but it will be opened via mashups created using services like Dapper, Teqlo and Yahoo! The Amazon E-Commerce API - open access to Amazon's catalog We have written here before about Amazon's visionary WebOS strategy. Why has Amazon offered this service completely free?
