hi again,

since some of our fellow residence here have asked me “what the hell is ajax all about ? “, i think i should share some of my early discovery in ajax with all of you. Btw, im not an ajax guru, therefore i would try to explain it in layman terms.

So what is ajax?

ajax in plain word is a technology that enable users to submit or update their web form or web pages without having to reload it at all. Ajax can be a self updating javascript event or a user triggered javascript event in which a user will not experiencing page reload upon submission of request via form submit, or a javascript reload.

Show me the application?

ajax application can be found on most public web sites like yahoo mail and google mail. If you notice, all interactions with the database doesnt require the web page to reload at all. Only, some component will be refreshed. And this have given a lot of benefit to the end user and the application owner.

What is the benefit of applying this ajax thingy on my web project?

the most benefit comes from the fact that only portion of the web page is reloaded. For a big application like yahoo mail, it does save them a lot of bandwidth to begin with. just imagine, the amount of time it takes to reload the whole website and the time it takes to reload a small portion of it.

the next important thing is, since it uses mostly javascript events, the end user will notice an enhance visual experience of the page itself. the level of interactivity is raised to the level of rich client application, same as using java swing or visual basic applications.

last word

ajax is not a new technology, it has been there for years but its adoption have been slowed down by the motion that programmers were getting rid of rich client thin server application architecture. everything has to be web but again, with the ever increasing of ajax, the client is getting fatter from day to day.
