subject: Tutorial Of Ajax And Flash [print this page]

Ajax is a catchy name for a type of programming made popular in 2005 by Google and other big

web developers. Ajax loosely stands for asynchronous JavaScript and XML, but that just sounds

like techno jargon to many people.

AJAX or more commonly Asynchronous JavaScript and XML cannot be defined a new programming

language; instead it can be termed as a new and innovative way for using existing standards.

In simple words, it can be defined as the art of exchanging data with a server followed by

updating parts of a web page without reloading the entire page.

Before you proceed, make sure that you have a thorough idea about:

HTML / XHTML

CSS

JavaScript / DOM

Some of the applications that make use of AJAX include-

Google Maps

Gmail

YouTube

Facebook tabs

AJAX is based on Internet Standards and prefers using a blend of

XML Http Request object (for exchanging data asynchronously with a server)

JavaScript/DOM (for displaying or interacting with the information)

CSS (for styling the data)

XML (often used as the format to transfer data)

Ajax is only a name given to a set of tools that were previously existing.

The main part is XML Http Request, a server-side object usable in JavaScript, that was

implemented into Internet Explorer since the 4.0 version.

In Internet Explorer it is an ActiveX object that was first named XMLHTTP some times, before

to be generalized on all browser under the name XML Http Request, when the Ajax technology

becomes commonly used.

The use of XML Http Request in 2005 by Google, in Gmail and Google Maps has contributed to

the success of this format. But this is the when the name Ajax was itself coined that the

technology started to be so popular.

In the year 1997, Macromedia acquired the small organization which developed Future Splash as

their own unique way for complementing director, its flagship product. Towards the later half

of the 1998, as much as forty percent of surfers were eligible to view Flash movies

straightway. Soon after this, say within a year, the percentage increased to ninety percent

and today it is going great guns.

Macromedia's popular application Flash has redefined the way web developers approach web

design. With flash the web developer is now able to create a user experience that is rich in

media and relatively quick loading, especially compared to traditional methods like GIF

animations. Websites made up of music, videos, and custom, graphic intensive interfaces are

all possible with Macromedia Flash.

Flash is defined as multimedia graphics program particularly for use on the web

Flash helps you in creating interactive movies online

Flash make use of vector graphics that implies that the graphics can be scaled to any

desired size without losing quality or clarity

Flash doesnt need programming skills and it is simple to learn as well
