Ajax tutorial

This Ajax tutorial is a term for a type of programming made popular in 2005 by goggle.com and other big web developers. It loosely stands for Asynchronous JavaScript and xml, which sounds like a whole bunch of techno lingo to your average person. In plain words, in this tutorial we show that Ajax can be thought of as JavaScript on drugs.

Ajax- JavaScript on drugs

When JavaScript first came out, people loved all the cool things you could do with the web browser to make it a more user-friendly experience. You could do many things from validation, quirky popup messages; make cool web tools and much more. However, JavaScript had no way of sending information back and fourth between the web browser and the web server.

If you wanted to get any information from a database on the server, or to send user information to a server script like php, you had to make an html from to Get or Post data to the web server. The user would then have to click submit, and then wait for the server to respond, then a new page would load the results. I’m sure everyone has gotten slightly peeved for having to wait for especially slow websites.

Ajax attempts to remedy this problem by letting JavaScript communicate directly with the server, using a special JavaScript object such as xmlhttprequest. With this object, you could have JavaScript get information from the server without having to load a complete new page.

Is that it then?

Yes that is pretty much and shown in this ajax tutorial. By using the programming practice termed “Ajax” you will be able to trade data with a server, without having to open a new page. Instead of Ajax being seen as “the new way to develop websites,” it should be known instead as another weapon to your programming tools.

This ajax tutorial will introduce you to the basics of Ajax and show you how to send and receive the data from the server without having to use the submit button approach.

Ajax – recommended knowledge

Ajax can be quite confusing unless you have a little prior web programming experience. It is highly recommended that you be familiar with html and JavaScript before trying to attempt this tutorial, or it will probably be nothing but confusion and a waste of your time. Ajax is an asp.net internet protocol. There are several different kinds of internet protocols in ajax tutorial and you have to make sure that you don’t confuse one for the other.
