Hello everyone,

I have started some Articles on AJAX on my weblog. I am currently writing AJAX in Action with another author; Dave Crane. I have been getting a lot of questions from the community about AJAX so I thought I would start to give a great overview on AJAX and how it can be used and what to avoid.

The first article on the subject starts here and you can find additional articles after it. If you do not know AJAX has been added to the ASP 2.0 framework so you may want to learn about what is behind AJAX so you can understand how to implement it in your future applications.

AJAX...Is it hype? is the first article with other articles following it in the series.

If you have any questions about AJAX, feel free to ask them here, on my blog, or over on JavaRanch.com; and I am willing to answer them. I have been working with the technology for awhile now and hope everyone looks into it since it can help you build a rich user interface and improve performance if you implemented AJAX correctly!

I have been looking at AJAX and I realized the simpler the better.  If you have time, please evaluate what I consider to be the best implementation of AJAX and .NET.

URL for more information on SAL is at: http://www.codeproject.com/Ajax/SAL.asp

What do you think? The Simple AJAX Library looks great, but the Javascript seems to lack multi-threading.  In my opinion that isn't a problem if exceptions are caught and performance is fine-tuned.  Thanks for your time.   

The javascript would have to lack multi-threading seeing as how javascript does not support it.

the only real thing i am unsure of is the safety of using AJAX, such as ensuring the proper person is logged on

There is no difference between how you implement security on a regular application or an Ajax based one.

Yes, AJAX is just a client-side technique and security logic must reside on server where you can take advantage of security features of ASP.NET.

try ajax.net

first of all. It is best you post this question in the client side web development part of the forum...

now...
What do you mean with "code behind function" ?

do you mean a server side function?
you can send data to an asp.net page with AJAX and then based on the data you get... go to a certain function.
use the following object in javascript.

var xmlHttp = new ActiveXObject("Microsoft.XMLHTTP")


do you mean a javascript function that can parse your xml ?
use the following object in javascript.

var xmlDoc = new ActiveXObject("Microsoft.XMLDOM")

do you want the data, not to be in XML format?

use the setrequestheader method of the XMLHTTP object

Thanks dear for help! I really appreciate the Exact solution provided by u!

Keep up the good work. I bought your book and so far it has been a Really good read. I recommend it to others.

I will gladly check out the article, and maybe post some comments on my own blog. Interestingly enough, I didn't know too much about AJAX, until I heard Jesse James Garrett talk about it at the KM World conference a few weeks back. As he described what AJAX was all about, I was stunned that people are finally realizing its usefullness now. I have written AJAX style applications since 1997! - The code has always been there, but back then no one developing public sites wanted to touch it because of the browser wars.

Well spoken.
When will you post more?

If this is directed to me, if you go through my blog you will see a bunch of stuff about Ajax there.

Eric, I'll go check out your blog. I like reading everything about ajax I can.
