AJAX

Posted 05 February 2009 - 10:23 PM

What forum would we use for AJAX? Java or Web Development? Is AJAX it's own language or is it just a mashup?

It's A-synchronous Javascript And Xml I think. Essentially it's a technique that uses Javascript's (not Java's) xmlHttpRequest() function to communicate with a separate location (often a server side script like php) without reloading the original page.

It's the use of Javascript to work with XML. It has absolutely nothing to do with Java.

Moved to Javascript.

thehat is correct. Ajax is simply a special use of javascript allowing communication calls dynamically within a page.

Okay, so I already knew that AJAX means Asynchronous Java and XML, but you guys are saying that it uses javascript? I am new to Java, but have plenty of experience in HTML and bit in XML and CSS, but absolutely no Javascript. This may sound like a dumb question but what is the difference between Java and Javascript? Isn't JS just a form of Java that you write in an html document? It still calls upon the JRE doesn't it?

Javascript and Java share only the name. THe 2 languages are totally different.

AJAX is Javascript, nothing to do with Java.

Java requires compilation and a ton of other stuff. Javascript only requires a web browser.

A Java Applet is Java in a web page. Applets use the JRE, Javascript uses the built-in browser stuff, not the JRE.

As I stated above, Java and Javascript are COMPLETELY different; only sharing in the name.

I do believe Javascript coined its name to play off of the popular Java, read that somewhere.

Javascript is a client side language, which runs on client side only, the idea of AJAX is allowing an activeX script to send a connection with data to another machine asynchronously. The only reason AJAX has a separate name is because Javascript was not originally intended to allow any connections, but was adapted with activeX to try and create a secure means of doing so. It is of course a failure in the security aspect, but can't blame M$ for trying. While they did it for a selfish reason, they did pioneer it.

Well, I have been learning Java and I know that web apps are the new cool thing to do. So I thought I would try this AJAX thinking it was based on Java. I orderd a AJAX for dummies book, but should I be looking at a Javascript for Dummies first, or do you guys think I will be okay with going straight to AJAX with no JS primer?

Well, ajax is only a small part of Javascript, it doesn't require much knowledge of the language overall, but it is always nice to know the whole language instead of just a part. It is totally up to you, it really depends on how interactive you are wanting to make your site.
