Just so all of you people know, the WYSIWYG Editor for popular board softwares such as vBull don't use AJAX to init. the Editor, rather... it's a Java Applet used through JavaScript, but not AJAX.

FYI, the vB quick reply currently uses AJAX technology to post.

Isn't AJAX and Javascript quite the same, only a bit extended one? Or am I false informated...

AJAX uses Javascript and XML to do what it needs to do.
For instance, when you are viewing a page generated by AJAX, the javascript makes the php page run and display the outcome in XML and from there, the javascript grabs the XML and displays it however you want it displayed.

My first AJAX script didn't use XML, and it had a few problems... so now I use all XML for the display.

Yes and no.

AJAX is a term that was coined for one way of using some existing technologies (Javascript's XmlHttpRequest Object and XML) to make asynchronous (ie. without refreshing the entire page) GET and POST requests back to the web server and receive data back.

Which is why it's so useless when people come here and say "phpBB needs AJAX" as a feature request as it means nothing inherently.

The same asynchronous behaviour can be achieved using other technologies too (flash, vbscript, java applets, etc. I believe).

I'd like to see an AJAX mouseover of topics, that'll display the first X lines of a post.

Why would you need ajax to do that? that would be to slow.
It's best to just use a tooltip. Even VB only uses a tooltip.

On the whole AJAX is useful, but not too useful and not quite all the time.

Only good ajax-features I've seen have been cron-execution without browser status loading... and the edit button already mentioned in this thread.

cron execution? of what sort? I wouldn't think that a cron would have to be called by Javascript since it's already being called when you load the page via php.

Does something display automatically?
