any good javascript ajax class ?

[PHPycho]

Hello forums!
Can anybody refer a good javascript Ajax class (with loading page effects more preferrable(wink)),
which can be used with just creating objects and with minimal amount of code?

Thanks in advance for the help.

Not sure if that's the sort of thing you're looking for.

I use Mootools for that kind of thing. With it you can refresh a portion of your DOM with some AJAX in one line:

var myAjax = new Ajax(url, {method:'get',update:'mydiv'}).request();

adding a pretty loading graphic is easy too
