onreadystatechange event?

[oddz]

is onreadystatechange an event?

Is it possible to do something like this:

this.request.addEventListener('onreadystatechange',handler,false);

were this.request is a XMLHTTRequest object.

Yes to all the above, though you may with to include IE in what you're doing as well.

Either with advanced event registration with at least the following

if (document.addEventListener) {
    this.request.addEventListener('onreadystatechange', handler, false);
} else if (document.attachEvent) {
    this.request.attachEvent('readystatechange', handler);
}

Or if you know that the object event won't have more than one function assigned to it, you can use the standard event registration instead.

this.request.onreadystatechange = handler;

Listening for that event isn't working so I just used the standard event registration.
