thanks!
I was working (for studies purpouses) on a hand made auto-complete with
prototype, the idea was that if the user types too fast it will launch only
the latest request not all of them.
Another issue i was having.. is that if I trigger two or more requests that
will work on the same element, but in different functions, I need them to
occur in a certain order.. is that possible?

Instead of trying to keep the last reference to the XHR sent, just
enforce a singleton style approach, such that the user can't request a
refresh of data when a request is already pending.
function fireAjax(){
if(Ajax.activeRequestCount == 0)
new Ajax.Request(...);
}

Hi Ricardo,
You need to evaluate the transport.readyState of the previous
Ajax.Request, and accordingly decide what you want to do.
Basically, 1|2|3 readyStates mean the the request is still in
progress. If you want to abort the old request, just call
myRequest.transport.abort(); and carry on with creating a new
Ajax.Request.
Personally, I prefer to give the priority for old requests.
Anyway, it all depends
*
var myRequest;
function fireAjaxRequest() {
// previous request still running
if(myRequest && myRequest.transport.readyState.search(/^1|2|3$/i) > -1)
return;
myRequest = new Ajax.Request(..);
}
*
cheers

Getting in the road with the question. I have assigned the Ajax.Request to a variable, but in the ajax request code i've add an onSuccess function to be called. This will be called multiple times if I make multiple requests? or just the last one will be completed? :: Ricardo Verhaeg :: Bacharelado Ciências da Computação - USP - São Carlos (2005) On Mon, Nov 17, 2008 at 09:53, Alex Mcauley <[EMAIL PROTECTED] > wrote: > > you can assign the request to a variable > > myRequest = new Ajax.Request(.. > > > - Original Message - > From: "Manish" <[EMAIL PROTECTED]> > To: "Prototype & script.aculo.us" < > prototype-scriptaculous@googlegroups.com> > Sent: Monday, November 17, 2008 9:09 AM > Subject: [Proto-Scripty] new AjaxRequest. > > > > > > Whenever we do new AjaxRequest a new activeX object is created and > > sent to the url.
