Use Form.Element.DelayedObserver (which is in script.aculo.us'
controls.js), which does
exactly this (it takes a delay argument to control the amount of time
after typing has stopped,
normally it uses 1/2 second).

Actually,
here's what i'm trying to do:
I want the user to be able to type in some text in an input field
and i only want the ajax request to happen after the user has
stopped typing for 1 or two seconds. Kind of like how google
suggest or autocompleter works. I can't use the ajax autocompleter
because we have a specific requirement that makes the autocompleter
not work for us.
Thanks,

Subject: RE: [Rails-spinoffs] throttling...
In the options argument you have the following options (http://
www.sergiopereira.com/articles/prototype.js.html ) and you will
want to use Ajax.PeriodicalUpdater w/ the last options:
The options argument object
An important part of the AJAX operations is the options argument.
There's no options class per se. Any object can be passed, as long
as it has the expected properties. It is common to create
anonymous objects just for the AJAX calls.
Property Type Default Description
method String 'post' Method of the HTTP request
parameters String '' The url-formatted list of values passed to
the request
asynchronous Boolean true Indicates if the AJAX call will be made
asynchronously
postBody String undefined Content passed to in the request's body
in case of a HTTP POST
requestHeaders Array undefined List of HTTP headers to be passed
with the request. This list must have an even number of items, any
odd item is the name of a custom header, and the following even
item is the string value of that header. Example:['my-header1',
'this is the value', 'my-other-header', 'another value']
onXXXXXXXX Function(XMLHttpRequest, Object) undefined Custom
function to be called when the respective event/status is reached
during the AJAX call. Example var myOpts = {onComplete:
showResponse, onLoaded: registerLoaded};. The function used will
receive one argument, containing the XMLHttpRequest object that is
carrying the AJAX operation and another argument containing the
evaluated X-JSON response HTTP header.
onSuccess Function(XMLHttpRequest, Object) undefined Custom
function to be called when the AJAX call completes successfully.
The function used will receive one argument, containing the
XMLHttpRequest object that is carrying the AJAX operation and
another argument containing the evaluated X-JSON response HTTP
header.
onFailure Function(XMLHttpRequest, Object) undefined Custom
function to be called when the AJAX call completes with error. The
function used will receive one argument, containing the
XMLHttpRequest object that is carrying the AJAX operation and
another argument containing the evaluated X-JSON response HTTP
header.
onException Function(Ajax.Request, exception) undefined Custom
function to be called when an exceptional condition happens on the
client side of the AJAX call, like an invalid response or invalid
arguments. The function used will receive two arguments,
containing the Ajax.Request object that wraps the AJAX operation
and the exception object.
insertion an Insertion class undefined A class that will determine
how the new content will be inserted. It can be Insertion.Before,
Insertion.Top, Insertion.Bottom, or Insertion.After. Applies only
to Ajax.Updater objects.
evalScripts Boolean undefined, false Determines if script blocks
will be evaluated when the response arrives. Applies only to
Ajax.Updater objects.
decay Number undefined, 1 Determines the progressive slowdown in a
Ajax.PeriodicalUpdater object refresh rate when the received
response is the same as the last one. For example, if you use 2,
after one of the refreshes produces the same result as the
previous one, the object will wait twice as much time for the next
refresh. If it repeats again, the object will wait four times as
much, and so on. Leave it undefined or use 1 to avoid the slowdown.
frequency Number undefined, 2 Interval (not frequency) between
refreshes, in seconds. Applies only to Ajax.PeriodicalUpdater
objects.
var myUpdater = new Ajax.PeriodicalUpdater( $('itemId'), url,
{frequency:1} );

Is there a way to throttle the firing of updater requests easily with
Prototype?
Thanks,
