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

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.

I implemented my own autocompleter a long time ago. I couldn''t release it because my company technically owns it now. This is the way I did it: Set Up a Timer that start when the textField takes input (onFocus) Save the timer object and destroy it when the user leaves the field (onBlur) The timer should call a function that checks the user''s text.

I subclassed the autocompleter to make it handle the server returning an xml document instead of a bunch of li tags... if you can tell us what you need the autocompleter to do, perhaps we can help you do it. the reason I ask this is because the autocompleter already has that throttling built in, so why reinvent the wheel? (although, if in the end you really do have to reinvent the wheel, just check out the autocompleter''s code and you''ll find a good example) -Jeremy -- Jeremy Kitchen ++ kitchen-RA8HwDor7flnDGu+y90WmgC/G2K4zDHf@public.gmane.org http://ipaction.org/ -- defend your rights to fair use _______________________________________________ Rails-spinoffs mailing list Rails-spinoffs-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails-spinoffs
What we have is this: A search box: ________ Then we have a box where put in all of the results of the search goes: ********************** * * ********************** (The thing with the box is that, if there isn''t anything inside the search box, the results should show all available keywords. So the search box is acting more like a filter i guess.) Then in the box with all the search results, we want to be able to click on a word and have it populate a multiple select box. So whatever you click in the results box ends up in a multiselect box. The multiselect boxes get saved on a receiving page. The results box is really a list of metadata keywords. And the search box really filters that stuff down. The user needs to be presented with all options before filtering, which is different than how i''ve used the ajax.autocompleter before. I hope this makes sense. And thanks for the help.

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). -Thomas Am 23.05.2006 um 20:54 schrieb Mark McCray:> 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.

So did you ever get that working? (i.e. figure out how to display all results before anything has been typed).

He contacted me via email outside of the mailing list. The auto completer in scriptaculous couldn''t provide the functionality he needed. I gave him the general design of what I did way before the scriptaculous auto completer came out. He said thanks and ran I think.

So whatever you click in the results box ends up in a multiselect box. The multiselect boxes get saved on a receiving page. The results box is really a list of metadata keywords. And the search box really filters that stuff down. The user needs to be presented with all options before filtering, which is different than how i''ve used the ajax.autocompleter before. I hope this makes sense. And thanks for the help.
