Why aren't you just using the Ajax.PeriodicalUpdater, which supports
the decay option?
var poller = new Ajax.PeriodicalUpdater('some-element-id', '/foo/bar',
{decay:10});
Also, if you pass an empty string as the first parameter, then you can
pass pure JavaScript to be executed as opposed to just replacing the
contents of a page element.

[Proto-Scripty] Re: PeriodicalExecuter vs. Ajax.PeriodicalUpdater: use cases and advice?
Well since the Ajax requests in Prototype will auto-eval the response,
you can modify the page without updating just one div. It's the route
I take most of the time.
Say you set it up like this:
new Ajax.PeriodicalUpdater('', '/some/url');
Then the response from /some/url could be:
$('some-element').blindUp({duration:0.5);
// wait for the blind up to complete before replacing the content
Element.update.delay(0.5, 'some-element', 'pmy new content/p');
// wait for the blind up to complete, then wait a 10th of a second longer
Element.blindDown.delay(0.6, 'some-element', {duration:0.5});
You get the idea. I find it more flexible and convenient than updating
just a single element. You could alternatively call into some
predefined object/method to do this work.
Some people might be opposed to this approach, but it works.

[Proto-Scripty] Re: One AJAX Script, Three Browser Bugs?
There is no inherit flaws in Prototype that would cause erratic
behavior like you are describing. That's just plain ludicrous for
somebody to suggest that, typical jQuery crowd trying to pimp their
framework at any chance they can ;)
Right away I think your initializer code is buggy. Not sure why you're
iterating over the entire forms collection and then using a regex to
match an ID. Your form has an ID so why not use it? Or if you will
have multiple forms to observe why not just give them all a class name
then you can match just those forms by doing:
form method=... action=... class=poll
...
/form
$$(form.poll).each(...)
Also, you should use a true event observer rather than the onsubmit
attribute, such as:
someFormElement.observe('submit', function(event){ event.stop(); /*
stop the form from being submitted */ });
Also, you are assigning a function to onsubmit, but that function is
lacking the proper scope. I don't see how the code you have would work
in any browser but I guess I'm missing something since you say it
works in IE.
Why don't you try something more like this:
var PollForm = {
initialize: function(){
// for each element that matches this selector, invoke the
// observe method with these arguments
$$('form.poll').invoke('observe', 'submit',
this.formSubmit.bindAsEventListener(this));
},
formSubmit: function(event){
// stop the form from being submitted
event.stop();
// process the form passing in the form relating to the event
this.processForm(event.element());
},
processForm: function(form){
// do whatever you need to do here
var formData = form.serialize();
}
}
document.observe('dom:loaded', PollForm.initialize.bind(PollForm));
See these pages for more info on the various methods used in this example:
http://www.prototypejs.org/api/document/observe
http://www.prototypejs.org/api/utility/dollar-dollar
http://www.prototypejs.org/api/enumerable/invoke

this.interval = setInterval(function(){

I think you will need to use the native methods to get the text nodes
as Prototype filters them out. This will work though:
$A( $('some-element-id').childNodes ).select( function(element){
return element.nodeType == 3; } )
Or better yet:
Element.addMethods({
textNodes: function(element){
return $A(element.childNodes).select( function(child){ return
child.nodeType == 3; } );
}
});
Then you can just do: $('some-element-id').textNodes();

[Proto-Scripty] Re: Disable form submission
To add to the list of ideas, I would recommend you override the
Ajax.InPlaceEditor#checkForEscapeOrReturn method to do what you want
since that's where this submit event is getting fired from.
Ajax.InPlaceEditor.addMethods({
checkForEscapeOrReturn: function(e) {
if (!this._editing || e.ctrlKey || e.altKey || e.shiftKey) return;
if (Event.KEY_ESC == e.keyCode)
this.handleFormCancellation(e);
else if (Event.KEY_RETURN == e.keyCode)
return; //this.handleFormSubmission(e);
}
});
Ideally you would pass in an extra option when instantiating the IPE
and then in the above code snippet you could check for the existence
of an option before blocking the form submit event.
-justin
P.S. Your users might see this as a bug since submitting a form on
return key press is expected behavior.

The Ajax.Request object does not handle nested parameters. You should
use a string instead.
'user[first]=first_nameuser[last]=last_name'
This is happening because the AjaxRequest parses the parameters with
Object#toQueryString which does not parse nested objects.

[Proto-Scripty] Re: $$( ) returns hidden/removed tr tags
If all your HTML and JavaScript is in one file, you can put it in pastie and then provide a link. See here: http://pastie.org/ Since you're using Prototype, you should take advantage of it's helper methods to traverse the DOM, such as Element#up and Element#down instead of messing with parentNode ... especially since the element returned from parentNode won't be a Prototype-extended element when in IE.

[Proto-Scripty] Re: $$( ) returns hidden/removed tr tags
Just as I thought, you are calling your function setRowFeatures
immediately instead of waiting until the row is removed. Due to
implementation problems in browsers like IE, I really recommend
against using effects on table elements.
Take these 2 lines of code:
row.fade(); //{afterFinish: function(fx){ fx.element.remove()}});
setRowFeatures();
And change them to:
row.remove();
setRowFeatures();
If you insist on using an effect to remove the row, you need to wait
until the effect has completed before you process the rows.

[Proto-Scripty] Re: $$( ) returns hidden/removed tr tags
Like I said in my first post, delay invoking your function for the
same amount of time as the effect. There's a few different ways to
achieve this, but the goal is don't do any row counting/alteration/etc
until after the effect is complete.
row.fade({duration:0.5});
setTimeout(function(){
row.remove();
setRowFeatures();
}, 500);

[Proto-Scripty] Re: User types freely on webpage and it jumps to a link...
Yes you could just setup a keyup observer on the entire document, the two problems that I see right away is that any keyboard shortcuts the user already uses may or may not work any longer depending on how you write your code. Secondly, depending on the size of the list of links, the script may take a while to process each keypress. There's a few other issues I'd be concerned with, but the above is probably enough to think about for now. Having a textbox to type into would solve the first problem. Keeping a copy of the list of links in a local variable would help to solve the second problem. -justin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

[Proto-Scripty] Re: autocompleter does not work with contents pasted by using mouse
On Fri, Sep 12, 2008 at 11:57 AM, Jack [EMAIL PROTECTED] wrote: Question 1: I've observed that when copy paste the search string using keyboard in the text box, it displays hints. However, if I copy paste the same stuff using mouse, then the hints are not displayed at all. I think the even is placed on keydown or something. The Autocompleter listens for the keydown event to trigger Ajax request. To accommodate the event you are describing, you could wrap the Autocompleter#baseInitialize method and add an additional mousedown or mouseup listener bound to the same method that the keydown listener invokes. Question 2: I kept minChars to 2 I entered ab in text box, it shows hints for all matching abs. If I enter a (a followed by a space), it does not even invoke anything does not display hint. Is this a bug? Why space is excluded? Any workaround? The reason for this is because the input is stripped (leading and trailing spaces removed) which means that a single character followed by any number of spaces is still considered a single character. The default minChars value is 1, if you're going to be typing a character then a space you might want to just leave the default value instead of using minChars:2. Alternatively, you can override the getToken method to return an unstripped string. -justin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

[Proto-Scripty] Re: Assigning OnClick Events To Options On A Select Menu?
Why don't you just observe the 'change' event on the select? Works in
all browsers, and is the standard method for observing select boxes.
One tip, where you do:
var someNodeList =
$('game_types').getElementsByTagName('option');
var nodes = $A(someNodeList);
nodes.each(
Can really be:
$('game_types').select('option').each(function(options){
});
