[Proto-Scripty] Re: Progressive update messages from single request
Hi joe,
I think that what you try to do could not be handle with AJAX.request
().
In fact you'll receive control on a callback in the AJAX.request()
when the response is complete in the browser.
What you could do is a pure HTML solution:
create an iFrame inside your page, and set its location to the request
you made, next treat this request in server and use flush() function
to send a part of the response a

i can see where you're going with that, but in those successively
created new Ajax.Request calls, it's generating a new request to the
server, which runs the server-side routine from the beginning, right?
In my concept, the first call commands the server to run all three
steps:
Client Request 1 --
Collect the data (send feedback to client) --
Create the PDF (send feedback to client) --
Attach to an email and send (send final feedback)
End
Where your structure more resembles:
Client Request 1 --
Collect data (send Feedback 1) --
Client Request 2 --
Create PDF (send Feedback 2) --
Client Request 3 --
Attach and email (send Feedback 3)

Am i correct? If so, that works only to the amount of detail i provide
nested invocations of Ajax.Request to check/perform one specific
detail of progress. Keep in mind this is only an example: what if i
need feedback during the attachment process (attaching 1 of 100
files)? For one, it would be nasty to nest that many Ajax.Request
calls, and more importantly, that email object only exists within the
request that creates and processes it. The second request to attach
file 2 of 100 isn't working on the same email object (as i understand
it).
i did find one QA similar to this where it was suggested to use
$_SESSION for the current progress message... The initial Request gets
the server going on the task, and also creates a second Request that
repeats (eg, Ajax.PeriodicalUpdater). That one does nothing more than
check $_SESSION for the latest message (which gets updated by the task
being performed). That feels slightly better to me, despite the
potential traffic overhead for longer requests (hence the {decay}
option, i suppose).
Something for me to chew on, i suppose.

What you could do is a pure HTML solution:
create an iFrame inside your page, and set its location to the request
you made, next treat this request in the server and use flush()
function (in PHP)
to send a part of the response. This could be Looking up your data
and at each server styep, just flush() a dot to indicate progression.
Then continue like this to indicate the progression inside the iFrame.
When finish, just remove the iFrame to indicate it's finished to the

[Proto-Scripty] Slideshow: how to maintain current slide between manual adv and auto adv
This is hard to explain in a short subject line. I have a slideshow that is set to auto advance and can be paused and played, but can also be manually advanced or reversed by click on arrow controls or the image itself. When I manually advance the slides, and wait for the rotation to automatically resume, it advances to what it would have been had I not manually advanced. Say I am on slide 2 and I advance the slide manually 3 times it goes from slide 5 to slide 3 and up from there. I am not sure if I can place my url as an example or not, but it is mysanantonio.com/businessdev/Christmas_Tree_Lighting_and_Parade.html Otherwise I will submit the html directly -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

/select
After that I've processed the form via Ajax and the select was
selected in 'Red' for example, I reset the select tag with:
Form.Element.setValue('works', '0')
This works fine, the select' option is changed, but when I select
'Red' again the change event isn't fired, only works if I select

[Proto-Scripty] Re: Progressive update messages from single request
Hi Joe, It seems to me the simple way to do this is have the first request initiate a process on the server that keeps running when the request completes; the request returns an indicator of the current status and an identifier for the action. Your subsequent requests supply the identifer, which allows the server- side page to check the progress of the ongoing work matching that ID and report back the (new) status.

Here's a more useful approach: http://proto-scripty.wikidot.com/self-contained-test-page From the sound of it, it sounds like your timed-action is written as go to slide 2 (e.g., from slide 1), which assumes that the slide hasn't changed.

[Proto-Scripty] A class called Queue()
Hi guys,
Firstly I said that I am French. I'll try to speak best in English, be
indulgent.
I recently developed a class based on Prototype for a
application web.
I called this class Queue();
This allows you to stack multiple Ajax.Request (or Update) to they are
treated to the chain via the onComplete.
This allows them allows you to do several things at different times.
For example:
function fooBar() {
MyQueue.add(new Hash({update: 'myDiv', idBhv: 'myBhv', myParams:
'foo' }));
MyQueue.add(new Hash({update: 'mySecDiv', idBhv: 'mySecBhv', myParams:
'bar' }));
}
This function will stack 2 behaviors to be implemented immediately one
after the other.
I was wondering if this feature would be added in future version of
prototype? If yes, I can provide code and ideas.
Have fun,
See you

Re: [Proto-Scripty] Re: Change selected option for select tag
Here's an implementation that works in all the browsers I've checked:
var combinator = function(){
$$('select.combo').each(function(elm){
var elm = $(elm);
var texts = ['Choose...'];
var opts = [''];
var sel =
(elm.options[elm.options.selectedIndex].defaultSelected) ?
elm.options.selectedIndex : -1;
for (var i=0; i elm.options.length; i++) {
opts.push(elm.options[i].value);
texts.push(elm.options[i].text);
};
texts.push('Add new...');
opts.push('Add new...');
elm.options.length = 0;
texts.each(function(el,idx){
elm.options[idx] = new Option(el, opts[idx], (idx ==
0), false);
});
elm.options.selectedIndex = (sel + 1);
elm.observe('change',function(evt){
if(this.value == 'Add new...'){
if(!window.bak) window['bak'] = {};
window.bak[this.id] = this;
var ti = new Element('input',
{type:'text',name:this.name,id:this.id});
this.replace(ti);
ti.focus();
ti.observe('blur',function(evt){
if(this.getValue() == '') {
this.replace(window.bak[this.id]);
$(this.id).options.selectedIndex = 0;
}
});
}
})
});
}
I use this to turn select controls into combo boxes, where you can add
a value not found in the list by choosing Add new...
I believe what you need to look at is whether the selectedIndex is
also the defaultSelected. The picker will always show whatever is the
selectedIndex, but on a reload, it will show whatever is the
defaultSelected.

My problem is simple: When I reset the select element the onchange element doesn't fire, the workflow is this: I've a select element with 3 elements: -Select-, Red, Yellow 1) When the page load '-Select-' option is the default 2) I select Red, onchange works fine here 3) After that I reset the select(with selectedIndex = 0 or writing the property) 4) Now the option selected is '-Select-' 5) I select 'Red' again, the onchange event doesn't fire 6) when I select 'Yellow' in the previous step the onchange event works fine Thanks. -- Rubén Dávila Santos. http://rubenonrails.com -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

[Proto-Scripty] Object mashup
Hello
I have problem with my Objects. My object have many props and method,
one of this is td (screen reprezentation of the object). I observe
click event to obj.td where I do many things on this object and change
td (screen reprezentation). My question : how find object where is
attach clicked td ?
Now I setAttribute to td something like obj_id, when td is clicked
first I read this attribute from td, find proper object by this id, do
what to do and finnaly change state of obj.td. This works fine but
when I have very many obj (like thousand), find object takes many time
(find object is longer then do what to do).
Here is simple example :
// example START
Event.observe(window, 'load', function() {
onLoad();
});
var objTrs = [];
var msg = null;
function onLoad(){
msg = document.createElement(div);
msg.innerHTML = Click on cell;
$(document.body).appendChild(msg);
var table = document.createElement(table);
var tableBody = document.createElement(tbody);
table.appendChild(tableBody);
$(document.body).appendChild(table);
table.border=1
for(var i = 0; i 10; i++){
var myTr = {};
myTr.counter = 0;
myTr.tr = document.createElement(tr);
myTr.objTds = [];
objTrs.push(myTr);
for (var j = 0; j 10; j++){
var myTd = {};
myTd.counter = 0;
myTd.td = document.createElement(td);
myTd.td.setAttribute('tr_id',i);
myTd.td.setAttribute('td_id',j);
myTd.td.innerHTML = myTr.counter + _ + myTd.counter;
myTr.objTds.push(myTd);
myTr.tr.appendChild(myTd.td);
Event.observe(myTd.td, 'click', function() {
// find tr object in array
var tr_id = this.getAttribute(tr_id);
var myTr = objTrs[tr_id];
myTr.counter++;
// find proper td in myTr
var td_id = this.getAttribute(td_id);
var myTd = myTr.objTds[td_id];
myTd.counter++;
var msgTxt = you click + myTr.counter + times on this TR
and + myTd.counter + on this TD;
myTd.td.innerHTML = myTr.counter + _ + myTd.counter;
msg.innerHTML = msgTxt;
});
}
tableBody.appendChild(myTr.tr);
}
}
// example STOP
Best regards
maalek

Re: [Proto-Scripty] Re: Check a mouse button
On jeudi 10 décembre 2009, Alex McAuley wrote: MouseMove tracks the mouse. A drag for example uses Left Mouse Click (down) plus Mouse Move Click simply detects the click on an element or page.. If you want to observe mousemove into an element then setup an observer once it has entered for click .. this seems a slight waste of time and memory to setup observers ad hoc.. What exactly are you trying to acheive - perhaps one of us can point you in the right direction... I precisely wants to implement a drag'n'drop feature. I have a set of pictures, displayed in a table as thumbs, and I can move the thumbs in real time using the mouse. For that, I have 3 callbacks: 'mousedown': I start the drag, by storing the src image 'mousemove': I move the thumbs, onlly if the src image has been set 'mouseup': I just reset the src image, so I know that the drag is over But if I release the button outsideany thumbs, the drag remains active, because I can't detect that it ended. There is maybe a better design to do that? -- Frédéric -- You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

Re: [Proto-Scripty] Re: Change selected option for select tag
Try setting the defaultSelected property as well, that might be getting in the way of your select noticing that it's been changed. yourSelect.options.selectedIndex = 0; yourSelect.options[0].defaultSelected = true; Walter On Dec 10, 2009, at 12:15 PM, Ruben.

[Proto-Scripty] Re: Progressive update messages from single request
david: The buffer/flush path seems to be where this solution is heading. Don't ask me why, but iframes rub me the wrong way. With the evolving needs for more streamlined connections, iframes feel like soggy bandaids to me. Given they have a place where nothing else seems to work (Ajax-ish file uploads), but i'd prefer to steer away from them in this case if i can. TJ: That seems like a fairly solid idea. Same general concept of having a second request object checking in on progress that the server reports back, it just gets it from a relatively more reliable source (instead of $_SESSION). Alex: Could you elaborate a bit, or point me to where i can follow up on that? i'm intrigued, but i'm not deeply familiar with using the output buffer effectively. Thanks for the replies! -joe t.

Your subsequent requests supply the identifer, which allows the server- side page to check the progress of the ongoing work matching that ID and report back the (new) status. People use things like this for showing progress bars for file uploads without using Flash, that kind of thing. HTH, -- T.J.

Re: [Proto-Scripty] Re: document.write() vs Element/appendChild()

Re: [Proto-Scripty] Re: document.write() vs Element/appendChild()
I believe that innerhtml is not completely guaranteed to work the same way across browsers, while the Prototype DOM methods are.
