[Proto-Scripty] Re: $F() cannot get radio button values?
I found a solution in the following link
but is that means $F is only for textbox?
http://proto-scripty.wikidot.com/prototype:tip-fetching-radio-button-value
Element.addMethods('form',{
getCheckedRadioValue: function (formElement, name) {
formElement = $(formElement);
var checkedElement = formElement
.select('input[name='+name+'][type=radio]') //gather all radio
inputs with provided /name/
.find(function(inputElem){ return inputElem.checked;}); //find
first checked element
if (checkedElement) {
return checkedElement.getValue(); //return iths value if found
} else {
return null;
}
}//end of getCheckedRadioValue
});

Should I use the old method document.form.xxx[0].checked to check the

[Proto-Scripty] Event onDrop on Sortable class
Hello, I am using the Sortable class for handling drag drop between 3 different columns. In my code, I would like to trigger some method calls just after the drag is ended. I was then looking for an onDrop option, but it doesn't seem to be taken into account. Is this option supposed to be handled by Sortable, if not, do you have another option that could help ?

[Proto-Scripty] Re: problems with observe mouseover and mouseout
I have a realy similar issue as this one, but more on the mouseout
event. Effectively, if I observe a mouseout on a ul, every time my
mouse goes from one li to the other, a mouseout event is triggered.
I tried to make a check in the target function to see which element
was doing the call, but I didn't always receive the ul...
Is this how it's supposed to be done ? Has anyone an example somewhere
of a mouseout use (on an element with children elements) ?
Kind regards,
Christophe

Hello everyone.
I've basically got this HTML code:
ul class=superlist
li class=foo id=bar
div class=foobarsome content/div
div class=contentsome more content/div
div class=actionssome actions/div
/li
/ul
and this JS code:
$$(.superlist li).invoke(observe, mouseover, function(event) {
alert(event.element().inspect().escapeHTML());
});
So now the thing is, that the event.element() method does NOT (as I
would expect) return the li element, but any of the nested elements
instead. Which might be a div class=foobar or a div
class=content.
That results in two problems for me:
1. I want to toggle the visibility of li.actions for the li hovered.
It shall become visible on mouseover and unvisible onmouseout. That
doesn't work since anytime I move over one of the li's nested
elements, the mouse-events get triggered. Although (from my point of
view) I'm never leaving that element, since they are indeed children
of the li.
2. (similar to the first one) I do always need to know which li
element was hovered (so that I can determine which .actions div shall
be toggled but don't know any good way to achieve this.
I've run through similar problems like this several times but could
never find a good solution.
Hope anyone here can help me out :-)

[Proto-Scripty] Re: problems with observe mouseover and mouseout
Hi,
I have a realy similar issue as this one, but more on the mouseout
event. Effectively, if I observe a mouseout on a ul, every time my
mouse goes from one li to the other, a mouseout event is triggered.
That's right, that's how mouseout is supposed to work, but it's a real
pain.
What you probably really want is mouseenter and mouseleave, rather
than mouseover and mouseout. mouseenter and mouseleave are IE-only
events (yes, IE does some things better than other browsers), but
Prototype 1.6.1 (currently on Release Candidate 3[1]) emulates them on
all supported browsers. If you can't use 1.6.1 yet (and there are
outstanding issues), you might be able to study the code to see how
it's done. Basically, it's a matter of checking (via
event.relatedTarget) whether the mouse is going out from one
descendant element to another (or from a descendant back to the main
one) and ignoring that; similarly, if you're doing mouseovers, when
handling them you need to check whether you're seeing a mouseover for
the element you're already over (since mouseover happens repeated as
the mouse moves over the element).

[Proto-Scripty] support for svg element?
Hello all,
This is my first time here. I've been using prototype.js for several
years now, and still love it :-) I've recently found a project named
Raphaël (http://raphaeljs.com) and started playing with it.
But I have a problem with the canvas svg element used by Raphael. I
don't know a lot about the way Firefox lets us embed svg elements
inside html documents, so I was surprised to find that
Element.viewportOffset doesn't work, or any other Position methods for
that matter, while event handlers and several other js things work as
usual.
Take a look at this test page for Firefox 3.5:
!DOCTYPE HTML PUBLIC -//W3C//DTD HTML 4.01//EN http://www.w3.org/
TR/html4/strict.dtd
html
head
title/title
script type=text/javascript src=http://ajax.googleapis.com/ajax/
libs/prototype/1.6.0.3/prototype.js/script
script type=text/javascript
Event.observe(window,load, function (e) {
var canvas = document.createElementNS(http://www.w3.org/2000/svg;,
svg);
canvas.setAttribute(width, 512px);
canvas.setAttribute(height, 342px);
$(container).appendChild(canvas);
alert(Element.viewportOffset(canvas));
alert(Element.viewportOffset($(test)));
});
/script
/head
body style=margin:0px
div id=container style=padding:10px;margin:20pxdiv id=test/
div/div
/body
/html
Why can't I get the offset of the canvas element? Is there a fix or a
workaround? What is special about the SVGSVGElement?

[Proto-Scripty] Re: IE8 invalid argument line 4501
This will reproduce the issues sometimes (http://pastie.org/565352),
but it is not consistent. In principle its the same code that cause
the invalid handeler at line 4501, but it only produces the issue
occationaly. When running it causes a stack overflow at first, and
then produce the error at line 4501.
var CrashDemo = Class.create({
initialize: function() {
document.observe('dom:load', this.dummyMethod());
},
dummyMethod: function() {
var test = $('demo');
test.removeClassName('name');
}
});
Seeing how the original script does not behave the same way as
yesterday, though it still produces this crash occationaly, I am
starting to suspect that it is my system that somehow is the root
cause of this problem.
The above code seem to work as expected on FF, Opera and Chrome.

Can you post a small, self-contained, complete example demonstrating
the problem? (Perhaps usinghttp://pastie.orgfor formatting.)

I encountered this error in all versions of IE8 without non-alpha IDs.
After a lot of debugging and head scratching i discovered that if you
register an observer on the 'dom:load' event in a constructor
(initialize) thats supposed to fire one of the object methods (like
'this.recolour()') it will end up as an infinite loop in IE6, IE7 and
IE8 causing IE to report a stack overflow and invalid argument at this
line.
This is the closest i could find to a thread on this problem, so i am
writing up my discoveries here just in case other developers encounter
this.
This behavior was present in Prototype 1.6.0 and at least 16.1rc3,
these are the versions I've worked with.
Best regards,

We've having this exact error with IE8 and it's always related to

Doing something like adding and underscore to the id fixes the
problem.

[Proto-Scripty] Eventchain click and drag
Hello everybody,
another problem occured while coding complex stuff.
I try to bind 2 events on one Element like this:
this.Dragger = new Draggable($(this.widgetToolId),{revert:
this.shallIToolRevert.bind(this), onStart:this.startDrag.bind(this),
onEnd:this.stopDrag.bind(this), change:this.whileDrag.bind(this),
onDrag:this.whileDrag.bind(this), ghosting:true, starteffect:null});
$(this.widgetToolId).observe('click',this.toolClick.bind(this));
This works fine on FF but won't work on IE. The Exploder seems to
think that a click is a very short drag without movement.
If I'm using mouseup as listener this works fine, but then alway BOTH
events are fired.
Is there anyway around?

Quite a few errors there, first off you are naming the function, you
cannot do that if you are using a function literal. Secondly for
Effect.Appear you are probably best off using it directly on the DOM

parentheses are incorrect. The following should work (though I
drycoded it).
document.observe(dom:loaded, function() {
$('show').Appear({ duration: 3.0 });
});
I'm not 100% sure that Effect.Appear will work properly with an inline
style like that, if not then remove the inline style and call the
document.observe thusly to hide it before rendering and then fade it
in over 3 seconds:
document.observe(dom:loaded, function() {
$('show').Hide();
$('show').Appear({ duration: 3.0 });
});
Thank you DJ, you did get me going in the right direction. After much much
MUCH hacking away I finally got this code to work:
Event.observe(window,'load', function() {
Effect.Appear('appear', { duration: 7.0 });
});

[Proto-Scripty] Re: Any javascript included in document loaded in div with Updater isn't recognized
Hi, You're looking for the evalScripts option of Ajax.Updater[1], which in turn uses Element#update[2] to update the target container, which in turn (!) uses String#evalScripts[3] to eval the scripts. Scripts must be inline in script tags, they cannot have src attributes loading external scripts. If you want to do that, there's an article[4] on the unofficial wiki that talks about how to do that. [1] http://prototypejs.org/api/ajax/updater [2] http://prototypejs.org/api/element/update [3] http://prototypejs.org/api/string/evalScripts [4] http://proto-scripty.wikidot.com/prototype:how-to-load-scripts-dynamically FWIW, I suggest giving the API a good front-to-back read. Takes about an hour, and will save you lots of time and trouble in the long run. HTH, -- T.J.

[Proto-Scripty] Re: Using a prototype function in dynamic content.
Ok, thanks. I think I understand the reasoning here, but I can't get
my actual example to work.
This is the script as it appears in the initially loaded page and also
as it is in the html snippets bought in by ajax.
div id=kwdisp0101some keyword/div
script
if(editor0101){
editor0101.dispose();
editor0101 = undefined;
}
var editor0101;
editor0101 = new Ajax.InPlaceEditor('kwdisp0101','./addkw.php',{size:
17,callback: function(form, value) { return 'oldwd=some
%20keywordidx=section-idmyparam=' + escape(value)}});\n;
/script
The 0101 is an example, I do this for each keyword in the list and
derive the numbers from some php code, net will be 0102, 0103 0201
0202 c. This goes for both the editor var name in the js, and for the
dic id in the HTML.
Have I missed or misunderstood something? (it's been a long day...)

[Proto-Scripty] Re: Using a prototype function in dynamic content.
Hi,
Really close. :-) But you're running afoul of how eval handles the
var statement. (If you'd just left the var statement out entirely, it
probably would have worked thanks to the horror of implicit globals
[1], but you'd be cluttering up the window namespace something
fierce.) Also, you're repeating a lot of code.
Instead, I'd suggest declaring a hash of editors on your main page
(not the stuff loaded dynamically) and a function for adding or
replacing one; and may as well wrap those up into just the one global
symbol:
In your main script:
* * * *
var ipeManager = {
editors: {},
addOrReplaceEditor: function(id, url, size, paramstr) {
var eds;
eds = this.editors;
if (eds[id]) {
eds[id].dispose();
eds[id] = undefined; // Or: delete eds[id];
}
eds[id] = new Ajax.InPlaceEditor(
id,
url,
{
size: size,
callback: function(form, value) {
return paramstr + escape(value);
}
}
);
}
};
* * * *
Then the dynamic stuff can be much simpler:
* * * *
div id=kwdisp0101some keyword/div
script
ipeManager.addOrReplaceEditor(
kwdisp0101,
'./addkw.php',
17,
'oldwd=some%20keywordidx=section-idmyparam='
);
/script
* * * *

Thx in advance !

[Proto-Scripty] Re: ternary operators
Hi Alex,
However it cannot be achieved so it must be done usung if/else..
Well, this is JavaScript, there's almost always a way. I can think of
four off the top of my head that keep it in a single expression -- but
all of them are much worse (most of them much, much, much worse) than
using an if/else. ;-) The four are:
1. Massage the return value of the first thing you want to do to force
it to be the return value you want. Actually, in your specific case,
you don't have to anything:
return $(arg) ? true : alert('Element Does not exist');
alert has no return value, hence your function returns either true or
undefined, which is good enough for anything branching on its return
value (undefined is falsey, after all). If you really want a false,
use !! to force it.
Blech.
2. If you wanted to return something other than false, and if the
first part has an invariant result, you could manipulate that return
value to be falsey and use the OR operator, which is much more
powerful in JavaScript than in most languages (more here[1]):
return $(arg) ? It's there : (alert('Element Does not exist') ||
It's not there);
or, demonstrating manipulation:
return $(arg) ? It's there : (!setTimeout(...) || It's not there);
...since setTimeout returns a non-zero number; !setTimeout is false
and so the return value (for that second operand) is It's not there.
Blech blech.
3. Wrap the two-part bit in an on-the-fly function:
return $(arg) ? true : (function(){ alert('Element Does not exist');
return false;})());
Blech blech cough.
4. Use eval (!):
return $(arg) ? true : eval(alert('Element Does not exist'); return
false;);
Blech blech cough retch.
I bet there are others.
So: *Possible*, but if/else is just a way better way to go. ;-)

[Proto-Scripty] Escaping Input
I have a form, I've been doing this in javascript:
entry = $('busCalForm').serialize(true);
entry = JSON.stringify(entry);
new Ajax.Request(modules/buscal/processes/saveBooking.php, {
parameters: year= + year + recnum= + busmstr_id + json= +
entry,
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});
But i have a user that has typed a # in one of the fields, and the
script dies. How can I effectively escape an entire form, without
having to get the value and escape them individually? Is there a
command I'm missing?

[Proto-Scripty] Re: Escaping Input
Hi,
You're sending an unencoded string (which happens to be in JSON
format) as part of your parameters string, which is meant to be URL-
encoded data. A # sign is the least of your problems. ;-) You'll
want to encode that with JavaScript's encodeURIComponent function[1].
Somewhat OT, but as of 1.6 (at least), the preferred way to provide
options to Ajax.Request is as an object. If you give it a string,
that string will be converted to an object, and then later converted
back into a string. Yes, really. :-) Also, String has a toJSON
function you can use instead of JSON.stringify (not that it matters).
So:
entry = encodeURIComponent($('busCalForm').serialize(true).toJSON());
new Ajax.Request(
modules/buscal/processes/saveBooking.php, {
parameters: {
year: year,
recnum: busmstr_id,
json: entry
},
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});
How can I effectively escape an entire form, without
having to get the value and escape them individually? Is there a
command I'm missing?
That's not quite what your code is doing; you're sending the form
fields as a JSON-encoded string in a parameter called json. If you
just want to send the form fields, and you don't need them to arrive
at the other end as a JSON string, there's a *much* shorter way:
Form#request[2]. Assuming that your form element has the
saveBooking.php as its action attribute:
$('busCalForm').request({
parameters: {
year: year,
recnum: busmstr_id
},
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});
The form fields will no longer be JSON-ified (but will be properly URL-
encoded), they'll arrive as individual parameters on the request. If
the form field doesn't have saveBooking.php as its action and you
can't change that, the Ajax.Request can still be simplified:
params = $('busCalForm').serialize(true);
params.year = year;
params.recnum = busmstr_id;
new Ajax.Request(
modules/buscal/processes/saveBooking.php, {
parameters: params,
onSuccess: busCal.gotEntry.bind(this),
onFailure: busCal.gotFailure.bind(this)
});

Sorry, I got my wires crossed half-way through the first one of
those. You can't use String#toJSON, it's not a string! Doh.
Correcting my first example:
entry = encodeURIComponent(Object.toJSON($('busCalForm').serialize
(true)));
new Ajax.Request(

I'm a occasional user of Prototype and Scriptaculous and pretty happy with these tools. However, I'm facing an issue for which I can find any answer around: I created some pages that work pretty well on modern browsers such as FF 3 or 3.5 and Safari 3 or 4, but I'm asked to make them run on some special Internet devices that run only Mozilla Firefox 1.7 with Javascript 1.5 So my question is : what are the requirements of Prototype 1.6 and Scriptaculous 1.8, will my pages run well on such an old browser. If not, is there an older version of Prototype and/or Scriptaculous that will answer my problem.

[Proto-Scripty] Re: $F() cannot get radio button values?
I suspect you probably want to get the radio *group* by name, and then
see which (if any) of its members is currently checked.
$$('input[name=yourRadioGroup]:checked').first() will get the
element or false. To explicitly get the value, try this:
var myValue = ($$(input[name=yourRadioGroup]:checked).first()) ?
$$(input[name=yourRadioGroup]:checked).first().getValue() : '';

[Proto-Scripty] Re: how sum value from input?
Thanks for the advice.
2009/7/29 T.J. Crowder t...@crowdersoftware.com
Hi,
That version seems okay, except it parses the number twice (first for
isNaN, then again in parseFloat). There's also no need to check for a
blank string, '' can't be converted to a number and so parsing it will
result in NaN. Also, parseFloat defaults to base 10, so no need for
that param (but by all means include it if you think it makes the code
clearer).
var i;
var suma = 0;
var valor;
for (i = 1; i = 24; i++) {
valor = parseFloat($F('quincena_'+ i).strip());
if (!isNaN(valor)) {
suma += valor;
}
}
Note that parseFloat will stop at the first invalid character, so this
doesn't do much in the way of validation. For instance, if the field
contains 15x5, parseFloat will return 15, not NaN. If you need real
validation, you'll probably want RegExps to test for valid patterns.
A web search should do it, if you need to take it that far.
FWIW,

[Proto-Scripty] Re: Using a prototype function in dynamic content.
Sorry, but it's still not working for me.
I have my main page as it initially loads with this in the HEAD
script language=javascript
type=text/javascript
var ipeManager = {
editors: {},
addOrReplaceEditor: function(id, url, size, paramstr){
var eds;
eds = this.editors;
if (eds[id]) {
eds[id].dispose();
delete eds[id]; // Or: eds[id] = undefined;
}
eds[id] = new Ajax.InPlaceEditor(id,url,{size: size,callback:
function(form, value) {return paramstr + escape(value);}});
}
};
/script
Then, in the body of the document is the keyword list:
div id=kwdisp0101A keyword/div
...a bunch of other stuff...
script
ipeManager.addOrReplaceEditor('kwdisp0101','./addkw.php',
17,'oldwd=A%20keywordidx=subject-idmyparam=');
/script
div id=kwdisp0102Another keyword/div
...a bunch of other stuff...
script
ipeManager.addOrReplaceEditor('kwdisp0102','./addkw.php',
17,'oldwd=A%20keywordidx=subject-idmyparam=');
/script
div id=kwdisp0103Yet another keyword/div
...a bunch of other stuff...
script
ipeManager.addOrReplaceEditor('kwdisp0103','./addkw.php',
17,'oldwd=Yet%20another%20keywordidx=subject-idmyparam=');
/script
The content called in by ajax is basically a copy of the keyword list,
and has exactly the same structure and IDs as the list above.
On loading the initial page it works fine, but when the ajax content
has replaced the original list, it no longer works. No Firebug errors,
no nothing.
Did I miss something out?

[Proto-Scripty] What object is it exactly that's passed to the Ajax.Request onSuccess callback?
I've briefly surveyed the documentation, and I really can't figure out exactly what object is passed to the onSuccess callback of the Ajax.Request() method. I've read one statement that says it's the XMLHttpRequest object, so they called the parameter request, which seems very odd for an Ajax callback. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Prototype script.aculo.us group.

Hi, Yes, those docs are messed up (out of date, I think, and will be fixed by the new documentation stuff in 1.6.1). It's an Ajax.Response[1].

[Proto-Scripty] Re: ternary operators
Hi,
I thought that too, but tried it and it didn't work, so I figured I
had to be misremembering. Turns out I just messed up my test. :-)

Hi Alex,
However it cannot be achieved so it must be done usung if/else..
Well, this is JavaScript, there's almost always a way. I can think of
four off the top of my head that keep it in a single expression -- but
all of them are much worse (most of them much, much, much worse) than
using an if/else. ;-) The four are:
1. Massage the return value of the first thing you want to do to force
it to be the return value you want. Actually, in your specific case,
you don't have to anything:
return $(arg) ? true : alert('Element Does not exist');
alert has no return value, hence your function returns either true or
undefined, which is good enough for anything branching on its return
value (undefined is falsey, after all). If you really want a false,
use !! to force it.
Blech.
2. If you wanted to return something other than false, and if the
first part has an invariant result, you could manipulate that return
value to be falsey and use the OR operator, which is much more
powerful in JavaScript than in most languages (more here[1]):
return $(arg) ? It's there : (alert('Element Does not exist') ||
It's not there);
or, demonstrating manipulation:
return $(arg) ? It's there : (!setTimeout(...) || It's not there);
...since setTimeout returns a non-zero number; !setTimeout is false
and so the return value (for that second operand) is It's not there.
Blech blech.
3. Wrap the two-part bit in an on-the-fly function:
return $(arg) ? true : (function(){ alert('Element Does not exist');
return false;})());
Blech blech cough.
4. Use eval (!):
return $(arg) ? true : eval(alert('Element Does not exist'); return
false;);
Blech blech cough retch.
I bet there are others.
You can use comma operator (which evaluates all of its expressions
left to right and evaluates itself to the last expression):
return $(arg) ? true : alert('...'), false;
