at the `responseJSON` property of the response object (the first

[Proto-Scripty] Passing the content of an array in a form
Hi,
I have a little problem. I want to give the content of an array to a new
page through a form. The javascript code is:
this._view.selectedPicts.setAttribute('value', picts);
I retreive the content using mod_python:
fields = util.FieldStorage(req)
selectedPicts = fields['selectedPicts'].split(',')
All works fine under Firefox and Safari/konqueror, but fails under IE8:
Firefox:
fields={'numAdherent': [Field('numAdherent', '20')], 'numEvenement':
[Field('numEvenement', '2')], 'selectedPicts': [Field('selectedPicts',
'P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg')]}
IE8:
fields={'numAdherent': [Field('numAdherent', '20')], 'numEvenement':
[Field('numEvenement', '2')], 'selectedPicts': [Field('selectedPicts',
'[object]')]}
The strange thing is if I log 'picts' before sending the form, it is
correct, even under IE8!
console.debug(OrderingController._submit(): picts= + picts);
Firefox:
2009-11-0 12:53:55,198::DEBUG::OrderingController._submit():
picts=P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg
IE8:
JOURNAL : 2009-11-0 12:55:10,67::DEBUG::OrderingController._submit():
picts=P4052858.JPG,PB135158.JPG,photo20-08-03_DSC5719net_redimensionner.jpg,_DSC0222.jpg,p1010005.jpg
So, why do I get the wrong string in my form field under IE8? What should I
use instead of just 'picts'?
Thanks,

i may be misunderstanding the problem you're describing, but typically
when you submit an array of values with the same field name, you want
to use [] on the end of the field name. It's possible IE is
submitting the array in its object form, which the server is seeing as
string [object] and sending back untouched. If the fields are in
your HTML, they need an attribute like:
input ... name=picts[] /
or if the data is managed by your script, and passed in the
Ajax.Request as part of the parameters option, you still need to wrap
the name into a string:
{ parameters: { picts[] : picts ... } }
Sorry if that's on the wrong track.
Thanks for the explanation.
I was wondering: a better solution is may be to use json? What do you

Re: [Proto-Scripty] Re: Include scripts
Le mercredi 9 décembre 2009 11:25, T.J. Crowder a écrit : Your best bet for something like that is to have a build process that combines the scripts (and then minifies them), and then include the resulting single script with just one script tag. Reading lots of individual script files will be quite slow, because browsers typically will load only one or two at a time, and it takes very perceptible time to individually retrieve even three or four scripts in addition to the other resources on the page. Latency kills. I see. I don't currently have a good recommendation of a build tool to use for this, but if it's just combining files and then running them through jsmin or something similar, any of the usual suspects (rake, ant, etc.) should be able to manage it. I'm not looking for a minimizer, but only to solve dependencies... I guess it needs to introduce a specific tag in the code, like the Google Closure Compiler does. For example: // @include another_script.js Maybe this as already been discussed here? Did anyone already write such tool? Google's just released their Closure Compiler, which handles doing this (including dependency management, although it's a bit of a pain to configure dependencies at present based on comments in the discussion group) as well as handling removing unused code and various other optimisations. It's still very new: http://code.google.com/closure/compiler Well, dependencies is the only thing I'm looking for :o/ If it does not yet exist, I will try to write my own tool (in python, as I'm familiar with this language).

Oh, yes, my real code is correct...
Do your button instances have a function called `_opacity` (with the
underscore)? I'm not a scripty-head and maybe I shouldn't be posting,
but the effect is called Effect.Opacity, and usually when scripty
mixes effects in as element methods, it's the name of the effect with
an initial lower case letter, so wouldn't that just be `opacity`?
Ok, I see the problem: here, _opacity() is a global function, not a
this._navButtons element method...
I want to use the Effect.Opacity effect; what is the best way to implement
this? Should I bind my _opacity() function to the buttons, using methodize?

First check that scripty hasn't already done that (without the

It does not seem to be the case with the Opacity effect..
If you want to call a global function on each entry in an array,
that's easy:
this._navButtons.each(function(item) {
_opacity(item, ...);
});
The problem is to give additionnal params (for Effect.Oppacity); it does not
seem to be possible with each(). That's why I tried invoke()...
You might consider the Effect.Parallel effect, though, if you're
looking to do effects in parallel:
http://wiki.github.com/madrobby/scriptaculous/effect-parallel
I only need 1 effect on several elements. I also tried Effect.multiple, but
the effect is not synchronized on all objects. Neither with a simple loop,
but the delay is very small in this last case (I can't see it)...

[Proto-Scripty] Problem using invoke()
Hi,
I build an array with some DOM elements, and try to apply effects on them
using invoke(). But it does not work.
Ie may be a problem with function defined as pesudo-methods, but I don't
get any usefull error neither in Firebug, nor in IE debugger.
As I want to use Effect.Opacity(), I wrote a pure function as:
function _opacity(el, args) {
new Effect.Opacity(el, args);
}
then in my class:
this._navButtons = [this._view.prevButton,
this._view.nextButton,
this._view.hideButton);
this._navButtons.invoke(_opacity, {'from': 0,
'to': 1,
'duration':1});
In Firebug, I get:
reference to undefined property this[arguments[0]]
[Break on this error]
without any traceback or code line. In IE, I get:
'undefined' a la valeur null ou n'est pas un objet
('undefined' as null value or is not an object)
at line 713 of prototype.js; it is the call to my method:
return value[method].apply(value, args);
What I did wrong? Is it a problem with this context?
