[Proto-Scripty] Re: Revert sortable on return value true? Possible?
I am a bit desperate now. I have tried to work this over and over to
the point where I think I have to give up.
I tried 2 different revert declarations:
1. revert:changeClass
Sortable.create('blank_1',{tag:'span',dropOnEmpty: true,
constraint:true, containment:sections,
only:'lineitem',revert:changeClass});
2. revert:true (so it should always execute - I would think)
Sortable.create('blank_1',{tag:'span',dropOnEmpty: true,
constraint:true, containment:sections, only:'lineitem',revert:true});
Also to make sure that this isn't my functions mistake, I set the
return statement of my changeClass function to true. Meaning that
revert will be set to true and should be executed every single time
the object is dragged.
Here is the very simplified function
function changeClass(el){ return true;}
Leaves me to think that the patch does not work.
I tried again firebug debugging:
Set breakpoints for the patches
revert seems never to be set?
Can anyone help me??

[Proto-Scripty] Re: Revert sortable on return value true? Possible?
I just figured out that if I remove the event 'Update:+function call'
changeClass is never executed during 'revert:changeClass'. I planted
an alert statetement right before the function return statement to see
what value is being returned and it doesn't execute if 'Update' is
removed.
So is it the revert event that is not working?
Sortable.create('blank_1',{tag:'span',dropOnEmpty: true,
constraint:true, containment:sections, only:'lineitem',
revert:changeClass});
doesn't call changeClass function/ nothing is returned
Sortable.create('blank_1',{tag:'span',dropOnEmpty: true,
constraint:true, containment:sections, only:'lineitem',
revert:changeClass, onUpdate:function(el){changeClass(el)}});
calles changeClass function/returns false or true.

They are two, and this is just a place where Lint and Prototype
disagree. This could be written as
if((match = source.match(pattern))) { ...
and Lint would say "Sure! That's just fine! " because that's like
saying if (true){ But Prototype house style is about less typing
(in the keyboard sense of the word) and this assignment-which-returns-
either-false-or-something-truthy will actually **work** in JavaScript.

Hi Alex,
Thanks for being so patient. I deleted the previous message because I
saw your link to the patch after I submitted it. Wow, this is just a
mistery to me, but I added the patch, added revert to the sortable
decleration, checked the return value which is true for what I am
checking and still it doesn't work.
I get a lot of warnings in firebug for prototyp.js, effects.js, and
dragdrop.js.
I haven't invastigated, but I don't think it has anything directly to
do with the patch. Does the patch only work with a certain version of
the files?
Sortable.create('blank_1',{tag:'span',dropOnEmpty: true,
constraint:true, containment:sections, only:'lineitem',
onUpdate:function(el){changeClass(el)}, revert:changeClass});
function changeClass(el){
var flag =false;
var sections = document.getElementsByClassName('section');
sections.each(function(section) {
var sectionID = el.id;
var sectionall_ID = section.id;
var sequence=(Sortable.sequence(el.id));
});
str_post=str_post.join(",");
if(str_post.match(",")){
flag =true;
}
alert((flag == true)?true:false);
return (flag == true)?true:false;
}

Thanks so much Alex,
I am just not sure about Element.hasClassName(el,n.id). First I tried
to have revert:changeClass follow directly after onUpdate:function(el)
{...}, but the script stopped working. So then I included
revert:changeClass inside the update function and I tried to pass
"this" to revert:changeClass, but that didn't work. If I test for
this.id in changeClass I get an undefined. Are the objects/variables
Element, o, and n predefined?
Thanks,
Nathalie
I will give it a try.

[Proto-Scripty] Re: Revert sortable on return value true? Possible?
Thanks so much Alex,
I am just not sure about Element.hasClassName(el,n.id). First I tried
to have revert:changeClass follow directly after onUpdate:function(el)
{...}, but the script stopped working. So then I included
revert:changeClass inside the update function and I tried to pass
"this" to revert:changeClass, but that didn't work. If I test for
this.id in changeClass I get an undefined. Are the objects/variables
Element, o, and n predefined?
Thanks,
Nathalie
I will give it a try.

[Proto-Scripty] Re: Revert sortable on return value true? Possible?
First a patch is needed http://dev.rubyonrails.org/ticket/7396
That tenery operator wont work in that situation you need to evaluate
the return of the function
onUpdate : function (el) {
// do your code
}
revert : changeClass // function call
And you change class must provide a boolean true or false.
function changeClass(el,o,n) {
return (Element.hasClassName( el, n.id)) ? true : false;
}
This should do the trick for you
