Processing JSON object lists with Mootools Hash

[focusfriend]

For processing JSON object lists I'm using the new Mootools Hash:

http://docs12b.mootools.net/Native/Hash
http://mootools.net/download/tags/1-2b2 (select only "native: hash")

But there seems to be a conflict with Appcelerator, since the
Hash.each() method not only lists the object list itself, but also all
the Hash methods. Try this:


<app:script>

var persons = new Hash([{firstname:'john',name:'doe'},
{firstname:'mary',name:'may'}]);

persons.each( function(value, key) {
Logger.info(key + " " + value);
});
</app:script>

And you get this:

0 [object Object]

1 [object Object]

eachSlice function (D, C, B) { C = C ? C.bind(B) : Prototype.K; var A
= - D, E = [], F = this.toArray(); while ((A += D) < F.length)
{ E.push(F.slice(A, A + D)); } return E.collect(C, B); }

all function (C, B) { C = C ? C.bind(B) : Prototype.K; var A = true;
this.each(function (E, D) {A = A && !!C(E, D);if (!A) {throw
$break;}}); return A; }

any function (C, B) { C = C ? C.bind(B) : Prototype.K; var A = false;
this.each(function (E, D) {if (A = !!C(E, D)) {throw $break;}});
return A; }

...

Yeah, you gotta love some of the Object prototype collusion inside of Prototype. Prototype attaches a bunch of stuff to the object.prototype so this is the side effect.

You could probably check to make sure it's not a function in your iterator:


  persons.each( function(value, key) {
   if (!Object.isFunction(key)) Logger.info(key + " " + value);
 });

Does Appcelerator have fancy JSON object/hash processing features by
itself?

Yeah, we include the Prototype library by default, and it includes tools for using "hashes"

http://www.prototypejs.org/api/hash

Some of methods have different names, but the functionality looks equivalent. A brief google for "mootools prototype" suggests that they step on each other's toes and can't be used in the same file.

yes - we use prototype internally.

You can do:

Object.toJSON(object)

or

string.evalJSON()

on any string to convert it to json.

Yep, I ditched MooTools and are now back to native Prototype. Do you
walk in sync with the latest Prototype release (1.6.0.2)?

We're currently on 1.6.0.  We do try to keep up with the latest prototypes, depending on compatibility and our release cycle.
