AppendFromPath function for MooTools->More->ObjectExtras

[Ciul]

Hi pals.

I've seen myself in many circunstances needing something to append or
set values to an object in a given path got from a dynamic string.
I mean, each time receive a different string from some function and
then need to populate an object with values at the path given by that
string.

I wrote a function that could be added to MooTools->More->ObjectExtras
if MooTools developers think it worths it.

In fact I got kinda inspired from MooTools->More->ObjectExtras-
>getFromPath to write it. Thanks for that :P

Note: Look at the javascript console, it will throw some warnings but
you can see the results anyway.

Judge it by yourself and I'd appreaciate any feedback.

Best regards,
Ciul.

I updated it a little:  http://jsfiddle.net/uqcDR/3/

Hope it still works fine, but that's why Tests/Specs were invented :)

Hi Arian.

WOW you got it reduced by...a ton of lines :P very nice :)

It seems still working the same :)

By the way, I don't return the modified object since the function
modifies it itself. I mean, the object passed is modified by the
function itself.

That might be changed now that I think it... LOL

It returns the modified object, like Object.merge does, which could be useful if you use this function to return values in a function.

var foo = function(){

    var obj = {};

    // blah, do something with the object

    return Object.setToPath(obj, 'a.b.c', 100);

};

Ahhh ok, got it.

If that's the case yes, then it shall be modified by the function as
well as return it :P

Hopefully this will be usefull for other MooTools pals

Nice.

Hi Arian.

I corrected a little error while writing you made,

if (i < (l - 1) && (!source.hasOwnProperty(parts[i]) || !
Type.isObject(source[i]))){
to
if (i < (l - 1) && (!source.hasOwnProperty(parts[i]) || !
Type.isObject(source[parts[i]]))){

you missed the parts[i] while asking for the type of source[ ]
and that's it

I normally use a modified getFromPath that has an option to build the path if it doesn't exist and returns the final object. You can build this setFromPath really simply on top of this.
