JSON Parsing in Angular

Question

I am trying to get a list of ID from a JSON file.

So far, the only way to access the "id" object is by using this:

console.log(photos.photosets.photoset[0].id);

As you might tell, it only gives me the correct ID of the first item.

If I try this, it gives me an "undefined":

console.log(photos.photosets.photoset.id);

there is no question here. and it is also unclear how this relates to angular. — djs

No Angular, just JavaScript.

for (i = 0; i < photos.photosets.length; i++) {
 console.log(photos.photosets.photoset[i].id
}

You will need to iterate array of photoset's and produce new array of ids from it. Array.prototype.map is convenient in this case:

var ids = photos.photosets.photoset.map(function(obj) {
    return obj.id;
});

...so that way, I can use it from my factory into a controller? That's what I'm aiming for, to replace ID's in a url by those from the Json...
