javascript - JSON Array rearrange/or filter by value of subvalue -

i'm bit stuck problem getting information out of json array. know how retrieve information , parse them. isn't issue. information facebook use jquery, did it's job fine fare.

basically, need restructure json output of following link: https://graph.facebook.com/284521968232566/photos

under tags, you'll see several items. need rearrange whole thing sorted tag. means:

pauke    { [name, source, link], [name, source, link] } trompete { [name, source, link], [name, source, link] } 

obviously, can see, top-level item has 1 item, there more pictures it'll grow.

this might not right form of array, i'm open approaches.

thank you

ok, iterate on data, , on data[i].tags.data, building result array, somthing like:

var json = {} ; // json data - needs pre-populated var result = [] ; // result array var tag ; // temporary variable each tag in turn.  for(var i=0;i<json.data.length;i++) {     if(    typeof json.data[i].tags != 'undefined'         && typeof json.data[i].tags.data != 'undefined'     ) {         for(var j=0;j<json.data[i].tags.data.length;j++) {             tag = json.data[i].tags.data[j] ;             if(typeof(tag.name != 'undefined') {                 if(typeof result[tag.name] == 'undefined') result[tag.name] = [] ;                 result[tag.name][result[tag.name].length] = {                     'name'    : tag.name,                     'source'  : json.data[i].source,                     'link'    : json.data[i].link                 } ;             }         }     } } 

this produces array (of tags), each of array (of images), 1 object containing information each image tag name.
