javascript - Access elements in JSON after ajax request -

i have spent last couple of hours trying figure out this. make ajax request using jquery. response in string format , use

jquery.parsejson(response); 

to convert object. response:

{     "columns": ["n"],     "data": [         [{             "extensions": {},             "labels": "http://localhost:7474/db/data/node/168/labels",             "outgoing_relationships": "http://localhost:7474/db/data/node/168/relationships/out",             "traverse": "http://localhost:7474/db/data/node/168/traverse/{returntype}",             "all_typed_relationships": "http://localhost:7474/db/data/node/168/relationships/all/{-list|&|types}",             "property": "http://localhost:7474/db/data/node/168/properties/{key}",             "self": "http://localhost:7474/db/data/node/168",             "properties": "http://localhost:7474/db/data/node/168/properties",             "outgoing_typed_relationships": "http://localhost:7474/db/data/node/168/relationships/out/{-list|&|types}",             "incoming_relationships": "http://localhost:7474/db/data/node/168/relationships/in",             "create_relationship": "http://localhost:7474/db/data/node/168/relationships",             "paged_traverse": "http://localhost:7474/db/data/node/168/paged/traverse/{returntype}{?pagesize,leasetime}",             "all_relationships": "http://localhost:7474/db/data/node/168/relationships/all",             "incoming_typed_relationships": "http://localhost:7474/db/data/node/168/relationships/in/{-list|&|types}",             "metadata": {                 "id": 168,                 "labels": []             },             "data": {                 "name": "1"             }         }]     ] } 

i try access specific elemets of object nothing back. when try

var test = json.data; 

it works how can access values saved in metadata. try "undefined":

var test = json.data.metadata.id; 

any idea missing?

it array, you've use index

var test = json.data[0][0].metadata.id; 

json.data[0] returns [{...}] , again [{...}][0] returns {...} has metadata object, in turn id property need.
