javascript - Accessing array elment in JSON object is undefined -

i relatively new javascript , new json , got job of changing internal website meets our new company needs. trying access json object array in it. works pretty of objects, except array. everytime seek access elements in array undefined or nan.

when alert(json.stringify(object.data.average[0])); next output

[{"test_count2":"360","succeeded":"185"}]

so know objects trying access there, when alert(json.stringify(object.data.average[0].succeeded)) or

alert(json.stringify(object.data.average[0]['succeeded']))

i undefined

am doing exclusively wrong here? sad, newby, please patient me ;)

thanks in advance!

since it's yet array have this

object.data.average[0][0]['succeeded'];

javascript arrays json undefined
