javascript - json web service Get value from dynamic parameter's name -


please have output json web service:

      {"format":"json",        "success":true,        "errors":[],        "result":        {"**206**":          {"player_name":"stagiaire",            "m":{                 "6480":{"score":0,"answer":"cdgvbdbgd","category_name":"cdgvbdbgd"},                 "6481":{"score":0,"answer":"cdgvbdbgd","category_name":"cdgvbdbgd"},                 "6482":{"score":0,"answer":"cdgvbdbgd","category_name":"cdgvbdbgd"},                 "6483":{"score":0,"answer":"cdgvbdbgd","category_name":"cdgvbdbgd"},                },            "o":{                  ..... },       }      }     }

what want extract value (which 206 can number). asking achieve goal. appreciated.

in case resulting object contains single property number name, i.e.

result = {     206 : {         ...     }     // no other properties here }

then can use like:

var num = object.keys(result).shift();  // "206"

check browser compatibility object.keys() method @ mdn , use shim if needed.
