javascript - Search object of objects for array value match -

given array parameter ary ["value", "value2"]

i want loop through object of objects find match both array values. i've tried such:

function findmatch (ary) {    storagearray = [];   mykeys = [];   myvalues = [];    (var = 0; < ary.length; i++) {     (obj in object) {       (key in object[obj]) {         if (ary[i] in object[obj]) {            mykeys.push(key);            myvalues.push(object[obj][ary[i]]);         }       }     }    storagearray .push(mykeys, myvalues);    return storagearray; }  var object = {     "subobject" :     {         'key'   : 'value',         'key2'  : 'value2',         'key3'  : 'value3'           },     "subobject2" :      {         'key4'  : 'value4'      }, } 

goal: able return k : v pair each match of value in ary

meaning... since ary has value , value2... want return match object of key : value , key2 : value2.

so far a) isn't working , b) doesn't seem efficient way (3 loops...)

it similar way did, , works.

function findmatch(array, object) {     var result = [];     (var sub in object) {         var subobj = object[sub];         (var key in subobj) {             (var = 0; < array.length; i++) {                 if (subobj[key] === array[i]) {                     result.push({                         k: key,                         v: subobj[key]                     });                 }             }         }     }     return result; }  var result = findmatch(['value', 'value2'], object); (var = 0; < result.length; i++) {     console.log(result[i].k + " : " + result[i].v); } 

here way using lookup object:

function findmatch(array, object) {     var result = [];     var lookup = {};     (var sub in object) {         var subobj = object[sub];         (var key in subobj) {             var value = subobj[key];             if (!lookup[value]) {                 lookup[value] = [];             }             lookup[value].push(key);         }     }     (var = 0; < array.length; i++) {         var val = array[i];         var foundarr = lookup[val];         if (foundarr) {             (var j = 0; j < foundarr.length; j++) {                 result.push({                     k: foundarr[j],                     v: val                 });             }         }     }     return result; }  var result = findmatch(['value', 'value2'], object); (var = 0; < result.length; i++) {     console.log(result[i].k + " : " + result[i].v); }
