using jsonformatter , validator site checking code.

since mentioned

i totally novice json

i explain completely.

there little bit of syntax errors in way doing this. doing loop inside javascript object break. if intention alert models of make, here how it..

initially have this

var data = {             cars:{                   "honda":                    [                     {"model":"figo" },                     {"model":"city"}                    ],                   "audi":                    [                     {"model":"a6"},                     {"model":"a8"}                    ]                  }            } 

you have variable called data object ({} refers object) , object has property called cars , property holds object({} refers object). object has 2 properties honda , audi. each of properties of type array ([] refers array). , each array further contains list of objects.

so once clear above point. let manipulate object have.

do forloop properties of cars object , when have hold of each property lets loop array , extract model property value.

for (var make in data.cars) {   (var = 0; < data.cars[make].length; i++) {      var model = data.cars[make][i].model;          alert(make + ', ' + model);   } } 

also dont confused javascript object , json....

in above example variable data javascript object , when json.strinfigy(data) converting javascript object string format , string format called json...

a demo fiddle understand better.
