angularjs - javascript - Convert object values from array to string -

i'm facing problems objects, json , etc in js. if 1 can me something, amazing! :)

i have object, can't change, this:

{   "page": [     "post",     "delete"   ],   "news": [     "put"   ] } 

i want convert this:

{   "page": "post, delete",   "news": "put" } 

so want object values (arrays) string, tried tostring(), string(), json.stringify, , other approaches internet, (maybe had not done right) none worked me, i'm kind of new on dealing these type of data, if 1 can me, tks!! :d

edit:

and in case got structure:

{   "page": {     "post": [       "post"     ],     "put": 122   },   "news": {     "put": [       "put"     ]   } } 

how can convert like:

{   "page": "post, put:122",   "news": "put" } 

if want modify initial object - enough use object.keys , array.foreach functions:

var obj = {    "page": [      "post",      "delete"    ],    "news": [      "put"    ]  };    object.keys(obj).foreach(function(k) {    obj[k] = obj[k].join(",");  });    console.log(json.stringify(obj, 0, 4));

additional solution complex case:

var obj = {    "page": {      "post": [        "post"      ],      "put": 122    },    "news": {      "put": [        "put"      ]    }  };    object.keys(obj).foreach(function (k) {    var innerkeys = object.keys(obj[k]), items = [];    innerkeys.foreach(function(key) {      items.push((array.isarray(obj[k][key]))? key : key + ":" + obj[k][key]);    });    obj[k] = items.join(",");  });    console.log(json.stringify(obj, 0, 4));
