 var androidVersionName = data.rowsets['androidVersionName'].row;
 console.log(androidVersionName);

and i get this error : Cannot read property 'androidVersionName' of undefined how can i parse data from this jsonObject?

Your JSON object isn't actually valid JSON, if it is supposed to be object and not string. — Michal Brašna

A valid JSON based on your object:

{
    "androidVersionName":"2.3.3",
    "androidVersionId":10,
    "androidId":"fa0bef4b5a48eacb",
    "mobileModel":"sdk",
    "mobileManufacturer":"unknown",
    "mobileId":"GRI34",
    "mobileProduct":"sdk",
    "applicationName":"com.example.socketclient",
    "applicationVersionName":1.0,
    "applicationVersionCode":1,
    "applicationState":"INACTIVE",
    "screenWidth":480,
    "screenHeight":480,
    "screenDensity":240, 
    "screenDensityName":"hdpi",
    "atdPackages":"com.atd.panberes(1)"
}

i have changed my object to exactly what you said! now how can i parse data from it?

Aurélien Thieriot Over a year ago

JSON.parse(data); should do it. If you want to be sure that everything is ok, you can use one of those online parser: json.parser.online.fr

Note also that you can't access a JSON property with "rowset". In your example, it will be "json.androidVersionName".

look at my code and output. code : console.log(data); var json = JSON.parse(data); console.log(json.toString()); var androidVersionName = data.androidVersionName; console.log(androidVersionName);

the object you have to use after the parsing is "json". Not "data". Therefore, the correct way to get AndroidVersionId is: var androidVersionName = json.androidVersionName;

You can't parse it to object. But you can transform it to JS object.

var data = "[androidVersionName=2.3.3, androidVersionId=10, androidId=fa0bef4b5a48eacb, mobileModel=sdk, mobileManufacturer=unknown, mobileId=GRI34, mobileProduct=sdk, applicationName=com.example.socketclient, applicationVersionName=1.0, applicationVersionCode=1, applicationState=INACTIVE, screenWidth=480, screenHeight=480, screenDensity=240, screenDensityName=hdpi, atdPackages=com.atd.panberes(1)]";
var result = {};
data.replace(/(\w+)=(\w+)/g, function(_, left, right) { result[left] = right; })
console.log(result);
