Hi,

i got a ajax json response in my javascript page as below

{"result":"[VSummary [userName=kk, plan=Professional, sDate=null, plate=EVA 5653, groupName=null, vehicleType=null, defaultDriver=null, solrQuery=null, driver=null, firstActiveTime=0, lastActiveTime=0, distance=0.0, maxSpeed=0.0, exceptions=0, trips=0, fuelConsumed=0.0, movHrs=0.0, stopHrs=0.0, idlingHrs=62000.0, engineHrsOn=0.0, engineHrsOff=0.0, workingHrs=0.0]]"}

Here VSummary is a list of object retured from my java application. How can i convert VSummary to list in JAVASCRIPT

JSON.parse is not working here

var a=JSON.parse(response.result); // here response is the json response
SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON data

What I have tried:

JavaScript

var response = JSON.parse('{"result":"[VSummary [userName=kk, plan=Professional, sDate=null, plate=EVA 5653, groupName=null, vehicleType=null, defaultDriver=null, solrQuery=null, driver=null, firstActiveTime=0, lastActiveTime=0, distance=0.0, maxSpeed=0.0, exceptions=0, trips=0, fuelConsumed=0.0, movHrs=0.0, stopHrs=0.0, idlingHrs=62000.0, engineHrsOn=0.0, engineHrsOff=0.0, workingHrs=0.0]]"}');

JavaScript

var a=JSON.parse(response.result);

SyntaxError: JSON.parsed character at line 1 column 2 of the JSON data

JavaScript

var a=response.result["VSummary"]

undefined

response.result is this

[VSummary [userName=kk, plan=Professional, sDate=null, plate=EVA 5653, groupName=null, vehicleType=null, defaultDriver=null, solrQuery=null, driver=null, firstActiveTime=0, lastActiveTime=0, distance=0.0, maxSpeed=0.0, exceptions=0, trips=0, fuelConsumed=0.0, movHrs=0.0, stopHrs=0.0, idlingHrs=62000.0, engineHrsOn=0.0, engineHrsOff=0.0, workingHrs=0.0]]

so that is what you are trying to parse when you execute

var a=JSON.parse(response.result);

however that text is not JSON so you can't use JSON.parse to parse it, you'd need to write your own js code to parse it or update the java code that is sending the response to return you valid json.

This may not be a proper method to parse a JSON data, but the response you are getting is not a valid JSON format, so you shall try this if in case the response will be in the same format on all cases.

var response = JSON.parse('{"result":"[VSummary [userName=kk, plan=Professional, sDate=null, plate=EVA 5653, groupName=null, vehicleType=null, defaultDriver=null, solrQuery=null, driver=null, firstActiveTime=0, lastActiveTime=0, distance=0.0, maxSpeed=0.0, exceptions=0, trips=0, fuelConsumed=0.0, movHrs=0.0, stopHrs=0.0, idlingHrs=62000.0, engineHrsOn=0.0, engineHrsOff=0.0, workingHrs=0.0]]"}');
     var a = response.result;
    a=  a.replace('[', '(').replace(']]', ']');
    a = a.replace('[', ':{').replace(']', '}');
    a = a.replace(/, /g, '","').replace(/=/g, '":"');
    a = a.replace('{', '{"').replace('}', '"}').replace('(', "{") + '}';
    a = a.replace("VSummary", '"VSummary"');
    var obj = JSON.parse(a);
    var userName = obj.VSummary.userName; // KK
    var plan = obj.VSummary.plan;  // Professional
    var plate = obj.VSummary.plate; // EVA 5653
