JSON.parse error in jquery

Question

I am retrieving values from server side code and here is my value ..

["INCOMING",09:09:49,"INETCALL",00:14:09,"ISD",00:05:50,"LOCAL",02:38:02,"STD",01:39:28]

Now as per my need i want to parse it into JSON but on parsing it is giving error..

SyntaxError: JSON.parse: expected ',' or ']' after array element

var dbdata=JSON.parse(data);

and here is my code to get value from server side and parse it into json..

$.ajax({
                type: 'GET',
                url: 'getdataduration',
                async:false,
                dataType: "text",
                success: function(data) {

                    var dbdata=JSON.parse(data);

                    for(var i=0,len=dbdata.length;i<len;i++){
                        $.isNumeric(dbdata[i]) ?  callduration.push(dbdata[i]) :  toc.push(dbdata[i]);
                    }
                }

            });

Please guys help me. Thanks in advance..

The problem is because the value from your server isn't JSON, it's an array. — Rory McCrossan

The response isn't valid. 09:09:49 and other times aren't supported as literals and should be quoted. — Jonathan Lonowski

if you are using php in server side... send response as json with echo json_encode(); . the response you are getting is not JSON... that is an array — bipen

@RoryMcCrossan sir if i put time 00:14:09 as "00:14:09" then will it be parsed — Adi

That's correct. By adding the quotes it becomes a valid JSON format, and can be parsed. — Rory McCrossan

The value from your server isn't JSON fromat, it's array! The JSON format reference:https://developer.mozilla.org/en-US/docs/JSON

I think you should generate the data from your server like this:

[{"INCOMING"："09:09:49","INETCALL"："00:14:09","ISD"："00:05:50","LOCAL"："02:38:02","STD"："01:39:28"}]

I'd remove the outer square brackets, then it's probably what the data is trying to convey.

if single object,remove;object list,remain

The value is not valid JSON nor is it valid JS. Every second elemt is invalid

E.g 09:09:49 is not valid it should (probably) be "09:09:49"

The below is a valid array and can be parsed with JSON.parse

["INCOMING","09:09:49","INETCALL","00:14:09","ISD","00:05:50","LOCAL","02:38:02","STD","01:39:28"]

an easy way to test these kinds of issues is to dump the server reply into the browser development console and see what errors if any that produce

You can test easily the validty of a JSON with this web tool:

http://jsonlint.com/

Parse error on line 2:
...    "INCOMING",    09: 09: 49,    "INE
----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '['

As bipen says, if you use PHP, send your data using json_encode(); and put json as datatype in your $.ajax

Correct JSON Data:

// you should create your json like this
var data = '[{
        "INCOMING" : "09: 09: 49",
        "INETCALL" : "00: 14: 09",
        "ISD" : "00: 05: 50",
        "LOCAL" : "02: 38: 02",
        "STD" : "01: 39: 28"
    }
]';

Correct Ajax use with JSON:

// use 'type: post' and 'dataType: json'. Because, post is safe and 
you are dealing with json data so it must be dataType: json
$.ajax({
    type : 'POST',
    url : 'getdataduration',
    async : false,
    dataType : "JSON",
    success : function (data) {
        var dbdata = JSON.parse(data);
        for (var i = 0, len = dbdata.length; i < len; i++) {
            $.isNumeric(dbdata[i].YOUR_JSON_KEY)
            ? callduration.push(dbdata[i].YOUR_JSON_KEY) 
            : toc.push(dbdata[i].YOUR_JSON_KEY);
        }
    }
});

Conclusion:

You are using '$.isNumeric(dbdata[i])' but, as your json data your 
first value is string. So it's not gonna to work.
