Use String as object in javascript?

Question

Here I am dynamically getting a string like this:

  var datN="{y:12 ,marker: {symbol: 'url(http://abc.com//1446/t_23718.gif)'}},72.72727,83.333336";

I want to use it in HighChart api as graph data but this is not working. I have tried and got this that if the code was like this it would work:

  var datN=[{y:12 ,marker: {symbol: 'url(http://abc.com//1446/t_23718.gif)'}},72.72727,83.333336];

so how can I convert the first variable to work like the second one? I am new to javascript please help?

UPDATE

All I want is to convert the first string to object like second one (Second one is working correctly) . I have already tries JSON.parse and eval but they didnt work. So please help?

@Bergi Not an exact duplicate, that string needs some working before being parsed. — MaxArt, Jun 10 '13 at 12:51
I am getting that from a java method which I am using as data for highchart api — Navdroid, Jun 10 '13 at 12:54
@MaxArt: Well yeah, that's why we were asking where he got it from so we can tell him how make that valid JSON :-) — Bergi, Jun 10 '13 at 12:54
@NavdeepSinghBedi: Then you should make that java method output [proper JSON](http://json.org/). Can you show us its code? — Bergi, Jun 10 '13 at 12:58
Why you cannot encode array to JSON and return correct JSON object? — Sebastian Bochan, Jun 10 '13 at 15:08
I have corrected my JSON using http://jsonlint.com/ easily and now it is running I am using the jquery parsing method. — Navdroid, Jun 11 '13 at 06:45

var datArr = JSON.parse("[" + datN + "]");

This may not work across browsers because JSON.parse is not supported by all browsers. I think you could use jquery

var datArr = $.parseJSON("[" + datN + "]");

If it still does not work, you may try

var datArr = eval("[" + datN + "]");

Although this solution is not recommended.

Eval is acceptable as long as the string is sanitized. jQuery has a regex for that. – Šime Vidas Jun 10 '13 at 13:22
@Quentin: an array is still a valid json object. That's not correct?? If you look carefully, this is an array with 3 items. Am I missing something? – Khanh TO Jun 10 '13 at 13:30

JSON requires property names to be strings (not identifiers) and for strings to be delimited with `"` not `'`. – Quentin Jun 10 '13 at 13:31
@Quentin True. Well, eval then, but string has to be sanitized beforehand. – Šime Vidas Jun 10 '13 at 13:33
@Quentin: well, so in this case, only the eval works and it is the simplest solution – Khanh TO Jun 10 '13 at 13:38
