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?

@NavdeepSinghBedi: Then you should make that java method output proper JSON. Can you show us its code? — Bergi

Why you cannot encode array to JSON and return correct JSON object? — Sebastian Bochan

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.

@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?

JSON requires property names to be strings (not identifiers) and for strings to be delimited with " not '.

Šime Vidas Over a year ago

@Quentin True. Well, eval then, but string has to be sanitized beforehand.

Khanh TO Over a year ago

@Quentin: well, so in this case, only the eval works and it is the simplest solution
