String to Object

So basically I have this code:

var string = '{name: "bob", height: 4, weight: 145}';

I would like to know if it is possible to convert that string into an object. so that I can use

string.name, string.height, and string.weight

(I am retrieving the string variable from a database so I cannot just remove the quotes and make it an object in the first place)

It seems that your string is malformed. In order to work with JSON.parse or even jQuery.parseJSON methods, your keys must have speech marks (" ) around them, like so:

var str = '{"name": "bob", "height": 4, "weight": 145}';
var obj = JSON.parse(str);

You can test this by adding console.log(obj);​ as the final line. Here is my jsFiddle example.

So try to see if you can pull down the data from the server in the format I have suggested and it can then easily be parsed into a JavaScript object.

I would not use string for a variable name, but:

var obj = eval(string);
alert(obj.name);

or you can use jQuery.parseJSON: api.jquery.com/jQuery.parseJSON.

eval, as suggested by Igor, will certainly work but is vulnerable to attack.

Instead you could use a library to parse it for you. There are options in the following link:

Eval is evil... So what should I use instead?
