jQuery.ParseJSON returns a string

Question

I'm getting a string which represents a JSON Object (it's a valid JSON string according to JSONLint).

When I call :

console.log(JSON.parse(datasource_graphe_un));

It returns a string, confirmed by :

console.log(typeof jQuery.parseJSON(datasource_graphe_un));

returning string.

Here's an example of the string I try to parse :

[ {"id":195197,"val":9800,"date":"2009/05/11","ax":1242023901,"number":8,"valval":9200} , ... ]

Why can't I parse it ? And why jQuery.parseJSON returns a string ?

Thank's

If that example is the actual return value, you have an array, not JSON. What is JSON.parse actually returning? — Evan Davis

Alright it works... I don't know why but when I try : JSON.parse(JSON.parse(datasource_graphe_un); it returns the correct object (and yes it is twice). Don't know why. — Nontenda

Yep, probably twice encoding (e.g. you use JSON.stringify() and then encodeURIcomponent()).

Using Chrome's Console, this line works fine for me. You may have to iterate through your array if you are trying to parse several results being stored in the variable datasource_graphe_un.

  var k = $.parseJSON('{"id":195197,"val":9800,"date":"2009/05/11","ax":1242023901,"number":8,"valval":9200}');
