Question

I have a $.get() statement, which returns this (result from a console.log()):

{"desc":"asdasda","dateD":"2012-08-31","dateE":"2012-09- 01","image":"fasdasdasd","categorie":"3"}

Now when I try, in Javascript, to manipulate the array, everything holds an undefined or null value:

var image = data.image;
desc = data.desc;
dateD = data.dateD;
dateF = data.dateE;
image = data.image;
categorie = data.categorie;

Note: the DateF= data.dateE is not a mistake.

Note2: Those statements are all held within the function (data){} function contained in the $.get().

All those assignments return undefined. What am I doing wrong? I have read and re-read the official jQuery doc, without success.

Make sure you set the dataType of the return to json.

If you don’t do this, the result data may be a string and you will need to use JSON.parse(data) to turn it into a usable object.

For example:

$.get(url, getData, function(data){
    //your fn...
}, 'json');
