Iterate through JSON

i'm wondering how i could loop through this json data to get the values inside it with jquery? All i've got is undefined. I'm using $.ajax.get() to get the file then i'm trying to loop through it to get data inside it. The JSON looks like this...

The result from the get is a string!

    [
    {
        "category": "anti-social-behaviour", 
        "persistent_id": "", 
        "location_subtype": "STATION", 
        "month": "2012-11", 
        "location": {
            "latitude": "52.6313999", 
            "street": {
                "id": 1447707, 
                "name": "Leicester"
            }, 
            "longitude": "-1.1252999"
        }, 
        "context": "", 
        "id": 18782816, 
        "location_type": "BTP", 
        "outcome_status": {
            "category": "Under investigation", 
            "date": "2012-11"
        }
    }
]

You can simply loop through the items like this:

$.each(obj, function(i, val) {
    alert(val.category);
    alert(val.location.latitude);
    alert(val.location.street.id);
});​

Seems the problem was it of course wasn't an object and thats why i couldnt interate through the json... So i used: var obj = jQuery.parseJSON();

and everything works perfectly!

You need to be sure that you have a json object and not a string. After:

for(var i in JSONObject){ // code goes here }

Remember that you can also call the elements in the object using it direct key value.

Exp. ObjName.keyname

Lets say you're getting through ajax call and youre json returned is on some var data, you can parse using $.each

$.each(data, function(i, obj) {
  //use obj.id and obj.name here, for example:
  alert(obj.name);
});
