I have an object called data. Within this object there is another object (or array, I'm not sure....), called maps. To reach maps I just do data.maps and this works on all browsers except for IE. When I console.log(data); i get this:

{
    "maps": [{
        "Media_Map_Id": "55",
        "Media_Id": "657"
    }]
}

When I console.log(data.maps); it says undefined....

I also got this error, it might have something to do with it eventhough I already fixed it.

Unable to get property 'length' of undefined or null reference

code:

    if(data.maps) {
        dMapsLength = data.maps.length;
    } else {
        dMapsLength = 0;
    }

    for (var i = 0; i < dMapsLength; i++) {
        createVars(data.maps[i], i);
    }

SOLVED (credits to evolutionxbox):

  if (typeof(data) !== 'object') {
       data = JSON.parse(data);
   }

should it not be data[0] – krisph Aug 16 '17 at 07:56
@krisph console.log(data[0]); returns a bracket "{" – Mike Lammers Aug 16 '17 at 07:58
@krisph no `data` is not an array. – evolutionxbox Aug 16 '17 at 07:58
try `data['maps']` – raksa Aug 16 '17 at 07:58
@MikeLammers you have to parse the json first. Use `JSON.parse(data)` – evolutionxbox Aug 16 '17 at 07:59
@raksaeng console.log(data['maps']); returns undefined – Mike Lammers Aug 16 '17 at 07:59
can we see your whole code? – raksa Aug 16 '17 at 08:01
use this before accessing: data = JSON.parse(data); – krisph Aug 16 '17 at 08:02
Open developer tools and put break point on first row of your result to see the data object. Check if data object is json string and use JSON.parse(data). If it json object, so check what the structure of this object to access parameters in right way – freethinker Aug 16 '17 at 08:03
@evolutionxbox Thanks it works now. But why does it work without JSON.parse on normal browsers but not on IE ? – Mike Lammers Aug 16 '17 at 08:03
maybe something wrong with AJAX on IE, when you use it – raksa Aug 16 '17 at 08:07
This could be a duplicate of:
**Can't access object property, even though it exists. Returns undefined** https://stackoverflow.com/a/17547032/4876771 Please check it and mark this accordingly. – Gregg Od Aug 16 '17 at 08:01
