I try to load and add a local json file as var for a futur use in my script. I think that the data aren't load when I try to populate my var with the json data but fail to find the solution!

Here is my json file (it's a geojson file but may work as a json) : 

{
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",

                    ]
                ]
            }
        }
    ]
}

And my script 

jQuery.getJSON("/datas/testze.json", function(data) {
    var geojson = data;
});  
console.log(geojson);

I also try 

jQuery.getJSON("/datas/testze.json?jsoncallback=?", function(data) {
    var geojson = data;
});  
console.log(geojson);

In the console the json is load so I guest it's a sync/async problem...

  • It's an async issue...you need to use a callback - or do your logic inside the callback from the `getJSON`. – tymeJV Dec 16 '14 at 15:55
  • You've placed the `console.log` outside the callback, so you're trying to log the values before the data is available, see the duplicate post for a thourough explanation on how it works. – adeneo Dec 16 '14 at 15:56
  • Thanks for your comment. I finally find the solution with the success callback like this jQuery.getJSON("/datas/testze.json", function(data) { }) .success(function(data) { var geojson = data; console.log(geojson); }); – henri_1310 Dec 16 '14 at 16:04
