 5 | 
 6 | 
 7 | Allows you to call JSON via an Ajax call with a jsonp fallback.
 8 | 
 9 | ```javascript
10 | var geojsonLayer = new L.GeoJSON.AJAX("geojson.json");
11 | ```
12 | for jsonp add the option "dataType" and set it to "jsonp"
13 | ``` javascript
14 | var geojsonLayer = L.geoJson.ajax("http:webhost.fake/geojson.jsonp",{dataType:"jsonp"});
15 | ```
16 | Note that data starts to download when the layer is created NOT when it’s added to the map in order to get a head start.
17 | 
18 | You may pass either a url string or an array of url strings if you want to download multiple things (handy
19 | if your downloading data from an ESRI based thing which will have separate line, point, and poly features).
20 | 
21 | As you see you can also use lower case methods without creating new objects
22 | 
23 | For weirder jsonp you can set "callbackParam" for if you need to change the name of the callback parameter to something besides "callback", e.g. [Mapquest Nominative Open](http://open.mapquestapi.com/nominatim/) uses "json_callback" instead of "callback".
24 | 
25 | If you want to be able to load stuff from the file system (with appropriate custom flags set) set local to true.
26 | 
27 | If you want to set headers to the XMLHttpRequest set the 'headers' option equal to an object.
28 | 
29 | Gives off three events `data:loading`, `data:progress` and `data:loaded`.
30 | 
31 | - `data:loading` fires before we start downloading things, note if the constructor is given a url it won't wait to be added to the map
32 | to start downloading the data, but it does do an async wait so you have time to add a listener to it (and so [leaflet.spin](https://github.com/makinacorpus/Leaflet.Spin) will work with it).
33 | - `data:progress` is called each time a file is downloaded and passes the downloaded geojson as event data.
34 | - `data:loaded` is called when all files have downloaded, this is mainly different from `data:progress` when you are downloading multiple things.
35 | 
36 | You can also add a middleware function which is called after you download the data but before you add it to leaflet:
37 | 
38 | ```javascript
39 | var geojsonLayer = L.geoJson.ajax("route/to/esri.json",{
40 |     	middleware:function(data){
41 |         	return esri2geoOrSomething(json);
42 |     	}
43 |     });
44 | ```
45 | 
46 | addUrl does not clear the current layers but adds to the current one,  e.g.:
47 | 
48 | ```javascript
49 | var geojsonLayer = L.geoJson.ajax("data.json");
50 | geojsonLayer.addUrl("data2.json");//we now have 2 layers
51 | geojsonLayer.refresh();//redownload the most recent layer
52 | geojsonLayer.refresh("new1.json");//add a new layer replacing whatever is there
53 | ```
54 | 
55 | last but now least we can refilter layers without re adding them
56 | 
57 | ```javascript
58 | var geojsonLayer = L.geoJson.ajax("data.json");
59 | geojsonLayer.refilter(function(feature){
60 |     return feature.properties.key === values;
61 | });
62 | ```
63 | 
64 | Behind the scenes are two new classes L.Util.ajax = function (url) for same origin requests and L.Util.jsonp = function (url,options) cross origin ones. Both return promises, which have an additional abort method that will abort the ajax request.
65 | 
66 | ```js
67 | L.Util.ajax("url/same/origin.xml").then(function(data){
68 | 	doStuff(data);
69 | });
70 | //or
71 | L.Util.jsonp("http://www.dif.ori/gin").then(function(data){
72 | 	doStuff(data);
73 | });
74 | ```
75 | 
76 | In related news `L.Util.Promise` is now a constructor for a promise, it takes one argument, a resolver function.
77 | 
78 | Some of the jsonp code inspired by/taken from [this interesting looking plugin](https://github.com/stefanocudini/leaflet-search) that I have failed to make heads nor tails of (the plugin, not the jsonp code)
