jquery - Add Leaflet GeoJSON layers from GeoServer to an Array using a Javascript loop -

-

i'm trying add geojson layers array using loop, , showing them on map.

my goal have variable this: scenario_json[1] = layer1, scenario_json[2] = layer2, etc...

    myurl = [     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase1&maxfeatures=400&maxfeatures=400&outputformat=json&format_options=callback:getjson",     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase2&maxfeatures=400&outputformat=json&format_options=callback:getjson",     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase3&maxfeatures=400&outputformat=json&format_options=callback:getjson" ];   $.getscript('src/leaflet.js');  for(i=0;i<=myurl.length;i++){      var scenario_json = {};     scenario_json[i] = new l.geojson();      function getjson(data){         console.log(data)         scenario_json[i].adddata(data);      }      $.ajax({         url: myurl[i],         jsonp: false,         datatype: "json",         jsonpcallback: "getjson",         success: getjson     }) };

i getting response in console:

object {readystate: 1} vm3689:10 object {type: "featurecollection", totalfeatures: 386, features: array[386], crs: object} vm3689:11 uncaught typeerror: cannot read property 'adddata' of undefinedgetjson @ vm3689:11c @ jquery.min.js:3p.firewith @ jquery.min.js:3k @ jquery.min.js:5r @ jquery.min.js:5 vm3689:10 object {type: "featurecollection", totalfeatures: 377, features: array[377], crs: object} vm3689:11 uncaught typeerror: cannot read property 'adddata' of undefined

any idea why doesn't work ?

thanks

what's happening scenario_json doesn't exist in context of getjson callback.

i'm unsure why you're using jsonp since it's old workaround making crossdomain requests. don't need since you're working localhost/same domain @ moment. try use plain xhr json instead of jsonp.

remove formatoptions url's:

myurl = [     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase1&maxfeatures=400&maxfeatures=400&outputformat=json",     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase2&maxfeatures=400&outputformat=json",     "http://localhost:8080/geoserver/jonquiere_local/ows?service=wfs&version=1.0.0&request=getfeature&typename=jonquiere_local:buildings_phase3&maxfeatures=400&outputformat=json" ];

switch $.getjson:

for (i = 0; <= myurl.length; i++) {      var scenario_json = {};      $.getjson(myurl[i], function (data) {         scenario_json[i] = new l.geojson(data);     }).done(function () {         console.log('$.getjson done!');     }).fail(function () {         console.log('$.getjson fail!');     }); }

here's working example on plunker: http://plnkr.co/edit/fnf9cdtbccsj3cavvjjy?p=preview

ps. if ever run crossdomain issues can simple solve enabling cors on geoserver.
