Search and Geolocation
Search
var xhr = new XMLHttpRequest();xhr.open(
‘GET’, 'http://nominatim.openstreetmap.org/?q=' +
query + '&format=json', true);
xhr.send();
new google.maps.places.SearchBox
navigator.geolocation.getCurrentPosition(successCallback, errorCallback, positionOptions
)
Geolocation
http://www.w3.org/TR/geolocation-API/
PositionOptions.enableHighAccuracyPositionOptions.timeoutPositionOptions.maximumAge
Geolocation
function successCallback(position) {
var latitude = position.coords.latitude;
var longitude = position.coords.longitude;
// ...
}

Flow
DOM
Nested View<!– In body of index.html --><div ng-controller="MapController">
<div ng-view></div><div class="maps">
<div id="openstreetmap” ng-class="mapfs.OpenStreetMap_class"></div><div id="googlemap” ng-class="mapfs.GoogleMap_class"></div><div id="hybridmap” ng-class="mapfs.HybridMap_class"></div>
</div></div>
<!– In map.html --><div class="actionBox">
<div class="tabs"><ul><li><a ng-class="mapfs.OpenStreetMap_class"href="#/showOpenStreetMap">OpenStreetMap</a>
</li></ul></div>…
</div>
var app = angular.module("geoapp", ['ngRoute']);
app.config(function ($routeProvider) { $routeProvider .when('/showOpenStreetMap', { templateUrl: "views/map.html", controller: "OpenStreetMapController"} ) ... .otherwise({redirectTo: '/showOpenStreetMap'}) ;});
Route Definition
Controllers
Nested Controllers// Parent Controller.controller('MapController’, function($scope, OpenStreetMap, …){
$scope.mapfs = { OpenStreetMap_class = “” };$scope.showMap = function (mapName) {
if ( mapName === "openstreetmap" ) {$scope.mapfs.OpenStreetMap_class = "active";
}};OpenStreetMap.initMap(“openstreetmap”);… ;
});
// Child Controller.controller(‘OpenStreetMapController’, function ($scope) {
$scope.showMap("openstreetmap");// $scope.mapfs.OpenStreetMap_class is now “active”
});
Providers
BaseGoogleMap.factory('BaseGoogleMap', function (…) {
var MapObject = function () { … };MapObject.prototype = {
initMap: function (mapId) { … };initSearchBox: function (inputId) { … };
};return MapObject;
});
.factory(‘GoogleMap’, function (BaseGoogleMap) {return new BaseGoogleMap();
});
.factory(‘HybridMap’, function (BaseGoogleMap) {var gmap = new BaseGoogleMap();gmap.initMap = function (mapId) { … };return gmap;
});
AngularJS Promise.service('OpenStreetMap', function ($http, $q) {
this.search = function (query) {var url = “http://…” + query, d = $q.defer();
$http.get(url,function (response) {
// Update map with data from responsed.resolve(response);
},function (error) { d.reject(error); }
);
return d.promise;};
});
// Use Promise in ControllerOpenStreetMap.search(“Via del Corso”).then(function (data) {
// data is the same response object passed by $d.resolve});
