我正在尝试为leaflet-angularjs-directive 测试开发离子应用程序。没有多少演示可供我尝试。
我正在使用：calendee（github）的ionic-leafletjs-map-demo https://github.com/calendee/ionic-leafletjs-map-demo
我正在尝试将 LocationsService 复制到另一个服务：HistoricalMapService。每当我添加了 HistoricalMapService 时，“离子服务”的网页视图都是空白的。当我评论它时，网页正在运行，但没有使用 HistoricalMapService。
这是我在 mapController.js (js/controller/mapController.js) 中的代码
angular.module('starter').controller('MapController',
[ '$scope',
'$cordovaGeolocation',
'$stateParams',
'$ionicModal',
'$ionicPopup',
'LocationsService',
/*'HistoricalMapService',*/
'InstructionsService',
function(
$scope,
$cordovaGeolocation,
$stateParams,
$ionicModal,
$ionicPopup,
LocationsService,
/*HistoricalMapService,*/
InstructionsService
) {
/**
* Once state loaded, get put map on scope.
*/
$scope.$on("$stateChangeSuccess", function() {
$scope.locations = LocationsService.savedLocations;
$scope.newLocation;
if(!InstructionsService.instructions.newLocations.seen) {
var instructionsPopup = $ionicPopup.alert({
title: 'Add Locations',
template: InstructionsService.instructions.newLocations.text
});
instructionsPopup.then(function(res) {
InstructionsService.instructions.newLocations.seen = true;
});
}
$scope.map = {
defaults: {
tileLayer: 'https://api.tiles.mapbox.com/v4/sla.c97ab90d/{z}/{x}/{y}.png?access_token=pk.eyJ1Ijoic2xhIiwiYSI6Ik15dE1uclUifQ.ZmSBZxWOZYCSW3m71abSzQ#17'

};
//$scope.goTo(0);
$scope.locate();
});
var Location = function() {
if ( !(this instanceof Location) ) return new Location();
this.lat = "";
this.lng = "";
this.name = "";
};
$ionicModal.fromTemplateUrl('templates/addLocation.html', {
scope: $scope,
animation: 'slide-in-up'
}).then(function(modal) {
$scope.modal = modal;
});
/**

$scope.$on('leafletDirectiveMap.contextmenu', function(event, locationEvent){
$scope.newLocation = new Location();
$scope.newLocation.lat = locationEvent.leafletEvent.latlng.lat;
$scope.newLocation.lng = locationEvent.leafletEvent.latlng.lng;
$scope.modal.show();
});
$scope.saveLocation = function() {
LocationsService.savedLocations.push($scope.newLocation);
$scope.modal.hide();
$scope.goTo(LocationsService.savedLocations.length - 1);
};
/**
* Center map on specific saved location
* @param locationKey
*/
$scope.goTo = function(locationKey) {
var location = LocationsService.savedLocations[locationKey];
$scope.map.center = {
lat : location.lat,
lng : location.lng,
zoom : 12
};
$scope.map.markers[locationKey] = {
lat:location.lat,
lng:location.lng,
message: location.name,
focus: true,
draggable: false
};
};
$scope.goToMapYear = function(histmap) {
var histmap = HistoricalMapService.locateMapYear[histmap];
console.log("Map Year: " + histmap.name);
console.log("Map Layer: " + histmap.tileLayer);
$scope.map = {
defaults: {
tileLayer: histmap.tileLayer
},
center: {
lat: 1.355,

zoom: 14,
minZoom: 12,

}
};
};
/**

*/
$scope.locate = function(){
$cordovaGeolocation
.getCurrentPosition()
.then(function (position) {
$scope.map.center.lat = position.coords.latitude;
$scope.map.center.lng = position.coords.longitude;
$scope.map.center.zoom = 15;
$scope.map.markers.now = {
lat:position.coords.latitude,
lng:position.coords.longitude,
message: "You Are Here",
focus: true,
draggable: false
};
}, function(err) {
// error
console.log("Location error!");
console.log(err);
});
};
}]);
我的historyMapService（js/services/historicalMapService.js）在这里： http: //pastebin.com/mYsU0Dpk
而我的 menu.html (templates/menu.html) 如下：
<ion-nav-bar class="bar-positive nav-title-slide-ios7">
<ion-nav-back-button class="button-clear"><i class="icon ion-ios7-arrow-back"></i></ion-nav-back-button>
</ion-nav-bar>
<ion-nav-view name="menuContent" animation="slide-left-right"></ion-nav-view>
<header class="bar bar-header bar-stable">
<h1 class="title">Map Year</h1>
</header>
<ion-content class="has-header">
<ion-list>
<!--<ion-item nav-clear menu-close ng-click="goTo(locationKey)" ng-repeat="(locationKey,location) in locations track by location.name">
{{location.name}}
</ion-item>-->
<ion-item nav-clear menu-close ng-click="goToMapYear(histmap)" ng-repeat="(histmap,mapyear) in mapyears track by mapyear.name">
{{mapyear.name}}
</ion-item>
</ion-list>
</ion-content>
如何显示图层的名称，当用户单击它时，它将在 TMS TileLayer 中切换地图？
在此先感谢您的帮助。
