AngularJS Ionic Leaflet - Map markers not showing - angularjs

So Ive been trying to get leaflet working in an Ionic app and everything is working fine except my markers. They are not being shown in the default screen nor the locate() function. below is my code
html snippet
<leaflet defaults="map.defaults" center="map.center" markers="map.markers" ng-if="map"></leaflet>
controller
app.controller('MapController',function($scope, $cordovaGeolocation, $stateParams) {
$scope.$on("$stateChangeSuccess", function() {
$scope.map = {
defaults: {
tileLayer: 'http://{s}.tile.osm.org/{z}/{x}/{y}.png',
maxZoom: 18,
zoomControlPosition: 'bottomleft'},
center: {
lat : 20.6219444444,
lng : -105.228333333,
zoom : 15},
markers: {
lat : 20.6219444444,
lng : -105.228333333,
message: "Puerto Vallarta, MX",
focus: true,
draggable: false}
};
});
$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 = 16;
$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);
});
};
});
any ideas?? thanks for looking

SOLVED
I added marker value to a variable and then copied that into the $scope.map
here is the updated working controller
app.controller('MapController',function($scope, $cordovaGeolocation, $stateParams) {
$scope.$on("$stateChangeSuccess", function() {
var mainMarker = {
lat: 20.6219444444,
lng: -105.228333333,
focus: true,
message: "Puerto Vallarta, MX",
draggable: false};
$scope.map = {
defaults: {
tileLayer: 'http://{s}.tile.osm.org/{z}/{x}/{y}.png',
maxZoom: 18,
zoomControlPosition: 'bottomleft'},
center: {
lat : 20.6219444444,
lng : -105.228333333,
zoom : 15},
markers: {
mainMarker: angular.copy(mainMarker)}
};
});
$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 = 16;
$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);
});
};
});

Angular js ngclick doesnt work in infowindow

I created a map with Google maps. At first the infowindow is open when the init function is called. I select a place from the map $scope.kds is working and the contents of the infowindow change. There is a button in the infowindow. When I click the button doesnt work. How can I do?
window.ngApp = angular.module('test', []);
window.ngApp.controller('controllerMap', ['$scope', '$location', '$compile', function ($scope, $location, $compile) {
$scope.init = function () {
$scope.latlng = new google.maps.LatLng($scope.lat, $scope.lng);
$scope.map = new google.maps.Map(document.getElementById('map'), {
center: $scope.latlng,
zoom: $scope.zoom,

maxZoom: 21
});
$scope.marker = new google.maps.Marker({
map: $scope.map,
position: $scope.latlng,
draggable: true,
icon: 'static/img/pin-4ldpi.png'
});
$scope.infowindow = new google.maps.InfoWindow({
content: "",
maxWidth: 175
});
google.maps.event.addListener($scope.map, 'click', function (event) {
$scope.kds ();
});
$scope.kds = function(){
$.ajax({

}
}

Angular leaflet - Showing multiple marker issue

I am using the following code to add markers in leaflet:
.controller('MapController',
[ '$scope',
'$cordovaGeolocation',
'$stateParams',
'$ionicModal',
'$ionicPopup',
'$http',
function(
$scope,
$cordovaGeolocation,
$stateParams,
$ionicModal,
$ionicPopup,
$http
) {
$scope.$on("$stateChangeSuccess", function() {
$scope.map = {
defaults: {
tileLayer: 'http://{s}.tile.osm.org/{z}/{x}/{y}.png',
maxZoom: 18,
zoomControlPosition: 'bottomleft'
},
markers : {},
events: {
map: {
enable: ['context'],
logic: 'emit'
}
}
};
$scope.locate();
});
$scope.locate = function(){
$scope.map.center = {
lat : location.lat,
lng : location.lng,
zoom : 12,
};
var Location = function() {
if ( !(this instanceof Location) ) return new Location();
this.lat = "";
this.lng = "";
this.name = "";
};
$ionicModal.fromTemplateUrl('templates/addLocation.html', {

}).then(function(modal) {
$scope.modal = modal;
});
$scope.map.markers.push=({
lat:35.654,
lng:73.244,
message:'demo 1'
})
$scope.map.markers.push=({
lat:38.654,
lng:73.244,
message:'demo 2'
})
$scope.$on('leafletDirectiveMap.click', function(event, locationEvent){
$scope.newLocation = new Location();
$scope.newLocation.lat = locationEvent.leafletEvent.latlng.lat;
$scope.newLocation.lng = locationEvent.leafletEvent.latlng.lng;
$scope.modal.show();
});
$scope.saveLocation = function(lat, lang) {
//LocationsService.savedLocations.push($scope.newLocation);
//alert(lat + " - " + lang);
var link = 'http://192.168.5.110/server/addLocation.php';
var json1 = {l1 : lat, l2 : lang , l3: sessionStorage.getItem('loggedin_phone')};
$http.post(link, { data: json1 })
.then(function (res){
$scope.response = res.data.result;
if($scope.response.created=="1"){

//no back option
/*

}else{
$scope.title="Failed";
$scope.template="Contact Our Technical Team";
}
var alertPopup = $ionicPopup.alert({
title: $scope.title,
template: $scope.template
});
});
$scope.modal.hide();
};
$cordovaGeolocation
.getCurrentPosition()
.then(function (position) {
$scope.map.center.lat = position.coords.latitude;
$scope.map.center.lng = position.coords.longitude;
$scope.map.center.zoom = 18;
$scope.map.markers.now = {
lat:position.coords.latitude,
lng:position.coords.longitude,
focus: true,
draggable: false,
//message: ''
};
}, function(err) {
// error
console.log("Location error!");
console.log(err);
});
};
}]);
But only the demo2 marker is displaying.
Is there a way to show multiple markers on the leaflet map by using JSON data of latitudes and longitudes loaded from API?
<leaflet defaults="defaults" event-broadcast="events" lf-center="center" markers="markers" layers="layers" id="global-map" width="100%" height="240px"></leaflet>
<leaflet defaults="defaults2" event-broadcast="events2" lf-center="center2" markers="markers2" layers="layers2" id="global-map2" width="100%" height="240px"></leaflet>

Strange way to load the google map

I am using AngularJS + ionic and I am trying to create a google map. I am using the plugin cordova to get the exact position of the user and it works. In addition, the map is loaded only when the person takes a photo, there, is where obtendo such data. So there I have no problem, but the way the map is loaded strange, is clipped and navigation is pesima. I leave you my code and a picture of how the map looks.
<map center="{{latitud}}, {{longitud}}" zoom="15" style="width:100%;height:100%;" data-tap-disabled="true" id="mapa_view">
<marker position="{{latitud}}, {{longitud}}" />
</map>
.controller("CamaraCtrl", function($scope,$rootScope, Camera,$cordovaGeolocation) {
var posOptions = {timeout: 10000, enableHighAccuracy: false};
$cordovaGeolocation
.getCurrentPosition(posOptions)
.then(function (position) {
var latitud_actual = position.coords.latitude
var longitud_actual = position.coords.longitude
$scope.latitud = latitud_actual;
$scope.longitud = longitud_actual;
}, function(err) {
// error
});
$scope.mostrar_form = false;
$scope.getPhoto = function() {
Camera.getPicture().then(function(imageURI) {
console.log(imageURI);
$scope.lastPhoto = imageURI;
$scope.mostrar_form = true;
}, function(err) {
console.err(err);
}, {
quality: 75,
targetWidth: 320,
targetHeight: 320,
saveToPhotoAlbum: false
});
};
$scope.getPhoto();
})

Geo Location - Using Ionic Framework, AngularJS and Google API

We are trying to using this Codepen within our latest Ionic Framework/AngularJS project and can't seem to figure this issue out.
We want to be able to click 'Find Us' and have the Google Map Marker display our current location.
If anyone can see where we're going wrong please let us know.
Thank you.
// Google Map
.controller('MapCtrl', function($scope, $ionicLoading, $compile) {
function initialise() {
var myLatlng = new google.maps.LatLng(53.068165,-4.076803);
var mapOptions = {
zoom: 15,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP,
}
var map = new google.maps.Map(document.getElementById('map'), mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
});
$scope.map = map;
}
google.maps.event.addDomListener(window, 'load', initialise);
$scope.centerOnMe = function() {
if(!$scope.map) {
return;
}
$scope.loading = $ionicLoading.show({
showBackdrop: true
});
navigator.geolocation.getCurrentPosition(function(pos) {
$scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
$scope.loading.hide();
},
function(error) {
alert('Unable to get location: ' + error.message);
});
};
});
Here's a good example of this.
Codepen link
.controller('MarkerRemoveCtrl', function($scope, $ionicLoading) {
$scope.positions = [{
lat: 43.07493,
lng: -89.381388
}];
$scope.$on('mapInitialized', function(event, map) {
$scope.map = map;
});
$scope.centerOnMe= function(){
$ionicLoading.show({
template: 'Loading...'
});
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
$scope.positions.push({lat: pos.k,lng: pos.B});
console.log(pos);
$scope.map.setCenter(pos);
$ionicLoading.hide();
});
};
});
I did use a directive for google maps, just to keep everything in angular-land.
Here is a CodePen of an Ionic app with Google Maps
angular.module('ionic.example', ['ionic'])
.controller('MapCtrl', function($scope, $ionicLoading, $compile) {
function initialize() {
var myLatlng = new google.maps.LatLng(43.07493,-89.381388);
var mapOptions = {
center: myLatlng,
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"),
mapOptions);
//Marker + infowindow + angularjs compiled ng-click
var contentString = "<div><a ng-click='clickTest()'>Click me!</a></div>";
var compiled = $compile(contentString)($scope);
var infowindow = new google.maps.InfoWindow({
content: compiled[0]
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Uluru (Ayers Rock)'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
$scope.map = map;
}
google.maps.event.addDomListener(window, 'load', initialize);
$scope.centerOnMe = function() {
if(!$scope.map) {
return;
}
$scope.loading = $ionicLoading.show({
content: 'Getting current location...',
showBackdrop: false
});
navigator.geolocation.getCurrentPosition(function(pos) {
$scope.map.setCenter(new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude));
$scope.loading.hide();
}, function(error) {
alert('Unable to get location: ' + error.message);
});
};
$scope.clickTest = function() {
alert('Example of infowindow with ng-click')
};
});
when you find the current location of your phone first you find out the latitude and longitude.So First,Add the plugin your project
1.cordova plugin add cordova-plugin-geolocation
2.module.controller('GeoCtrl', function($cordovaGeolocation,$http) {
var posOptions = {timeout: 10000, enableHighAccuracy: false};
$cordovaGeolocation
.getCurrentPosition(posOptions)
.then(function (position) {
var lat = position.coords.latitude //here you get latitude
var long = position.coords.longitude //here you get the longitude
$http.get('http://maps.googleapis.com/maps/api/geocode/json?latlng='+lat+','+long+'&sensor=true').then(function(data){ $rootScope.CurrentLocation=data.data.results[0].formatted_address;//you get the current location here
}, function(err) {
// error
});
}, function(err) {
// error
});

Weird behavior of angular-google-maps in Safari

Im using this project (http://angular-google-maps.org/#!/) to work with AngularJS. My code seems like:
app.js
function ( $scope, markerService ) {
var markerCollection = [];
angular.extend($scope, {
map: {
control: {},
center: {
latitude: 33.5,
longitude: -112
},
zoom: 10,
fit: true,
visible: true,
pan: true,
options: {
navigationControl: true,
scaleControl: true
}
}
});
var setMapMarkers = function (){
var markers = {};
var index = 0;
angular.forEach($scope.services, function (key) {
var service = key.address;
markerCollection.push(service);
var serviceId = service.service.id;
markers[index] = {
"latitude": parseFloat(service.latitude),
"longitude": parseFloat(service.longitude)
};
index++;
});
$scope.markers = markers;
};
setMapMarkers();
}
Im getting this behavior in Safari and its a very weird.

Someone maybe know what can be the problem?
