Geo Location - Using Ionic Framework, AngularJS and Google API - angularjs

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
});
}):

How to get coordinates values while long tap/hold in ionic google maps

I am trying to get coordinates while tap or hold events in ionic from the Google Maps.
While holding I am getting values in browser console not getting in device.
How to clear this issue?. I need to get values while holding/taping in mobile apps using ionic framework [google maps].
Any help would be appreciated.Thanks in advance.
.controller('HomeCtrl', function ($scope, $rootScope, $cordovaGeolocation, $ionicLoading, $ionicGesture) {
$ionicLoading.show({
template: '<ion-spinner icon="bubbles"></ion-spinner><br/>Acquiring location!'
});
var posOptions = {
enableHighAccuracy: true,
timeout: 20000,
maximumAge: 0
};
$cordovaGeolocation.getCurrentPosition(posOptions).then(function (position) {
var lat = position.coords.latitude;
var long = position.coords.longitude;
$rootScope.currentlat = lat;
$rootScope.currentlong = long;
var myLatlng = new google.maps.LatLng(lat, long);
$rootScope.myLatlng = myLatlng;
var mapOptions = {
center: myLatlng,
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
$scope.map = map;
marker = new google.maps.Marker({
position: myLatlng,
map: $scope.map
});
var element = angular.element(document.querySelector('#map'));
$ionicGesture.on('hold', function(e){
$scope.$apply(function() {
alert('hold happens');
google.maps.event.clearListeners(map, 'click');
google.maps.event.addListener(map, 'click', function(event) {
alert(event.latLng);
});
});
}, element);
google.maps.event.addListener(marker, "click", function (event) {
});
$ionicLoading.hide();
}, function (err) {
$ionicLoading.hide();
console.log(err);
});
}
I think your problem is that your using
$ionicGesture.on('hold')
Iconic uses Cordova and Cordova google maps has its own event handler as the "map" is in native view not JavaScript related. You can read up in more detail here.
So once your device is ready
var map = new google.maps.Map(document.getElementById("map"), mapOptions),
longClick = plugin.google.maps.event.MAP_LONG_CLICK;
map.on(longClick, function (latLng) {
var selectedLatLocation = latLng.lat.toString();
var selectedLongLocation = latLng.lng.toString();
alert(selectedLatLocation, selectedLongLocation);
});

Showing google map pinpoints dynamically using angularjs

I am trying to show pin points on google map by matching the location and retreiving list of longitude, latitude saved in the database when user enters location using AngularJS, HTML and Java. Following is my controller code. Please help me achieve my target
app.controller('mapCtrl', function ( $scope, $http) {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(25,80),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
$scope.map = new google.maps.Map(document.getElementById('map'), mapOptions);
$scope.markers = [];
$scope.cities = [];
$scope.lati = [];
$scope.longi = [];
$scope.desc = [];
var infoWindow = new google.maps.InfoWindow();
$http.get('http://localhost:8080/acudraStore/getCity').
success(function( data){
for(i = 0;i <=3;i++){
$scope.cities.push(data.countryList[i].city);
$scope.lati.push(data.countryList[i].latitude);
$scope.longi.push(data.countryList[i].longitude);
$scope.desc.push(data.countryList[i].desc);
}
var createMarker = function (){
console.log($scope.cities[0]);
var marker = new google.maps.Marker({
map: $scope.map,
position: new google.maps.LatLng($scope.lati[0], $scope.longi[0]),
title: $scope.cities[0]
});
marker.content = '<div class="infoWindowContent">' + $scope.desc[0] + '</div>';
google.maps.event.addListener(marker, 'click', function(){
infoWindow.setContent('<h2>' + marker.title + '</h2>' + marker.content);
infoWindow.open($scope.map, marker);
});
$scope.markers = [];
$scope.markers.push(marker);
$scope.markers = [];
for (i = 0; i < markers.length; i++){
createMarker(markers[i]);
}}
});
$scope.openInfoWindow = function(e, selectedMarker){
e.preventDefault();
google.maps.event.trigger(selectedMarker, 'click');
}
});
The example (similar to the provide in question) demonstrates how to load locations from external resource and display markers with info window:
var app = angular.module('mapApp', []);
app.controller('mapCtrl', function ($scope, $http) {
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-25.5349952, 125.8554386),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
$scope.map = new google.maps.Map(document.getElementById('map'), mapOptions);
$scope.markers = [];
$scope.cities = [];
var infoWindow = new google.maps.InfoWindow();
$http.get('https://gist.githubusercontent.com/vgrem/dd818d266445f1a653c1/raw/e768daf280bab0791c2c27ae0f3d5952490bc2a5/cities.json').
success(function (data) {
$scope.cities = data.countryList;
$scope.cities.forEach(function(city) {
createMarker(city);
});
});
var createMarker = function(city) {
var marker = new google.maps.Marker({
map: $scope.map,
position: new google.maps.LatLng(city.latitude, city.longitude),
title: city.city
});
marker.content = '<div class="infoWindowContent">' + city.desc + '</div>';
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent('<h2>' + marker.title + '</h2>' + marker.content);
infoWindow.open($scope.map, marker);
});
$scope.markers.push(marker);
};
//$scope.openInfoWindow = function (e, selectedMarker) {
// e.preventDefault();
// google.maps.event.trigger(selectedMarker, 'click');
//}
});
#map {
width: 800px;
height: 600px;

Incorrect marker location

I am Using the $http Service in Ionic to dynamically load Google Map Markers, and I use this method:
google.maps.Geocode
To give a lat and lang, but this code is throwing some error.
facebookExample.controller('carteController', function ($scope, $ionicLoading, $location, $cordovaGeolocation, $compile, $http) {
$scope.back = function () {
$location.path("/accueil");
}
$scope.init = function () {

});
var options = {timeout: 10000, enableHighAccuracy: true};
$cordovaGeolocation.getCurrentPosition(options).then(function (position) {
var latLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var mapOptions = {
center: latLng,
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
$scope.map = new google.maps.Map(document.getElementById("map"), mapOptions);
google.maps.event.addListenerOnce($scope.map, 'idle', function () {
var marker = new google.maps.Marker({

Error:
incorrect marker location
How can I fix it?
You are passing the incorrect value to LatLng class as lat[i], lng[i]. The index position [i] is invalid.
So change your code like this:
lat = results[0].geometry.location.lat();
console.log("lat");
console.log(lat);
lng = results[0].geometry.location.lng();
console.log("lng");
console.log(lng);
console.log(JSON.stringify(results));
var markerPos = new google.maps.LatLng(lat, lng); // << Fix it here
Even, you don't have to define those lat and lng because you are getting it from a LatLng instance.
if (status == google.maps.GeocoderStatus.OK) {
console.log("results[0].geometry.location", results[0].geometry.location, JSON.stringify(results));
// No need to initialize again as the "results[0].geometry.location" is an instance of LatLng class itself
var markerPos = results[0].geometry.location;
var marker = new google.maps.Marker({
map: $scope.map,
animation: google.maps.Animation.DROP,
position: markerPos
});
}
See Geocoding Results:
results[]: {
types[]: string,
formatted_address: string,
address_components[]: {
short_name: string,
long_name: string,
postcode_localities[]: string,
types[]: string
},
partial_match: boolean,

AngularJS and GoogleMap

What I am trying is to get latitude and longitude dynamically as I move the marker on map. I found this solution:
google.maps.event.addListener(marker, 'dragend', function(evt){
window.alert(evt.latLng.lat()+"---"+evt.latLng.lng());
});
but its not returning me new values for lat and lng
Here is my code given:
$scope.$on('mapInitialized', function(event, map) {
var uluru;
$scope.postGoogle = function(google){
$http.get("https://maps.googleapis.com/maps/api/geocode/json?address="+google.address+google.city+google.state+google.zip+google.country+"&key="+google.apikey).
then(function(response) {
$scope.latitute = response.data.results[0].geometry.location.lat;
$scope.longitude = response.data.results[0].geometry.location.lng;
uluru = {lat: response.data.results[0].geometry.location.lat, lng: response.data.results[0].geometry.location.lng};
map.setCenter({lat: response.data.results[0].geometry.location.lat, lng: response.data.results[0].geometry.location.lng});
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h1 id="firstHeading" class="firstHeading">latitude and longitude</h1>'+
'<div id="bodyContent">'+
'<Span>'+map.getCenter()+'</span>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: uluru,
map: map,
draggable:true,
title: response.data.results[0].formatted_address
});
/* marker.addListener('click', function() {
infowindow.open(map, marker);
});*/
google.maps.event.addListener(marker, 'dragend', function(evt){
/* $scope.latitute = evt.latLng.lat().toFixed(3);
$scope.longitude = evt.latLng.lng().toFixed(3);*/
window.alert(evt.latLng.lat()+"---"+evt.latLng.lng());
//window.alert(this.getPosition().lat());
});
/*google.maps.event.addListener(marker, 'dragstart', function(evt){
//$scope.latitute = '<p>Currently dragging marker...</p>';
window.alert(evt.latLng.lat());
});
*/map.setCenter(marker.position);
marker.setMap(map);
}, function(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
//window.alert(google.address+"------"+google.apikey);
};
var numTiles = 1 << map.getZoom();
var projection = new MercatorProjection();
$scope.chicago = map.getCenter();
});
This is what I guess you are looking :
google.maps.event.addListener(marker, 'dragend', function() {
geocoder.geocode({'latLng': marker.getPosition()}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
if (results[0]) {
$('#address').val(results[0].formatted_address);
$('#latitude').val(marker.getPosition().lat());
$('#longitude').val(marker.getPosition().lng());
infowindow.setContent(results[0].formatted_address);
infowindow.open(map, marker);
}
}
});
});
Here's a little peice of JavaScript code what I used, to dynamically change lat and lng when marker is moved:
google.maps.event.addListener(marker, 'position_changed', function() {
lat = marker.getPosition().lat();
lng = marker.getPosition().lng();
$('#lat').val(lat);
$('#lng').val(lng);
});
and bottom 2 lines are assigning value to html input, to see, that values are changed

Markers click events are not working in mobile device

I have created google maps for Nearby food courts. In this markers are displayed in browser and clickable and giving info window data.But same thing coming to mobile, markers are displayed and when am clicking the marker(tap the marker) info window data is not displayed.I tried with so many forums and changes lot of code and debug but i couldn't find the solution.

So please anyone help in these regards.
The mousedown event was an improvement, however, on iOS the events still fired intermittently for me. After more investigation I found a solution that works 100% of the time by setting optimized: false when creating the marker in addition to using the mousedown event.
E.g.
var newMarker = new google.maps.Marker({
position: latLong,
map: map,
icon: 'https://maps.google.com/mapfiles/ms/icons/green-dot.png',
optimized: false
});
https://code.google.com/p/gmaps-api-issues/issues/detail?id=3834
I had the same issue. The problem was 'click' event is not triggering when we touch on the mobile screen. So I changed to 'mousedown' event. Now I am able to add markers
