How to add info window for custom overlays? - maps

I have implemented a custom overlay. I want to add an event which will pop an info window when I click the overlay.
function initMap() {
var map = new google.maps.Map(document.getElementById('okmap'), {
zoom: 4,
center: {lat: 35.0000, lng: 103.0000}
});
for (var n in nodes) {
var myMarker = new MyMarker(map, {latlng: new google.maps.LatLng(nodes[n][0], nodes[n][1]),
image: 'assets/img/light-green.png',
labelText: (Math.random() * 100).toFixed(0)});
markers.push(myMarker);
var infowindow = new google.maps.InfoWindow({
content: n
});
myMarker.addListener('click', function() {
infowindow.open(map, myMarker);
});
}
}
But it is not working!

I faced a simliar problem some time back. Here are two things that helped me.
I am considering the main overlay element to be a div.
In your MyMarker.draw function make sure that you are using a pane that has access to the DOM events.e.g.
var panes = this.getPanes();
panes.overlayMouseTarget.appendChild(div);
See https://developers.google.com/maps/documentation/javascript/customoverlays#initialize for more details.
Make sure you define an event listener, also in the MyMarker.draw function.
google.maps.event.addDomListener(div, "click", function(event) {
google.maps.event.trigger(self, "click");
});

Display parsed data in info window in Google Maps

I am having trouble trying to display the event name from an array of objects in a parsed JSON file within Google Maps Ionic framework. Right now I have the markers displaying for each event with a simple string called "testing" which displays fine. The problem is I am unsure of how to display each events name within this info window and not the string I made. Any help would be appreciated. I'll post the sample image I have now as well as the info window functionality below. Thanks!
what I have displaying now:
here
marker/info window functionality:
getMarkers(){
//this.http.get('assets/data/markers.json').map((res)=>res.json()).subscribe(data=>{
this.http.get('http://app.toronto.ca/cc_sr_v1_app/data/edc_eventcal_APR?limit=500').map((res)=>res.json()).subscribe(data=>{
this.addMarkersMap(data);
});
}
addMarkersMap(markers){
for(let marker of markers)
{
var loc = marker.calEvent.locations[0]['coords'];
console.log(loc);
marker = new google.maps.Marker({
position: loc,
map: this.map,
});
var infoWindow = new google.maps.InfoWindow({
content: markers.eventName
});
google.maps.event.addListener(marker, 'click', function(str)
{
return function() {
infoWindow.setContent(str);
infoWindow.open(this.map, marker);
}
}(markers.eventName));
}
}
I correct myself. You could benefit from a closure here.
Use a self-calling function to seal your parameter to the infowindow:
google.maps.event.addListener(marker, 'click', function(str)
{
return function() {
infoWindow.setContent(str);
infoWindow.open(this.map, marker);
}
}(markers.calEvent.eventName));

Google Map Javascript Api, Angular, Dynamicly Loaded Page

What happened past weeks i don't know if google messed things up again. My map stopped working.
I transferred the app Angular for routes. When the contact page loads, initializeMap function called.
I got new browser api key from google console which is not like old. I enabled Javascript Map Api. I entered my URLs in credential.
Sometimes it gives error invalidkey*** but only sometimes.
It works on my domain if i put everything in one single file.
It also works on codepen. I don't know why? There is no error to debug this thing. My beloved javascript.
http://codepen.io/emrahatilkan/pen/bVwzrR
Edit: This is about angular definitely.
Google Map Link in index.html:
<script src="https://maps.googleapis.com/maps/api/js?key=MY_KEY"></script>
My URL: index.html/#/contact
I don't know if it is relevant but contact.html is inside pages/ folder.
My Code is in main.js:
function initializeMap() {
console.log('init map'); //this outputs to console
var mapOptions = {
center: { lat: 39.7944417, lng: 30.4935026 },
zoom: 16,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scaleControl: false,
scrollwheel: false
};
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
title: 'Some Title'
});
var infowindow = new google.maps.InfoWindow({
content: '<h5>Some Title</h5>'
});
google.maps.event.addListener(marker, 'click', function () {
infowindow.open(map, marker);
});
}

How to work with maps in different views

I'm trying to show different maps in different views but charging 1 on 1 map view, switch to another map not load, there is no mistake to launch the browser so I could not decide because I can not keep showing other maps. I'm doing as follows:
$scope.cargarUbicacion = function () {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function (position) {
latitud_actual = position.coords.latitude;
longitud_actual = position.coords.longitude;
console.log(latitud_actual);
console.log(longitud_actual);
var mapOptions = {
center: new google.maps.LatLng(latitud_actual, longitud_actual),
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel: false
};
map = new google.maps.Map(document.getElementById("mapa_ubicacion"), mapOptions);
$scope.setMarker(map, new google.maps.LatLng(latitud_actual, longitud_actual), 'Yo', '');
});
}
}
$scope.setMarker = function(map, position, title, content) {
var marker;
var markerOptions = {
position: position,
map: map,
title: title,
icon: 'http://maps.google.com/mapfiles/ms/icons/green-dot.png'
};
marker = new google.maps.Marker(markerOptions);
markers.push(marker); // add marker to array
google.maps.event.addListener(marker, 'click', function () {
// close window if not undefined
if (infoWindow !== void 0) {
infoWindow.close();
}
// create new window
var infoWindowOptions = {
content: content
};
infoWindow = new google.maps.InfoWindow(infoWindowOptions);
infoWindow.open(map, marker);
});
}
I am using this code in multiple controllers, my idea is encapsulated and can occupy the same code 1 time in several views. Whenever I change the id map to avoid that problem, thinking that this was the cause that did not load the map.
Any idea how to do what I need or that is failing to load maps?
Thank you.
I personnaly do the following :
The code taht you want to reuse put it into a global variable such as :
Then into your control, you can extend it with this mapExtend
global.MapExtend = function($scope, $rootScope, leafletData) {
// ... all your functions to reuse
};
// In your main controler, extend it with your map capabilities with angular.extend
angular.extend(myCtrl, new MapExtend($scope, $rootScope, leafletData));

AngularJS Leaflet getMap() doesn't work

After adding Leaflet to my AngularJS app:
<leaflet id="map" defaults="defaults" center="center" bounds="bounds" controls="controls" event-broadcast="events"></leaflet>
And setting it up:
// Initialise the feature group to store editable layers
var drawnItems = new L.FeatureGroup();
// Initialise the draw control
var drawControl = new L.Control.Draw({
position: 'topright',
edit: {
featureGroup: drawnItems
}
});
// Configure Leaflet
angular.extend($scope, {
defaults: {
zoomControlPosition: 'topright',
minZoom: 3,
tileLayerOptions: {
detectRetina: true,
reuseTiles: true,
attribution: 'OpenStreetMaps'
}
},
center: {},
controls: {
custom: [drawControl]
},
events: {
map: {
enable: ['click']
}
}
});
Following this code it doesn't get evaluated (no error shown though):
leafletData.getMap().then(
function (map) {
alert('I have accessed the map.');
}
);
This should show me an alert straight away, although nothing happens.
If I delay this previous code, for example, running it in a function on a button click, it works!
Does anyone knows what could be a problem?
Seeing example, it should work: https://github.com/tombatossals/angular-leaflet-directive/blob/master/examples/control-draw-example.html
PARTLY SOLVED
Removing ID from leaflet HTML tag solved the problem. Must be a bug.
You are supposed to pass the id specified in the <leaflet> tag to getMap() function.
In your example, the id is map. You would pass it like this:
leafletData.getMap("map").then(
function (map) {
alert('I have accessed the map.');
}
);

How to open the infoWindow google map is using?

I have a Goole map in a contact page in which i would like to show the infoWindow used on Google map.
Go to that link : Gmap
And click on the marker. A info window should appear.
My question is : How do I make the same thing append on my Website ?
Ps : I know how to build a google.maps.InfoWindow object, but i don't want to create the html myself.
This part of the Google Map's Docs explains this: https://developers.google.com/maps/documentation/javascript/overlays#InfoWindows
Define your lat long coordinate
var myLatlng = new google.maps.LatLng(-25.363882,131.044922);
Set your map otions
var mapOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
Initialize your map
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
Set the content for your infowWindow
var contentString = '<b>Set content for infowindow here in HTML<b>';
Intialize your infoWindow with the content string.
var infowindow = new google.maps.InfoWindow({
content: contentString
});
Place your marker at the previously defined marker on the above defined map
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Uluru (Ayers Rock)"
});
And finally just bind the 'click' event on the marker to the infowindow you created.
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
