I have a problem with the position of the markercluster's infoWindow. It doesn't show up at the marker position. Instead it is positioned on the upper left corner of the map. Here is my code:
<script type="text/javascript">
function initialize(cities) {
var mapOptions = {
center: new google.maps.LatLng(48.220, 15.199),
zoom: 9,
mapTypeId: google.maps.MapTypeId.ROADMAP,
};
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
var markers=[];
var markerCluster = new MarkerClusterer(map, markers, {zoomOnClick: false});
//markerCluster should be always above the geocoder-->
geocoder = new google.maps.Geocoder();
for (var i = 0; i < cities.length; i++) {
var city = cities[i];
geocoder.geocode({'address': city.city+" Niederösterreich"}, function(results, status){
if (status == google.maps.GeocoderStatus.OK) {
position=results[0].geometry.location;
var marker = new google.maps.Marker({
map: map,
position: position,
title: "Ort: "+city.city + "\nBeitrag: " + city.title +"\nRed.: "+ city.reporter +"\nDatum: "+ city.storydate,
});
// below code alway lies inside the loop
markers.push(marker);
markerCluster.addMarker(marker);
}
});
};
// Listen for a cluster to be clicked
google.maps.event.addListener(markerCluster, 'clusterclick', function(cluster) {
var markers = markerCluster.getMarkers();
var content = '';
for (var i = 0; i < markers.length; i++) {
var marker = markers[i];
content += marker.title;
content += ("<br>");
};
// Convert lat/long from cluster object to a usable MVCObject
var info = new google.maps.MVCObject;
var infowindow = new google.maps.InfoWindow();
// infowindow.setPosition(this.markerCluster.getCenter());
// infowindow.setPosition(latLng);
infowindow.close();
infowindow.setContent(content);
infowindow.open(map, info);
google.maps.event.addListener(map, 'zoom_changed', function() { infowindow.close() });
});
}
</script>
Your MVCObject doesn't have any properties. According to the documentation, if you pass the optional anchor argument into the function .open, it must expose a LatLng position property, yours doesn't (as it doesn't have any properties, it can't expose any).
open(map?:Map|StreetViewPanorama, anchor?:MVCObject)
Return Value: None
Opens this InfoWindow on the given map. Optionally, an InfoWindow can be associated with an anchor. In the core API, the only anchor is the Marker class. However, an anchor can be any MVCObject that exposes a LatLng position property and optionally a Point anchorPoint property for calculating the pixelOffset (see InfoWindowOptions). The anchorPoint is the offset from the anchor's position to the tip of the InfoWindow.
The simplest solution is to not use the anchor argument, set the position of the infowindow directly.
google.maps.event.addListener(markerCluster, 'clusterclick', function (cluster) {
var markers = cluster.getMarkers();
var content = '';
for (var i = 0; i < markers.length; i++) {
var marker = markers[i];
content += marker.title;
content += ("<br>");
}
var infowindow = new google.maps.InfoWindow();
infowindow.setPosition(cluster.getCenter());
infowindow.setContent(content);
infowindow.open(map);
google.maps.event.addListener(map, 'zoom_changed', function () {
infowindow.close();
});
});

I have a number of markers and I want to show the markers in a list outside of the map. How can this be achieved using javascript? I am new to Javascript so help is appreciated. Code I have currently below, this is all working as expected apart from listing the map marker information.
I idea is that a list will appear depending on the option chosen in the dropdown for counties.
//List of Counties
var counties = [{
name: "Armagh",
code: "am",
zoom : 8,
center: {
lat: 54.274911,
lng: -6.626583
}
}, {
name: "Cork",
code: "c",
zoom : 8,
center: {
lat: 51.904246,
lng: -8.474038
}
}];
//List of Practices
var practice = [{
name: "Cross Veterinary Clinic",
position: {
lat: 54.07531,
lng: -6.60590
},
code: "am",
address: "8 Dundalk Road, Crossmaglen, Co. Armagh",
vet: "Carol Peterson",
programme: ['bvd', 'jd']
}, {
name: "Keltic Veterinary",
position: {
lat: 52.35386,
lng: -8.68204
},
code: "c",
address: "Charleville Town Centre, Bakers Road, Charleville, Co. Cork",
vet: "Gerald Gonzales",
programme: ['cck', 'bvd']
}];
var countyselect = document.getElementById('county')
countyselect.addEventListener("change", onCountySelect);
//render map
function initialize() {
var options = {
center: {
lat: 53.2734,
lng: -7.77832031
},
zoom: 6.5
};
map = new google.maps.Map(document.getElementById('map'), options);
marker = renderMarker();
}
function renderMarker() {
for (var i = 0; i < practice.length; i++) {
var marker = new google.maps.Marker({
position: practice[i].position,
title: practice[i].name,
map: map,
});
inforwindow(marker, map);
}
}
function inforwindow(marker, map) {
var infowindow = new google.maps.InfoWindow(); {
google.maps.event.addListener(marker, 'click', function(renderMarker) {
infowindow.setContent(marker.getTitle());
infowindow.open(map, marker);
});
}
}
function onCountySelect() {
let countySelect = document.getElementById("county");
let selectedCounty = countySelect.options[countySelect.selectedIndex];
let countyFound = (counties.find(({ name }) => name === selectedCounty.value));
if (selectedCounty.value === "all") {
map.setCenter({ lat: 53.2734, lng: -7.77832031 });
map.setZoom(6.5);
} else {
map.setCenter(countyFound.center);
map.setZoom(countyFound.zoom);
}
}
function resultsList() {
if (selectedCounty.value === "all") {
let countySelect = document.write(`<h3>${practice.name}</h3><p>${practice.address}</p><p>${practice.vet}</p>`);
}
}
I'm not sure at all from your code what your plan is with markers, or whether you intend to make items in the list clickable so that they highlight a specific marker on the map. But in any case, here's code to do what you asked - to create a list of relevant practices when a county is selected. I've dropped in some hacky test HTML just as it's easier to test.
Hopefully this will get you on the right path.
A couple of notes - you have used the backtick, ie using ` and ${variable} approach to rendering some content - this may not work on older browsers directly.
Also, please excuse the mix of single and double quotes - that's a matter of taste but I didn't see the point in going back and changing everything you had done. Good luck!

I'm going to initalize infowindows (for google map markers) through angular controller (i'm using ng-map module)
NgMap.getMap().then (map) ->
$scope.map = map
for marker in markers
latLng = new (google.maps.LatLng)(marker.latitude, marker.longitude)
#initialize infoWindows through google map api, not ng-map module
contentString = 'is an example string'
infoWindow = new (google.maps.InfoWindow)(content: contentString)
$scope.dynMarkers.push new (google.maps.Marker)(position: latLng)
marker.addListener 'click', ->
infoWindow.open map, marker
$scope.markerClusterer = new MarkerClusterer(map,$scope.dynMarkers, {})
I have an error in console:
marker.addListener is not a function
I can't use an ng-map 'infowindow' DOM element in my view.
What's wrong?
marker object needs to be of google.maps.Marker type, try to replace:
$scope.dynMarkers.push new (google.maps.Marker)(position: latLng)
marker.addListener 'click', ->
infoWindow.open map, marker
with
markerObject = new (google.maps.Marker)(position: latLng) #<-Marker object
$scope.dynMarkers.push markerObject
markerObject.addListener 'click', ->
infoWindow.open map, markerObject
Example
angular.module('mapApp', ['ngMap'])
.controller('mapController', function ($scope, NgMap) {
NgMap.getMap().then(function (map) {
$scope.map = map;
$scope.dynMarkers = [];
$scope.markers.forEach(function (marker) {
var latLng = new google.maps.LatLng(marker.latitude, marker.longitude);
var contentString = 'is an example string'
var infoWindow = new (google.maps.InfoWindow)({ content: contentString });
var dynMarker = new google.maps.Marker({ position: latLng });
$scope.dynMarkers.push(dynMarker);
google.maps.event.addListener(dynMarker, 'click', function () {
infoWindow.open(map,dynMarker);
});
});
var mcOptions = { imagePath: 'https://cdn.rawgit.com/googlemaps/js-marker-clusterer/gh-pages/images/m' };
$scope.markerClusterer = new MarkerClusterer(map, $scope.dynMarkers, mcOptions)
});

I am trying new to localStorage, and I am trying to save the markers that the user can create on the map.
I created this function to place markers and delete them:
var redmarker = L.icon({
iconUrl: 'http://icons.iconarchive.com/icons/paomedia/small-n-flat/48/map-marker-icon.png',
iconSize: [48, 48], // size of the icon
iconAnchor: [24, 48], // point of the icon which will correspond to marker's location
popupAnchor: [-2, -48] // point from which the popup should open relative to the iconAnchor
});
var popup = L.popup();
// On map click shows coordinates X, Y
function onMapClick(e) {
var geojsonFeature = {
"type": "Feature",
"properties": {},
"geometry": {
"type": "Point",
"coordinates": [e.latlng.lat, e.latlng.lng]
}
}
var marker;
L.geoJson(geojsonFeature, {
pointToLayer: function(feature, latlng){
marker = L.marker(e.latlng, {
title: "Resource Location",
alt: "Resource Location",
riseOnHover: true,
draggable: true,
icon: redmarker
}).bindPopup("<<span>X: " + e.latlng.lng + ", Y: " + e.latlng.lat + "</span><br><a href='#' id='marker-delete-button'>Delete marker</a>");
marker.on("popupopen", onPopupOpen);
return marker;
}
}).addTo(map);
}
function onPopupOpen() {
var tempMarker = this;
$("#marker-delete-button:visible").click(function () {
map.removeLayer(tempMarker);
});
}
map.on('click', onMapClick);
I am not familiar with localStorage, this is new to me. Also I am trying to make the popup editable, an user input there for the user name the marker.
I saw this example of input:
http://tahvel.info/simpleStorage/example/
Something like that.
A working example of my function: http://fiddle.jshell.net/2g4h5eu5/1/
Can someone help me save the markers in localStorage?
Also my problem is that I don't know what render's the markers on leaflet after I click, so I don't know exactly what I need to save in local storage to retrieve those markers.
you can use the following functions to manage your localStorage
localStorage.setItem('favoriteflavor','vanilla');
var taste = localStorage.getItem('favoriteflavor');
// -> "vanilla"
localStorage.removeItem('favoriteflavor');
var taste = localStorage.getItem('favoriteflavor');
// -> null
check this link
also you can use jQuery Storage API plugin to make things more cross-browser
http://fiddle.jshell.net/thesane/2g4h5eu5/29/
/// Load markers

{
var markers = localStorage.getItem("markers");
if(!markers) return;
markers = JSON.parse(markers);

I did not find the solution.
Please need help
Your object code appears malformed: there is an unmatched ] character on line 8. Try deleting this character and running it.
Currently, I am displaying 500-600 Markers on Google map, with their names as tooltip. Now,
I need to display the tool-tip of all overlapping markers as comma-separated i.e. Marker1, Marker2, Marker3 etc. if Marker1, Marker2, Marker3 are overlapped on map.
I found many other different examples on google map at internet especially at GeoCodeZip, but not of my requirement.
if this requirement is once filled, Am afraid of performance issues on zoom changed events, as tooltip needed to be updated (if overlapping is changed).
Update1 : I have already show Overlapping Marker spiderfier to client but not acceptable.
Does anyone have right path or working example ?
Thanks

The core of this is to find the pixel distance between LatLngs. Then before adding each marker check the pixel distance between it and any existing markers. If there is another marker nearby add to the title otherwise create a new marker. jsFiddle
