I recently learn t to add custom markers to the Google maps. So i created a route with directions API. After that I added my own markers. Now i am facing a problem where both, the original one and the custom one are showing up. How can i remove the default markers to show my originals one.
Code I wrote to add custom markers
function addmarkers()
{
$.each(order,function(key,value)
{
geocoder.geocode( { 'address': waypts[value]}, function(results)
{
var source = 'images/markers/'+i+'.png';
var latlang = results[0].geometry.location;
var marker = new google.maps.Marker({
position: latlang,
map: map,
icon: source
});
});
});
};
I am calling this function just after the initialize() function
function initialize() // creating maps
{
google.maps.visualRefresh = true;
currentlocation = new google.maps.LatLng(mylat,mylong);
var mapoptions =
{
zoom: 14,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: currentlocation
}
map = new google.maps.Map(document.getElementById('map'),mapoptions);
addmarkers();
directionsDisplay.setMap(map);
};
Now you can see in the pic, I am getting both the default as well as the customized markers. Where is this going wrong ?

There are two places where i need to show google maps.
I'm using same code for both maps(I mean I'm reusing same code for both maps).
Below are links where you can find screen shots of those two maps.

I'm showing second map(map2) in bootstarp modal
first map(map1) is working fine. But in second map(map2), though I have used setCenter method, marker is not showing at center of the map(instead it is showing at top left corner).
what should i do to place marker at center of the map(in second map)?
below is my code..
initialize: function(options){
//initializing the geocoder
this.geocoder = new google.maps.Geocoder();
this.map;
},
//on show of the view
//onShow is a marionette method, which will be triggered when view is shown
onShow: function(){
var address = this.model.get("address");
//render the map with dummy latLang
this.renderMap();
//render the Map with Proper address
if(address!== ""){
this.renderMapWithProperAddress(address);
}
},
renderMap: function(){
var mapCanvas = document.getElementById("mapCanvas"), self = this,
mapOptions = {
center: new google.maps.LatLng(64.855, -147.833),//dummy latLang
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP,
zoomControl: false,
mapTypeControl: false,
streetViewControl:false
};
//initializing google map
self.map = new google.maps.Map(mapCanvas, mapOptions);
$("#myModal").on("shown.bs.modal",function(){
google.maps.event.trigger(self.map, "resize");
});
},
renderMapWithProperAddress: function(address){
var self = this,marker;
self.geocoder.geocode( { "address": address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
self.map.setCenter(results[0].geometry.location);
marker = new google.maps.Marker({
map: self.map,
position: results[0].geometry.location,
title: address
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
My guess, without seeing your code, is that you need to trigger a map resize event after the bootstrap modal has been shown.
Bootstrap modal
Maps events
$('#myModal').on('shown.bs.modal', function () {
google.maps.event.trigger(map, 'resize');
});
Edit:
Here is a complete and working example. As per my comment, you should 1) Trigger a map resize and 2) set the map center to your marker coordinates.
var center = new google.maps.LatLng(59.76522, 18.35002);
function initialize() {
var mapOptions = {
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP,
center: center
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var marker = new google.maps.Marker({
map: map,
position: center
});
}
$('.launch-map').on('click', function () {
$('#modal').modal({
backdrop: 'static',
keyboard: false
}).on('shown.bs.modal', function () {
google.maps.event.trigger(map, 'resize');
map.setCenter(center);
});
});
initialize();

I am trying to add geo-location to a custom public google map, I can't manage to get it to work. For example here is a custom public google map.
Lets say I wanted to add geo-targeting to that map. I have the following on the site which is directly off the google maps API website:
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true"></script>
as well as the following which I just changed '.getElementsById' to '.getElementsByClassName':
<script type="text/javascript">
var map;
function initialize() {
var mapOptions = {
zoom: 3,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementsByClassName('map-canvas'),
mapOptions);
// Try HTML5 geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
var pos = new google.maps.LatLng(position.coords.latitude,
position.coords.longitude);
var infowindow = new google.maps.InfoWindow({
map: map,
position: pos,
content: 'Location found using HTML5.'
});
map.setCenter(pos);
}, function() {
handleNoGeolocation(true);
});
} else {
// Browser doesn't support Geolocation
handleNoGeolocation(false);
}
}
function handleNoGeolocation(errorFlag) {
if (errorFlag) {
var content = 'Error: The Geolocation service failed.';
} else {
var content = 'Error: Your browser doesn\'t support geolocation.';
}
var options = {
map: map,
position: new google.maps.LatLng(60, 105),
content: content
};
var infowindow = new google.maps.InfoWindow(options);
map.setCenter(options.position);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
Then I call for the map which is in a lightbox:
<h2 class="dis">Where can I<br />get Rumble?</h2>
It displays the map fine, and asks to geo-target but I assume the reason its not working on this map is because its not included in the API.
I was hoping someone had a solution for this.
This is not an API based map. You can display the KML from that map on an API based map
Then use your geolocation code to center the map (depending on the ordering, you might need to use the preserveViewport:true option on the KmlLayer). Relevant code below, see the documenation for more examples and information.
This is in your existing page (leave your version)
var myOptions = {
zoom: 5,
center: new google.maps.LatLng(0,0),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
Add this to display the data from your "custom map":
var kmlLayer = new google.maps.KmlLayer("https://maps.google.ca/maps/ms?ie=UTF8&msa=0&output=kml&msid=202458571791405992786.0004b9061a3fcd9461d42");
kmlLayer.setMap(map);
i am working on google maps, what i want to do is to click on the map it add a marker to the map its working fine but the problem is that i need to move the same marker to a new place if i click some where else instead of new marker. and also when i click on any point it give me the address of that place in a text field
here is my code
<script type="text/javascript">
var map;
var markersArray = [];
function initialize() {
var haightAshbury = new google.maps.LatLng(37.7699298, -122.4469157);
var mapOptions = {
zoom: 7,
center: haightAshbury,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
google.maps.event.addListenerOnce(map, 'click', function(event) {
addMarker(event.latLng);
});
}
function addMarker(location) {
marker = new google.maps.Marker({
position: location,
map: map
});
markersArray.push(marker);
}
// Removes the overlays from the map, but keeps them in the array
function clearOverlays() {
if (markersArray) {
for (i in markersArray) {
markersArray[i].setMap(null);
}
}
}
}
You can call clearOverlays anytime you create a new marker.this way you hide the previous marker and only the new is shown.
another way is to have a var marker just as you have a var map. you can edit the markers position in addMarker.
as far as geocoding is concerned take a look at this
I have an application where I'm using the Google Map API to display markers for posts made by users using their lat/lon. I employed the MarkerClusterer capability for better organization of the markers, which works but with a bug of sorts.
Essentially, I've been testing this at home so the lat/lon has been the same for all test posts. Before using MarkerClusterer, zooming far into the map would eventually reveal all the markers. Unfortunately, using the MarkerClusterer, if there is, for example, a "5" listed for the number of markers that are very close together such as these test posts, clicking on the cluster reveals nothing. No markers ever appear when these are very close together. To reiterate, these markers do appear without the MarkerClusterer.
I upgraded to MarkerClustererPlus v2.0.9 per another post that described other issues with the MarkerClusterer but that hasn't solved the problem.
Any insight into this issue would be greatly appreciated.
Edit: geocodezip suggested the overlappingmarkerspidifier, which sounds great, but my code is fairly involved and I'm not sure how to incorporate it. Any insight much appreciated. Code follows:
function mainGeo()
{
if (navigator.geolocation)
{
navigator.geolocation.getCurrentPosition( mainMap, error, {maximumAge: 30000, timeout: 10000, enableHighAccuracy: true} );
}
else
{
alert("Sorry, but it looks like your browser does not support geolocation.");
}
}
var stories = {{storyJson|safe}};
var geocoder;
var map;
var markers = [];
function loadMarkers(stories){
for (i=0;i<stories.length;i++) {
var story = stories[i];
if (story.copy.length > 120) {
story.copy = story.copy.substring(0, 120) + "...";
}
(function(story) {
var pinColor = "69f2ff";
var pinImage = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=S|" + pinColor,
new google.maps.Size(21, 34),
new google.maps.Point(0,0),
new google.maps.Point(10, 34));
var point = new google.maps.LatLng(story.latitude, story.longitude);
var marker = new google.maps.Marker({position: point, map: map, icon: pinImage});
var infowindow = new google.maps.InfoWindow({
content: '<div >'+
'<div >'+
'</div>'+
'<h2 class="firstHeading">'+story.headline+'</h2>'+
'<div>'+
'<span>'+story.author+'</span><br />'+
'<span>'+story.city+'</span><br />'+
'<span>'+story.topic+'</span><br />'+
'<p>'+story.date+'</p>'+
'<p>'+story.copy+'</p>'+
'<p><a href='+story.url+'>Click to read story</a></p>'+
'</div>'+
'</div>'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,this);
});
markers.push(marker);
})(story);
}
}
function mainMap(position)
{
geocoder = new google.maps.Geocoder();
// Define the coordinates as a Google Maps LatLng Object
var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var width = window.innerWidth - 80;
size = width;
// Prepare the map options
var mapOptions =
{
zoom: 15,
center: coords,
mapTypeControl: false,
navigationControlOptions: {style: google.maps.NavigationControlStyle.SMALL},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// Create the map, and place it in the map_canvas div
map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
// Place the initial marker
var marker = new google.maps.Marker({
position: coords,
map: map,
title: "Your current location!"
});
loadMarkers(stories);
var markerCluster = new MarkerClusterer(map, markers);
}
function codeAddress() {
var address = document.getElementById("address").value;
geocoder.geocode( { 'address': address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
map.setCenter(results[0].geometry.location);
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
function error() {
alert("You have refused to display your location. You will not be able to submit stories.");
}
mainGeo();
Perhaps this post in the v3 group: Overlapping markers on your Google Map? Meet OverlappingMarkerSpiderfier might help:
Sounds like the OverlapingMarkerSpiderifier solves your problem.
I wanna simply get markers from a kml file and show them on a map, but add "mouseover" for tooltip, not click
using this code, but it don't work (works if i use click)
function initialize() {
var latlng = new google.maps.LatLng(53.477876, -2.471289);
var myOptions = {
zoom: 5,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
//kml begin
var nyLayer = new google.maps.KmlLayer('http://code.nebtron.com/kml2.kml', {suppressInfoWindows: false});
nyLayer.setMap(map);
google.maps.event.addListener(nyLayer, "mouseover", function(kmlEvent) {
var text = kmlEvent.featureData.description;
showInDiv(text);
});
function showInDiv(text) {
var sidediv = document.getElementById('contentWindow');
sidediv.innerHTML = text;
}//kml end
}

As pointed out here, there is no mouseover event for KMLLayers. But maybe you could use a polygon. Here's a link.
Hope this helps!
