I just can't understand why this simple example of MarkerManager shows no marker. I am opening a map at a center point and then adding one marker to the marker manager. When the map initializes there is no marker.
What am I missing?
Thanks, Rick

The documentation tells me that addMarker takes two arguments:
addMarker(marker:Marker, minZoom:Number, opt_maxZoom:Number) | None | Add a single marker to the map.
change the call in your code to:
mgr.addMarker(marker, 0);

can't seem to make this works
function initialize() {
var myLatlngBDG = new google.maps.LatLng(-6.913947, 107.633825);
var mapOptionsBDG = {
zoom: 5,
center: myLatlngBDG,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: 0
}
var mapBDG = new google.maps.Map(document.getElementById('map-BDG'), mapOptionsBDG);
var markerBDG = new google.maps.Marker({
position: myLatlngBDG,
map: mapBDG,
title: 'PT. Buana Citra Abadi Bandung'
});
};
google.maps.event.addDomListener(window, 'load', initialize);
the map itself is displayed, but the markes does not appear, and so is the title
according to this tutorial I need to write marker.setMap() to show marker, but as you can see I already write it
if the problem itself is not in the javascript then this might be the problem
the order including the script in HTML :
<html>
<<link rel="stylesheet" type="text/css" href="css/map.css"/>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=AIzaSyB8k-8ztQ6Vk34XP6OEBMZ7PryuMx8jjX8&callback=initMap"></script>
<script src="js/map.js"></script>
</html>
NEW PROBLEM
why is the map sometimes appears sometimes disappears? I mean when I refresh the page, it disappears, the I refresh several times and it re appears
It seems that everything is fine, take this code as an example and check yours maybe you find any difference
google.maps.event.addDomListener(window, "load", function () {
var myLatlngBDG = new google.maps.LatLng(-6.913947, 107.633825);
var mapOptionsBDG = {
zoom: 5,
center: myLatlngBDG,
mapTypeId: google.maps.MapTypeId.ROADMAP,
mapTypeControl: 0
}
var mapBDG = new google.maps.Map(document.getElementById("map-BDG"), mapOptionsBDG);
var markerBDG = new google.maps.Marker({
position: myLatlngBDG,
map: mapBDG,
title: 'PT. Buana Citra Abadi Bandung'
});
markerBDG.setMap(mapBDG);
});
#map-BDG{
width:500px;
height:300px;

I'm trying to create a multiple markers map. Every marker will have his infoWindow. I followed all the dev GoogleMaps information and infoWindow are still not appearing.
In this code that I'll give to you, I only create 3 markers with my own function "PintaMarker". This function creates a marker and adds its listener with the infowindow information and pushes the marker to my "markers Array" called markers.
When I finish the creation of the markers, I generate a MarkerClusterer to use and see all markers I create.
Can anyone take a look at my code and give me a hand on it?

Thank you!
The porblem ist that in your function pintaMarkerthe map1 object is null!!
The solution:
Pass the map object as a parameter to your pintaMarker like this:
pintaMarker(41.385, 2.154, 'hola', map1);
and update you function to:
function pintaMarker(lat,lng,html, map1){
var myLatLng = new google.maps.LatLng(lat, lng);
var marker = new google.maps.Marker({
position: myLatLng,
map: map1,
});
google.maps.event.addListener(marker, 'click', function(){
infowindow.setOptions({
content: html
});
infowindow.open(map1, marker);
console.log(infowindow);
});
markers.push(marker);
}
now the map object is available!

i wanna developing window contains map and allow user to mark his location and get longitude and latitude based on the marked location
any one has a suggestion ?
you can use google map v3 for this purpose..
Try this code, it creates a marker where the user clicks on the map

var map = new google.maps.Map(document.getElementById('map-canvas'),

google.maps.event.addListener(map, 'click', function (e) {
placeMarker(e.latLng, map);

function placeMarker(position, map) {

you will be requried to use maps click event to get lat/lag.
check below code for same.
GEvent.addListener(map, "click", function(overlay, latLng)
{
// display the lat/lng in your form's lat/lng fields
document.getElementById("latFld").value = latLng.lat();
document.getElementById("lngFld").value = latLng.lng();
//code for adding marker
//post/ajax call to save location in Database
});

I really have no clue on javascript and this is someone elses code, but does anyone know why it causes the above error in internet explorer?

If you open IE's developer tools, change to the script tag, and start debugging, then when the page refreshes and the error occurs, the developer tools will show a call stack headed by your call to add a listener to the drag event of a marker, and the __e3_ being referenced is a property of the marker, but you have not created the marker.
Move the addListener(marker ... call to within the initialize() function, after you've created the marker.
i have these two lines
map.panTo(respectiveMarker.getPosition());//Center in map the respective marker
infoWindow.open(map, respectiveMarker);
When infoWindow.open is executed the map pans to the edge.
If i remove this line the map pans to the marker as expected.
Any ideas?
Since you're using the v3 API you could simply prevent the infoWindow from shifting the map with the disableAutoPan option.
Complete example:

<div id="map" style="width: 200px; height: 200px"></div>
<script type="text/javascript">
var myLatlng = new google.maps.LatLng(37.44, -122.14);
var myOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var infowindow = new google.maps.InfoWindow({
content: 'Test',
disableAutoPan: true
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Test Marker'
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
});
</script>
</body>
</html>
Screenshot:
There is no equivalent to the disableAutoPan in the v2 API's GInfoWindowOptions, and I am not aware of any workarounds for this.
