How to set the marker position constant on window resize on google maps?

I recently started exploring google maps api. I stumbled upon panby function of google maps api. What I am trying to do is, when my map is loaded initially, the marker should be on the right as shown in the attached image.
Attached screenshot of initial load
However, I want to add a listener for the marker to stay on the right on window resize but do not know what to write in the listener function .Please help me this. Thanks in advance. Here is my code so far.
onAfterRendering: function() {
var myLatlng = new google.maps.LatLng(12.979172,77.715402);
var mapOptions = {
center: myLatlng ,
zoom: 12,
disableDefaultUI: true,
zoomControl: true
};
var x = this.byId("mapCanvas").getDomRef();
map = new google.maps.Map(x, mapOptions);
map.panBy(-300,0);
google.maps.event.addDomListener(window, "resize", function() {
var location= marker.getPosition();
google.maps.event.trigger(map, "resize");
});}

You can recenter the map to the known marker position and then pan left. Something like (untested):
...
map.panBy(-300,0);
var markerLocation= marker.getPosition(); //if you don't have it elsewhere
google.maps.event.addDomListener(window, "resize", function() {
map.setCenter(markerLocation)
map.panBy(-300,0);
google.maps.event.trigger(map, "resize");
});}

JavaFX: Google Maps in a WebPane - Moving a Marker leaves old one behind

I've got an application that runs an instance of the Google Maps API in a JavaFX WebView, and am trying to allow the user to move the map marker around.
I've tried the following:
google.maps.event.addListener(map, 'click', function(event) {
marker.setPosition(event.latLng);
}
As well as:
google.maps.event.addListener(map, 'click', function(event) {
marker.setMap(null);
marker = null;
marker = new google.maps.Marker({
position:event.latLng,
map: map
});
}
Both of these implementations create the same issue: Clicking on the map creates a marker at the new position, but the old position marker remains on the screen as well. Moving the map around and forcing the section with the old marker to reload removes that marker, leading me to believe this is not an issue of implementation but a bug in the web browser's handling of it. Any way to fix this, so that there isn't a duplicate marker left behind?

I think this is a matter of code implementation. Try this. Tested this on jsfiddle and it's working perfectly.
function initMap() {
var myLatLng = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: {lat: -25.363882, lng: 131.044922 }
});
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
draggable: true,
});
google.maps.event.addListener(map, 'click', function(e) {
updateMarkerPosition(marker,e);
});
}
function updateMarkerPosition(marker, e){
marker.setPosition(e.latLng);
}
If this seamless execution is not reflected in your JavaFX application, then it's not Google Maps API that has the problem.

Wrong position of infowindow on small zoom levels. Google maps api v3

On small zoom levels one place will be displayed twice or more (world map is repeated horizontally). When I place marker on map with coordinates (e.g. -32.05604, 115.74718) I will see it on map more than once. It's normal.
But if I try to show infowindow on mouse hover I will get wrong behaviour. Infowindow will be always showed near one of my markers and never near other, without relation what marker was under mouse cursor.
See example here: (try to move mouse to left marker on map).

How to show infowindow for marker which under mouse?
My code:
function initialize() {
var myLatLng = new google.maps.LatLng(-32.05604, 115.74718),
myOptions = {
zoom: 1,
center: new google.maps.LatLng(-32.05604, 0)
},
map = new google.maps.Map(document.getElementById('map-canvas'), myOptions),
marker = new google.maps.Marker({
position: myLatLng,
map: map
});
marker.setMap(map);
var iw = new google.maps.InfoWindow();
marker.addListener('mouseover', function() {
iw.setContent('InfoWindow');
iw.open(map, this);
});
marker.addListener('mouseout', function() {
iw.close();
});
}
initialize();

I'm afraid there is nothing you can do to get the desired result(the position is correct, so when the position exists multiple times on a map, the API has to make a decision).
What you can do: set the optimized-option of the marker to false, then they will not be repeated at lower zoom-levels

How to get onclick event of marker generated by getroute

In this jsfiddle is simplified version of my js: http://jsfiddle.net/Drecker/2m4kvxb8/4/ Note that interesting part of the jsfiddle is only showRoute method. And method showMarker only shows desired behavior on normal marker.
Basically I generate a route via gmap3 getroute with some waypoints. After clicking on a waypoint I need to open a small infobox with more custom information of that point - so basically somehow get onclick event of such waypoint (with some identification of that waypoint so I would be able to get proper information). I'm able to achieve desired behavior on a separate marker (as you can see in the jsfiddle - that's the fully functional separate marker on the top left), but not on the markers generated by directionrenderer.
Furthermore please note that my waypoints have stopover: false and such markers for some reason ignore (some) options like title, as you can see in jsfiddle.
Any help is very appreciated - I've tried several things none of them works.

Hope you are using the google APIs library some version, in case something like this
<script src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places,geometry" type="text/javascript"></script>
You have one div space to show the map, say
<div id="map" style="width: 700px; height: 600px;"></div>
So you can use this for adding listener on markers
//location is an array variable where you store your co ordinates
//code to show map
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(locations[0].latitude, locations[0].longitude),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
//adding listener
var marker,i;
var infowindow = new google.maps.InfoWindow();
google.maps.event.addListener(marker, 'click', (function (marker, i) {
return function () {
infowindow.setContent(locations[i].city);
infowindow.open(map, marker);
}
})(marker, i));
where
marker
is the varible which will be something like this,
//adding marker
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude),
map: map
});
Hope from above you got some idea, might be helpful for you with your problem

There is no such option, according to the documentation and a lot of similar questions here on the stackoverflow, you can't bind click action to waypoints.
I have a workaround for that problem. The main idea is to add markers instead of waypoints and change their icon. Marker has much more options than waypoint. So I removed waypoints and added markers. Note that you have to be much more precise when adding marker's location
options without waypoints:
options: {origin: {lat:49.9, lng: 14.9},
destination: {lat: 50.1, lng: 15.1},
travelMode: google.maps.DirectionsTravelMode.DRIVING
},
added markers with a new icon and click event:
marker:{
values:[
{latLng:[49.96485, 14.88392], data:"Waypoint1", options:{icon: "http://mt.google.com/vt/icon/name=icons/spotlight/directions_transfer_icon_10px.png&scale=1"}},
{latLng:[49.97730, 14.88185], data:"Waypoint2", options:{icon: "http://mt.google.com/vt/icon/name=icons/spotlight/directions_transfer_icon_10px.png&scale=1"}}
],
options:{
draggable: false
},
events:{
click: function(marker, event, context){
var map = $(this).gmap3("get"),
infowindow = $(this).gmap3({get:{name:"infowindow"}});
if (infowindow){
infowindow.open(map, marker);
infowindow.setContent(context.data);
} else {
$(this).gmap3({
infowindow:{
anchor:marker,
options:{content: context.data}
}
});
}
}
}
}
Here is my workaround for that problem : DEMO

Google Maps API v3: Close infowindow when DOM element is clicked

I'm playing around with Google maps for the first time, so I looked at a nice tutorial over at CSS Tricks: http://css-tricks.com/google-maps-slider/ I like working with jQuery better than pure JS, and this tutorial makes a nice way to click on a place in a list to display the marker in the map.
I liked it that way, but I need to add infowindows to the marker. Which I did, but when I click on a place on the list and the map pans away, the infowindow stays open! I think it's because I need to attach the infowindow.close() to the event of clicking on a "#locations li".
Here's my code, which runs on document.ready:
$(function() {
var chicago = new google.maps.LatLng(41.924832, -87.697456),
pointToMoveTo,
first = true,
curMarker = new google.maps.Marker({}),
$el;
var myOptions = {
zoom: 10,
center: chicago,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map($("#map_canvas")[0], myOptions);
$("#locations li").click(function() {
$el = $(this);
if (!$el.hasClass("hover")) {
$("#locations li").removeClass("hover");
$el.addClass("hover");
if (!first) {
// Clear current marker
curMarker.setMap();
// Set zoom back to Chicago level
// map.setZoom(10);
}
// Move (pan) map to new location
function move(){
pointToMoveTo = new google.maps.LatLng($el.attr("data-geo-lat"), $el.attr("data-geo-long"));
map.panTo(pointToMoveTo);
}
move();
// Add new marker
curMarker = new google.maps.Marker({
position: pointToMoveTo,
map: map
});
// Infowindow: contenido
var contentString = '<p>'+$el.find("h3").html()+'</p>';
contentString += 'hola' ;
var infowindow = new google.maps.InfoWindow(
{
size: new google.maps.Size(150,50),
content: contentString
});
// On click, zoom map
google.maps.event.addListener(curMarker, 'click', function() {
//map.setZoom(14);
infowindow.open(map,curMarker);
});

It looks like you're creating a new InfoWindow for each marker. Quoting from the Google Maps API Docs:
If you only want one info window to display at a time (as is the behavior on Google Maps), you need only create one info window, which you can reassign to different locations or markers upon map events (such as user clicks).
Therefore, you may simply want to create one InfoWindow object just after you initialize your map, and then handle the click event handler as follows:
google.maps.event.addListener(curMarker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, curMarker);
});
Then the InfoWindow should automatically close when you click on a new marker without having to call the close() method.
