Google maps event - get parent of clicked element

I have function with which I'm making new object 'claster'. In every claster is marker from google maps API. I want to click on this marker and get access to claster.icons[]. I'm binding click event in my function declaration. How to do it?
CODE
function newClaster(_center){
this.centerIco = _center;
this.center = this.centerIco.getPosition();
this.icons = [];
this.icons.push(this.centerIco);
this.addIcon = function(_icon){this.icons.push(_icon)};
this.marker = new google.maps.Marker({
position : this.center,
icon : {
url : 'map/circle.png',
scaledSize : new google.maps.Size(40,40),
size : new google.maps.Size(40,40),
},
map:map,
});
this.setCenter = function(ctr){
this.centerIco = ctr;
this.center = ctr.getPosition();
}
this.findCenter = function(){
this.centerIco = this.icons[parseInt((this.icons.length)%2)];
this.center = this.centerIco.getPosition();
}
google.maps.event.addListener(this.marker, 'click', function(){
this.icons
});
}
I'm binding click on marker.

add a function and send the marker to it on click, then you can get the icons by accessing the marker object:
google.maps.event.addListener(this.marker, 'click', getIcons(this));
function getIcons(marker){
console.log(marker.icons);
}

google maps API3 drawing custom map icon based on user selection

Im working on a google maps plugin (there's always room for another right?) and I'm drawing a preview of the map my users will be inserting into their content. Im able to draw everything I set out to, custom content in the info window, setting the location (through places.Autocomplete) etc. The one thing that is escaping me is custom map icon isn't being drawn.
My goal is to have the default icon drawn on first load, and then update it when it changes
Im not getting any 404 or errors in the console, and I've checked my event handlers and they are all working. Can anyone tell me where I've going astray?
Here is what I have so far:
//Initilize the map
google.maps.event.addDomListener(window, 'load', initialize);
function initialize(infowindow) {
var init_center = new google.maps.LatLng(43.703793, -72.326187);
mapOptions = {
center: init_center,
zoom: parseFloat(mapZoomReturn),
mapTypeId: google.maps.MapTypeId.ROADMAP,
scrollwheel : false,
};
var input = document.getElementById('mapAddress');
var autocomplete = new google.maps.places.Autocomplete(input);
var infowindow = new google.maps.InfoWindow();
//var marker = new google.maps.Marker({
// position: init_center,
// map: map,
// icon: mapMarkerImageReturn
//});
// Draw the map
map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
// marker needs to be set after the map
var marker = new google.maps.Marker({
position: init_center,
map: map,
icon: mapMarkerImageReturn
});
// Set up event listeners
// Info window DOM->MAP
google.maps.event.addDomListener(document.getElementById('mapInfoWindow'),
'change', function() {
mapInfoWindowReturn = escape(jQuery('#mapInfoWindow').val());
// get the extra content from feild, by this time the place_changed even will have fired at least once, so we have these values
infowindowPlace = get_info_bubble(locIcon, locName, locAddress, locPhone, locWeb, mapInfoWindowReturn); // returns formatted markup for info bubble
infowindow.setContent(infowindowPlace);
});
// Marker dropdown selection DOM->MAP
google.maps.event.addDomListener(document.getElementById('mapMarker'), 'change', update_maker);
// Custom marker text field DOM->MAP
google.maps.event.addDomListener(document.getElementById('mapMarkerImage'), 'change', update_maker );
function update_maker(){
//update the marker imge - (not working)
markerImage = get_marker_image(); // returns URL as string
marker.setIcon(markerImage);
marker.setPosition(locPlace.geometry.location);
marker.setMap(map);
}
google.maps.event.addListener(autocomplete, 'place_changed', function() {
infowindowPlace = get_info_bubble(locIcon, locName, locAddress, locPhone, locWeb, mapInfoWindowReturn);
infowindow.close();
if (mapMarkerImageReturn !=='' || mapMarkerImageReturn !== false) marker.setVisible(false);
input.className = '';
locPlace = autocomplete.getPlace();
if (!locPlace.geometry) {
// Inform the user that the place was not found and return.
input.className = 'notfound';
return;
}
// If the place has a geometry, then present it on a map.
if (locPlace.geometry.viewport) {
map.fitBounds(locPlace.geometry.viewport);
mapCurrCenter = map.getCenter();
} else {
map.setCenter(locPlace.geometry.location);
map.setZoom(parseFloat(mapZoomReturn));
mapCurrCenter = map.getCenter();
}
// Set the marker image (not working)
markerImage = get_marker_image(); // returns URL as string
marker.setIcon(markerImage);
marker.setPosition(locPlace.geometry.location);
marker.setMap(map);
// get the location values for the info bubble
if (locPlace.address_components) {
//console.log(locPlace.address_components);
// Populate values for info bubble
locName = locPlace.name;
locIcon = locPlace.icon;
locAddress = locPlace.formatted_address;
locPhone = locPlace.formatted_phone_number;
locWeb = locPlace.website;
}
infowindowPlace = get_info_bubble(locIcon, locName, locAddress, locPhone, locWeb, mapInfoWindowReturn);
infowindow.setContent(infowindowPlace);
infowindow.open(map, marker);
});

Google Map markers - add a custom icon with a unique label for each marker

I have implemented a google map with multiple markers but what i am failing to do is how to add a unique label for each marker i.e. Each marker needs have a letter:e.g.
Marker 1 needs to display 'A'
Marker 2 needs to display 'B'
Marker 3 needs to display 'C'
Marker 4 needs to display 'D'
...
an example of what i am trying to achieve is: http://www.athenos.com/locator/ --- enter 11205 in the zip search
here is a portion of my map code - my init and add_marker methods:
init : function() {
var self = this;
// set map property
var map = new google.maps.Map(self.dom_element, self.options);
self.map = map;
// set some other shit
new google.maps.Size(95, 77),
new google.maps.Point(0,0),
new google.maps.Point(47, 76);
// creating new bounds
var bounds = new google.maps.LatLngBounds();
// for loop to iterate through locations
for (var i = 0; i < self.locations.length; i++) {
// extend the bounds
bounds.extend(self.locations[i].latlng);
// add the marker
self.add_marker(self.locations[i].latlng, i);
}
// centers the map based on the existing map markers
self.map.fitBounds(bounds);
},
add_marker : function(latlng, marker_index) {
var self = this;
var marker = new google.maps.Marker({
position: latlng,
map: self.map,
icon: self.map_icon,
zIndex: 998,
id: marker_index // give the marker an ID e.g. 0, 1, 2, 3 - use this for indexing the listed venues
});
google.maps.event.addListener(marker, 'mouseover', function(event) {
var this_marker = this;
// executes handler and passes the marker as 'this' and event data as an argument
self.handle_marker_mouseover.call(self, this, event);
this_marker.setZIndex(999);
});
google.maps.event.addListener(marker, 'mouseout', function(event) {
// executes handler and passes the marker as 'this' and event data as an argument
self.handle_marker_mouseout.call(self, this, event);
});
google.maps.event.addListener(marker, 'click', function(event) {
// executes handler and passes the marker as 'this' and event data as an argument
self.handle_marker_click.call(self, this, event);
});
},
...
Please help.
Thanks in advance

just try to locate your icon, in marker's prop, at this url:
http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=7|00FF00|000000
So iterate with letters over the first part of the chld querystring parameter, and don't forget to choose your marker's color (latest two part, pipe separated)

Take a look at the article below. It's very simple. Use a marker with numeric labels or a marker with alphabet label (A,B..)
Multiple marker with labels in google map
for (i = 1; i <= markers.length; i++) {
var letter = String.fromCharCode("A".charCodeAt(0) + i - 1);
var data = markers[i - 1]
var myLatlng = new google.maps.LatLng(data.lat, data.lng);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.title,
icon: "http://maps.google.com/mapfiles/marker" + letter + ".png"
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.description);
infoWindow.open(map, marker);
});
})(marker, data);
}

reopen infowindow after it's closed in Google map

I have a map with streetview panorama, an infowindow and a draggable marker. After the marker is dragged, a function requests the getPanoramaByLocation to see whether the view service is available. If it's not, it closes the infowindow. That is great but when I click again on the marker the infowindow does not open anymore. Do you know what is wrong please?
tx
var sv = new google.maps.StreetViewService();
function initialize() {
var optionMap = {
zoom: 13,
center: new google.maps.LatLng(47.390251,0.68882),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var myMap = new google.maps.Map(document.getElementById("mapDiv"), optionMap);
var optionsMarker = {
position: new google.maps.LatLng(47.390251,0.68882),
map: myMap,
draggable: true,
title: "my marker"
}
var marker = new google.maps.Marker(optionsMarker);
var infowindowDiv = '<div id="streetview" style="width:300px;height:200px;"' +'</div>';
var infoWindow = new google.maps.InfoWindow({
content: infowindowDiv,
position: myMap.getCenter() });
google.maps.event.addListener(marker, 'click', function() {
infoWindow.open(myMap, marker);
});
google.maps.event.addListener(infoWindow, 'domready', function() {
var panorama = new
google.maps.StreetViewPanorama(document.getElementById("streetview"));
panorama.setPosition(infoWindow.getPosition());
google.maps.event.addListener(marker, 'dragend', function(event) {
sv.getPanoramaByLocation(event.latLng, 50, processSVData);});
function processSVData(data, status) {
if (status == google.maps.StreetViewStatus.OK) {
var markerPanoID = data.location.pano;
// Set the Pano to use the passed panoID
panorama.setPano(markerPanoID);
panorama.setPov({
heading: 270,
pitch: 0,
zoom: 1
});
panorama.setVisible(true);
}
else {
infoWindow.close();
infoWindow = null;
};
}
});
}

From the GMaps API docs:
close() None Closes this InfoWindow by removing it from the DOM structure.
https://developers.google.com/maps/documentation/javascript/reference#InfoWindow
So... If you close the infowindow, it's gone. For ever. All the more so if you REALLY make sure it's gone by saying "infoWindow = null;" You have to make a new one. My advice would be to refactor your code to have a separate function that creates the infowindow on demand and returns it. In your click event definition, check whether infowindow is null, and if so, grab a new one.
HTH

As the other answer explain, the infobox html is removed from DOM when the user clicks the close button, but the JS object still there.
When you create an infowindow you must call the open method to see it on the map
myInfoWindow.open(mymap);
So, if you listen to the 'closeclick' event and keep the infowindow state
var infoWindowClosed = false;
google.maps.event.addListener(myInfoBox, "closeclick", function () {
infoWindowClosed = true;
});
you can reopen myInfoWindow on demand
if(infoWindowClosed){
myInfoWindow.open(mymap);
}

Disable double left click on google map

May I know how can I disable double click on google map so that the info window will not close when I double click on google map? Can it be done through google map api?

You can disable double-click zoom on Google Maps by setting the following google.maps.MapOptions object property:
disableDoubleClickZoom: true
Sample code:
var mapOptions = {
scrollwheel: false,
disableDoubleClickZoom: true, // <---
panControl: false,
streetViewControl: false,
center: defaultMapCenter
};

You can take advantage of, dblclick fires if it is a double click, and single click fires in such occations only once.
runIfNotDblClick = function(fun){
if(singleClick){
whateverurfunctionis();
}
};
clearSingleClick = function(fun){
singleClick = false;
};
singleClick = false;
google.maps.event.addListener(map, 'click', function(event) {// duh! :-( google map zoom on double click!
singleClick = true;
setTimeout("runIfNotDblClick()", 500);
});
google.maps.event.addListener(map, 'dblclick', function(event) {// duh! :-( google map zoom on double click!
clearSingleClick();
});
See http://www.ilikeplaces.com

You need an external var to do that :
var isDblClick;
google.maps.event.addListener(map, 'dblclick', function (event) {
isDblClick = true;
myDlbClickBelovedFunction();
});
google.maps.event.addListener(map, 'click', function (event) {
setTimeout("mySingleClickBelovedFunction();;", 200);
});
function mySingleClickBelovedFunction() {
if (!isDblClick) {
// DO MY SINGLE CLICK BUSINESS :)
}
// DO NOTHING
}

(Please consider that this is not answer, it is only same solution like Ravindranath Akila has been answering already, for using in wider ranges of solutions [eg. Mobile platforms] concentrated on one reusable method without global variables)
We have similar trouble by Win 8.1 Mobile app. Thanks to Ravindranath Akila we finalized solution which is defined in one method and checking also zooming and moving with center of map. Anyway sometimes happened that the address we get from map-click is wrong - improvements are welcomed.
// code
{
// adding event method
addGoogleClickEnventHandler(map, function(e) {
// example code inside click event
var clickLocation = e.latLng;
getAddress(clickLocation);
});
}
// function
function addGoogleClickEnventHandler(googleEventableObject, handlingFunction) {
var boundsChanged = false;
var centerChanged = false;
var singleClick = false;
function runIfNotDblClick(obj) {
if(singleClick && !boundsChanged && !centerChanged){
handlingFunction(obj);
}
};
googleEventableObject.addListener('bounds_changed', function () { boundsChanged = true; });
googleEventableObject.addListener('center_changed', function () { centerChanged = true; });
googleEventableObject.addListener('dblclick', function () { singleClick = false; });
googleEventableObject.addListener('click', function(obj) {
singleClick = true;
setTimeout(function() {
runIfNotDblClick(obj);
}, 200);
boundsChanged = false;
centerChanged = false;
});
}

Here's an example that gives a live preview of the coordinates.
When you click once, it saves the cordinates and when you double click it puts a marker.

You can disable the marker's 'dblClick' event.
event.stopPropagation();
https://developer.mozilla.org/en-US/docs/Web/API/Event/stopPropagation

It cannot be done, you would essentially have to block or prevent the event from happening.
You could try something like createInterceptor() like in EXT JS. This would fire before the event is fired, and you can return false to prevent the actual event to fire, but I am not sure it will prevent the code from executing before the event is fired within that code.
