Cannot get a different Icon in Google map on change event - javascript

I am new to Google API V3. I want to change the Icon on Zoom event. The full code is running as expected, it is the last bit wherein I have given a map change event to capture the change in zoom so that I could change in the icon from a simple circle to Google standard red icon. Please do review and suggest corrections, thank you so much.

Here you go...I fixed your code for you...you had a few errors. Biggest one being that you were not saving the markers you created into an array to loop through on the event listener.
I added the gMarkers array. I ran the code in the console of your site and it worked. Let me know if you have any questions.
var infowindow;
var map;
var gMarkers=[];

for (var i = 0; i < markers.length; i++) {

}else{

animated gif in array in google map

I am trying to use optimize:false parameter in my code to use animated gif as a mouseover:
var icon1 = "circle.png";
var icon2 = "circlered.gif";
var markers = [];
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
visible: false,
icon: icon1
});
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
}
})(marker, i));
markers.push(marker); // save all markers
google.maps.event.addListener(marker, 'mouseout', (function(marker) {
return function(evt) {
infowindow.close();
marker.setIcon(icon1);
}
})(marker));
when I use for example:
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
visible: false,
icon: icon2, //here I purposely changed it to animated gif first
optimize: false
});
I have no problems.
but when I try to use the same here:
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
optimize:false;// here is the wrong code obviously
}
})(marker, i));
I get the image disappearing not animating
Please suggest solution

</html>
as you can see the code in "Fir AZE" draws a layer.
then later it(the drawn layer) is supposed to be shown on click , the example provided initially at this link www.visualguide.ca/example shows that.
when I was asking about the solution for the animated marker I thought that I had problem with optimize :false - because all their lines of code were working ok.
as I have tried to implement solution provided below it worked! but I lost my ability to show/hide layers on click.sorry if this was not clear initially
my intial code was:
function initialize() {
var mapOptions = {
zoom: 8,
center: new google.maps.LatLng(40.222869, 47.602673),
mapTypeId: google.maps.MapTypeId.TERRAIN,
zIndex: 3
};
// Set map
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
it was changed to
function initialize() {
var map = new google.maps.Map(
document.getElementById("map-canvas"), {
center: new google.maps.LatLng(40.222869, 47.602673),
zoom: 13,
mapTypeId: google.maps.MapTypeId.TERRAIN
});
var bounds = new google.maps.LatLngBounds();
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
optimized: false,
visible: false,
icon: icon1
});
bounds.extend(marker.getPosition())
//....
}
map.fitBounds(bounds);
}
I have compared line by line to locate this, and am stumbled.
One option is to create the marker with {optimized: false}:
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map,
optimized: false,
icon: icon1
});
google.maps.event.addListener(marker, 'mouseover', (function(marker, i) {
return function(evt) {
infowindow.setContent(locations[i][0] + "<br>" + marker.getPosition().toUrlValue(6));
infowindow.open(map, marker);
marker.setIcon(icon2);
}
})(marker, i));
markers.push(marker); // save all markers
google.maps.event.addListener(marker, 'mouseout', (function(marker) {
return function(evt) {
infowindow.close();
marker.setIcon(icon1);
}
})(marker));
}

google map api V3 markers

I am having a problem with google maps, I cant put markers on some location. My idea was to find my location and to put marker on it, then to put markers on other locations but the markers on other locations are not showing on a map.

The main problem with your function is that your marker adding loop is outside success function, so it never gets called. You also had an extra }at the end of your code. Here is a full solution jsfiddle
var map;
function success(position) {
var mapcanvas = document.createElement('div');
mapcanvas.id = 'mapcontainer';
mapcanvas.style.height = '550px';
mapcanvas.style.width = '960px';
document.querySelector('article').appendChild(mapcanvas);
var coords = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);
var options = {
zoom: 15,
center: coords,
mapTypeControl: false,
navigationControlOptions: {
style: google.maps.NavigationControlStyle.SMALL
},
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("mapcontainer"), options);
var marker = new google.maps.Marker({
position: coords,
map: map,

navigator.geolocation.getCurrentPosition(success);

success(position);
the main problem with your code is you are plotting the marker before the map is loaded because it is out side of your function success.try this:I have use static value for center you can change it as per your code.
$(document).ready(function () {
success(position);
});
var position = { // suppose this is your position

Custom Marker Overlap issue

I have displayed custom markers on the map. Some of them are overlapped each other.
so, for that i have created one logic to display infowindows seperate on each marker click.
Here is my Example : http://jsfiddle.net/u758rqpa/20/
Here you can see that when click on marker map is zooming.
but , i want that when i clicked on overlapped marker then it should be zoom not on one seperate marker click.
so, is there any way to find out that the markers are overlapped ?
so, i can stop zooming when marker is seperate.
google.maps.event.addListener(marker, 'click', (function (marker, x, content) {
return function () {
var zoomLevel = map.getZoom();
if (zoomLevel != 15)
map.setZoom(zoomLevel + 1)
infowindow.close();
infowindow.setOptions({
content: content,
pixelOffset: new google.maps.Size(0, 20)
})
infowindow.open(map, this);
}
})(marker, x, content));
There is easy way for this, Marker Clusterer

mapData is a JSON response which brings 'Latitude','Longitude','Speed','State','Location' values.
I have drawn polylines for the Lats and Longs , but the markers are not displayed.And getting this error
TypeError: f is undefined
Your design is not clear to me exactly.
If you want to get marker visible in mouseout event listener than you have to provide map value. For example:
var marker = new google.maps.Marker({
position: event.latLng,
map: map
});
In that case you have to make map global. Currently it is locally defined in function initialize(). So:
var map;
function initialize(flightPlanCoordinates_arr) {
...
map = new google.maps.Map(document.getElementById('map'), mapOptions);
...
}
Additionally, it seems that this for loop
for (var i = 0; i < flightPlanCoordinates.length; i++) {
should be initialized as:
for (var i = 0; i < flightPlanCoordinates.length - 1; i++) {
Update: see example at jsbin. It's best I can get because I do not understand whole logic of some variables checking. If you set prober icon marker will be set. Note: I cannot perform that ajax call so I had to model data.

Google Maps marker event listener is not working

Here is a link to my test example and the code which I am trying to figure out.
http://www.gaiser-vfx.com/media/maptest.html
<div id="googleMap">
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script type="text/javascript" src="http://code.google.com/apis/gears/gears_init.js"></script>
<div id="map_canvas" style="width:100%; height:300px"></div>
<script>
var noLocation = new google.maps.LatLng(52.1307, -3.78371);
var initialLocation;
var browserSupportFlag = new Boolean();
var map;
var myOptions = {
zoom: 6,
draggable: true,
minZoom: 0,
maxZoom: 20,
disableDefaultUI: true,
zoomControl: true,
scrollwheel: true,
disableDoubleClickZoom: true,
mapTypeId: google.maps.MapTypeId.false
};
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'bounds_changed', function() {
var center = map.getCenter();
var zoomLevel = map.getZoom();
$('#LocationLatitude').val(center.lat().toFixed(5));$('#LocationLongitude').val(center.lng().toFixed(5));$('#LocationZoom').val(zoomLevel);});
var poly
var path = new google.maps.MVCArray;
poly = new google.maps.Polygon({
strokeWeight: 3,
fillColor: '#5555FF'
});
poly.setMap(map);
poly.setPaths(new google.maps.MVCArray([path]));
google.maps.event.addListener(map, 'click', addPoint);
function addPoint(event) {
path.insertAt(path.length, event.latLng);
var marker = new google.maps.Marker({
position: event.latLng,
map: map,
draggable: true
});
markers.push(marker);
marker.setTitle("#" + path.length);
google.maps.event.addListener(marker, 'click', function() {
marker.setMap(null);
for (var i = 0, I = markers.length; i < I && markers[i] != marker; ++i);
markers.splice(i, 1);
path.removeAt(i);
});
google.maps.event.addListener(marker, 'dragend', function() {
for (var i = 0, I = markers.length; i < I && markers[i] != marker; ++i);
path.setAt(i, marker.getPosition());
}
);
}
</script>
`
This is the example I am trying to follow.
http://gmaps-samples-v3.googlecode.com/svn/trunk/poly/poly_edit.html
One of the main differences between my code and the example is the use of an initialize function call in the example while I am just trying to load mine when it loads the page. On my map test, I am able to place markers on the map and pick them up and move them, but the function on each marker that updates the poly to the new marker point and the ability to delete each marker does not seem to work.
It looks like all you have to do is declare a markers variable visible to the event listeners:
...
var markers = [];
var poly;
var path = new google.maps.MVCArray;
...
