I am having a Google Map with lots of markers added using websockets. I am using custom marker images based on data availability. I want to make sure the newest marker stays on top of all other elements in the map.
How do I do this?
Code:
circleIcon = {
path: google.maps.SymbolPath.CIRCLE,
fillColor: "blue",
fillOpacity: 1,
scale: 2,
strokeColor: "red",
strokeWeight: 10
};
coordinates = image[2].split(',');
pin=new google.maps.LatLng(coordinates[0], coordinates[1]);
if(marker) {
marker.setMap(null);
}
if(image[0] != "NOP") {
var markerIcon = circleIcon;
} else {
var markerIcon = image_car_icon;
}
marker=new google.maps.Marker({
position:pin,
icon:markerIcon
});
marker.setMap(map);
map.setCenter(marker.getPosition());
Update
I am using jquery to update the z-index of the InfoWindow, like:
popup = new google.maps.InfoWindow({
content:'<image id="pin_' + pin_count + '" src="data:image/png;base64,' + image[1] +'"/>',
});
popup.open(map, marker);
google.maps.event.addListener(popup, 'domready', function() {
console.log("DOM READY...........................");
// Bring latest Image to top
e = $('#pin_' + pin_count).parent().parent().parent().parent();
e.css({
'z-index' : 99999 + pin_count,
});
});
Maybe that's why the marker shows behind the InfoWindow. I tried updating using zIndex, but the marker still shows behind the InfoWindow:
marker=new google.maps.Marker({
position:pin,
zIndex: 9999999 + pin_count,
icon:markerIcon
});
Update
Sample code. I expect the "green circle" icon marker to be behind the "pin" icon marker.

A marker identifies a location on a map. By default, a marker uses a standard image. Markers can display custom images, in which case they are usually referred to as "icons." Markers and icons are objects of type Marker .
addListener(myMarker, 'dragend', function(evt){ document. getElementById('current'). innerHTML = '<p>Marker dropped: Current Lat: ' + evt. latLng.
Add different color markerspng at the end of the URL to get a blue marker. To add a green marker simply change it to green-dot.
You have to set the marker option "optimized" to false in combination with the zIndex option.
var marker=new google.maps.Marker({ position:pin2, optimized: false, zIndex:99999999 }); This should solve your problem.

By default map will make z-index higher for markers lower on the map so they visibly stack top to bottom
You can set zIndex option for a marker. You would just need to create a increment zIndex counter as you add markers and add that to the marker options object:
marker=new google.maps.Marker({
position:pin,
icon:markerIcon,
zIndex: counterValue
});
I'm not quite sure what the base start value needs to be
