Custom icon for Google Maps Marker

Question

Following code working:

function()
    {
    var Marker = new google.maps.Marker();
    var MarkerOptions = {};
    MarkerOptions.map = my_map;
    MarkerOptions.position = new google.maps.LatLng(0,0);
    MarkerOptions.animation = google.maps.Animation.DROP;
    MarkerOptions.clickable = true;
    MarkerOptions.cursor = 'pointer';

    Marker.smallicon = [{
        anchor:null,
        origin:null,
        scaledSize:null,
        size:new google.maps.Size(20,32),
        url:'http://maps.gstatic.com/mapfiles/markers2/marker_sprite.png'
        }];

    Marker.setOptions(MarkerOptions);
    }

And after add this one line, console shooting full of errors

function()
    {
    var Marker = new google.maps.Marker();
    var MarkerOptions = {};
    MarkerOptions.map = way_map;
    MarkerOptions.position = new google.maps.LatLng(0,0);
    MarkerOptions.animation = google.maps.Animation.DROP;
    MarkerOptions.clickable = true;
    MarkerOptions.cursor = 'pointer';

    Marker.smallicon = [{
        anchor:null,
        origin:null,
        scaledSize:null,
        size:new google.maps.Size(20,32),
        url:'http://maps.gstatic.com/mapfiles/markers2/marker_sprite.png'
        }];

    Marker.setIcon(Marker.smallicon);
    Marker.setOptions(MarkerOptions);
    }

I don't understand it more, it working with google.maps.MarkerImage but in reference is written

A structure representing a Marker icon or shadow image. This class is deprecated in favor of Icon.

So i try to work with Icon, they have changed it from constructor to Object so was changed the model of calling.

I Think This Is Fine For You

//adapted from http://gmaps-samples-v3.googlecode.com/svn/trunk/overlayview/custommarker.html
function CustomMarker(latlng, map, imageSrc) {
    this.latlng_ = latlng;
    this.imageSrc = imageSrc;
    // Once the LatLng and text are set, add the overlay to the map.  This will
    // trigger a call to panes_changed which should in turn call draw.
    this.setMap(map);
}

CustomMarker.prototype = new google.maps.OverlayView();

CustomMarker.prototype.draw = function () {
    // Check if the div has been created.
    var div = this.div_;
    if (!div) {
        // Create a overlay text DIV
        div = this.div_ = document.createElement('div');
        // Create the DIV representing our CustomMarker
        div.className = "customMarker"


        var img = document.createElement("img");
        img.src = this.imageSrc;
        div.appendChild(img);
        google.maps.event.addDomListener(div, "click", function (event) {
            google.maps.event.trigger(me, "click");
        });

        // Then add the overlay to the DOM
        var panes = this.getPanes();
        panes.overlayImage.appendChild(div);
    }

    // Position the overlay 
    var point = this.getProjection().fromLatLngToDivPixel(this.latlng_);
    if (point) {
        div.style.left = point.x + 'px';
        div.style.top = point.y + 'px';
    }
};

CustomMarker.prototype.remove = function () {
    // Check if the overlay was on the map and needs to be removed.
    if (this.div_) {
        this.div_.parentNode.removeChild(this.div_);
        this.div_ = null;
    }
};

CustomMarker.prototype.getPosition = function () {
    return this.latlng_;
};

var map = new google.maps.Map(document.getElementById("map"), {

<div id="map" style="width: 640pxpx; height: 480px;">map div</div>

Answer 2

Marker.smallicon currently is an array, not a google.maps.Icon

use either:

Marker.setIcon(Marker.smallicon[0]);

or let it be an object:

Marker.smallicon = {
        size:new google.maps.Size(20,32),
        url:'http://maps.gstatic.com/mapfiles/markers2/marker_sprite.png'
        };

Note: you don't need to set all options of a google.maps.Icon, ommit the options that you dont want to set.

Answer 3

Use:

icon: {url:'http://maps.gstatic.com/mapfiles/markers2/marker_sprite.png'}

instead of

url:'http://maps.gstatic.com/mapfiles/markers2/marker_sprite.png'
