Google maps Marker Label with multiple characters
You can use MarkerWithLabel with SVG icons.
Update: The Google Maps Javascript API v3 now natively supports multiple characters in the MarkerLabel
proof of concept fiddle (you didn't provide your icon, so I made one up)
Note: there is an issue with labels on overlapping markers that is addressed by this fix, credit to robd who brought it up in the comments.
code snippet:
function initMap() {
var latLng = new google.maps.LatLng(49.47805, -123.84716);
var homeLatLng = new google.maps.LatLng(49.47805, -123.84716);
var map = new google.maps.Map(document.getElementById('map_canvas'), {
zoom: 12,
center: latLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new MarkerWithLabel({
position: homeLatLng,
map: map,
draggable: true,
raiseOnDrag: true,
labelContent: "ABCD",
labelAnchor: new google.maps.Point(15, 65),
labelClass: "labels", // the CSS class for the label
labelInBackground: false,
icon: pinSymbol('red')
});
var iw = new google.maps.InfoWindow({
content: "Home For Sale"
});
google.maps.event.addListener(marker, "click", function(e) {
iw.open(map, this);
});
}
function pinSymbol(color) {
return {
path: 'M 0,0 C -2,-20 -10,-22 -10,-30 A 10,10 0 1,1 10,-30 C 10,-22 2,-20 0,0 z',
fillColor: color,
fillOpacity: 1,
strokeColor: '#000',
strokeWeight: 2,
scale: 2
};
}
google.maps.event.addDomListener(window, 'load', initMap);

First of all, Thanks to code author!
I found the below link while googling and it is very simple and works best. Would never fail unless SVG is deprecated.

There is some js loading error in the code here but its perfectly working on the codepen.io link provided.

You just need to uri-encode your SVG html and replace the one in the image variable after "data:image/svg+xml" in the for loop.
For uri encoding you can use uri-encoder-decoder
You can decode the existing svg code first to get a better understanding of what is written.
OK, here is one solution I have come up with which is pretty messed up.
I put the full label text into the div using the fontFamily label attribute. Then I use querySelectorAll to match the resulting style attributes to pull out the refs and rewrite the tags once the map has loaded:
var label = "A123";
var marker = new google.maps.Marker({
position: latLon,
label: {
text: label,
// Add in the custom label here
fontFamily: 'Roboto, Arial, sans-serif, custom-label-' + label
},
map: map,
icon: {
path: 'custom icon path',
fillColor: '#000000',
labelOrigin: new google.maps.Point(26.5, 20),
anchor: new google.maps.Point(26.5, 43),
scale: 1
}
});
google.maps.event.addListener(map, 'idle', function() {
var labels = document.querySelectorAll("[style*='custom-label']")
for (var i = 0; i < labels.length; i++) {
// Retrieve the custom labels and rewrite the tag content
var matches = labels[i].getAttribute('style').match(/custom-label-(A\d\d\d)/);
labels[i].innerHTML = matches[1];
}
});
This seems pretty brittle. Are there any approaches which are less awful?
