Adding custom marker text to Google Map

问题:

I'm creating a new website for new law office.

I followed Google API for embedding maps. I added their address, but would like to add the name of the firm to the map... You can see in the map, it doesn't capture the name:

<iframe width="600" height="450" frameborder="0" style="border:0" src="https://www.google.com/maps/embed/v1/place?key=myapikey&q=883%20Farmington%20Avenue%2C%20Berlin%2C%20CT%2006037%2C%20United%20States"></iframe>

So, I tried adding a name before the address in the iframe:

q=Jill+Levin+Law,address here...

But I'm guessing the keyword Levin pick ups a matching firm, Soulsby & Levin, LLC... even though I haven't changed the address 

<iframe width="600" height="450" frameborder="0" style="border:0" src="https://www.google.com/maps/embed/v1/place?key=myapikey&q=Jill+Levin+Law,883%20Farmington%20Avenue%2C%20Berlin%2C%20CT%2006037%2C%20United%20States"></iframe>

Even the Google API itself picks up the wrong one based on the keyword:

How do I:

  • Have Google map pick up the correct name of the office
  • If the office name hasn't been defined yet, how can I simply add the text name to the top of the marker?

回答1:

When you add the marker to the map you can put a title to the marker.

Use this code to do it:

map.addMarker(new MarkerOptions().title("Office Name"));


回答2:

Yo can set the Latitude and Longitude of your marker and include a Title on it.

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(-25.363882,131.044922),
    map: map,
    title: 'Our Office'
});

I have the lively sample for this 

var map;
var root;
var geocoder;
var root_content= 'Type: [type]<BR>IP: 192.168.10.25<BR>Address: [address]';
function initialize() {
    geocoder = new google.maps.Geocoder();
        geocoder.geocode( { 'address': 'Ha noi, Vietnam'}, function(results, status) {
				root = results[0].geometry.location;
			
			var myStyles =[
			
       {
         featureType: "administrative",
         elementType: "labels",
         stylers: [
           { visibility: "off" }
         ]
       },{
         featureType: "poi",
         elementType: "labels",
         stylers: [
           { visibility: "off" }
         ]
       },{
         featureType: "water",
         elementType: "labels",
         stylers: [
           { visibility: "off" }
         ]
       }
     
];
				map = new google.maps.Map(document.getElementById('map'), {
				  zoom: 10,
				  center: root,

  map.controls[google.maps.ControlPosition.TOP_LEFT].push(zoomControlDiv);
