Using Icon Fonts as Markers in Google Maps V3

问题:

I was wondering whether it is possible to use icon font icons (e.g. Font Awesome) as markers in Google Maps V3 to replace the default marker. To show/insert them in a HTML or PHP document the code for the marker would be:

<i class="icon-map-marker"></i>

Here's my attempt at the same thing (using "markerwithlabel" utility library) before I realised Nathan did the same more elegantly above: http://jsfiddle.net/f3xchecf/

function initialize() {

    var myLatLng = new google.maps.LatLng( 50, 50 ),
        myOptions = {
            zoom: 4,
            center: myLatLng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
            },

        map = new google.maps.Map( document.getElementById( 'map-canvas' ), myOptions ),

     marker = new MarkerWithLabel({
       position: myLatLng,
       draggable: true,
       raiseOnDrag: true,
       icon: ' ',
       map: map,
         labelContent: '<i class="fa fa-send fa-3x" style="color:rgba(153,102,102,0.8);"></i>',
       labelAnchor: new google.maps.Point(22, 50)
     });

    marker.setMap( map );
}

initialize();

I just had the same problem - decided to do a quick and dirty conversion and host on github.

You can manually include the JS file, or use npm install fontawesome-markers or bower install fontawesome-markers.

Just include the javascript file fontawesome-markers.min.js and you can use them like so:

new google.maps.Marker({
    map: map,
    icon: {
        path: fontawesome.markers.EXCLAMATION,
        scale: 0.5,
        strokeWeight: 0.2,
        strokeColor: 'black',
        strokeOpacity: 1,
        fillColor: '#f8ae5f',
        fillOpacity: 0.7
    },
    clickable: false,
    position: new google.maps.LatLng(lat, lng)
});

Edit (April-2016): There's now packages for v4.2 -> v4.6.1

I know this is an old post, but just in case you can use the MarkerLabel object now:

var marker = new google.maps.Marker({
    position: location,
    map: map,
    label: {
        fontFamily: 'Fontawesome',
        text: '\uf299'
    }
});

Worked for me.

In a modern browser one can use the canvas in order to render the font to png, and then use the data URI scheme:

  function getIcon(glyph, color) {
    var canvas, ctx;
    canvas = document.createElement('canvas');
    canvas.width = canvas.height = 20;
    ctx = canvas.getContext('2d');
    if (color) {
      ctx.strokeStyle = color;
    }
    ctx.font = '20px FontAwesome';
    ctx.fillText(glyph, 0, 16);
    return canvas.toDataURL();
  }

For example: getIcon("\uf001") for the music note.

The light weight solution

• fontawesome-markers: 480kb
• markerwithlabel: 25kb

To avoid these dependencies, simple go to fontawesome-markers, find the path for the icon you want, and include it as follows:

var icon = {
    path: "M27.648-41.399q0-3.816-2.7-6.516t-6.516-2.7-6.516 2.7-2.7 6.516 2.7 6.516 6.516 2.7 6.516-2.7 2.7-6.516zm9.216 0q0 3.924-1.188 6.444l-13.104 27.864q-.576 1.188-1.71 1.872t-2.43.684-2.43-.684-1.674-1.872l-13.14-27.864q-1.188-2.52-1.188-6.444 0-7.632 5.4-13.032t13.032-5.4 13.032 5.4 5.4 13.032z",
    fillColor: '#E32831',
    fillOpacity: 1,
    strokeWeight: 0,
    scale: 0.65
}

marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    icon: icon
});

I've put together a simple JS library that generates nice SVG markers using the Font Awesome icons. https://github.com/jawj/MapMarkerAwesome

If you want the awesomefont MARKER with an awesomefont ICON INSIDE:

1. copy the SVG path of the awesomefont marker (click download and copy the SVG path) and use it as icon (remember to credit the authors, see license). Then you can change it's color to anything you want.

2. As label you only insert the awesome font icon code and the color you want.
