tag

Each item created can be accessed or identified on events thanks to tags.

tag

Tag can be

• string
• array of string
• a function which return an array of string

In this example, marker are automatically generated with 2 tags (letter / color) and then, some of them are removed.

var colors = "black brown green purple yellow grey orange white".split(" "),
  letters = "A B C D E F".split(" ");

$("#test").gmap3({
  map:{
    options:{
      zoom: 2,
      mapTypeId: google.maps.MapTypeId.TERRAIN
    },
    onces: {
      bounds_changed: function(){
        var $this = $(this),
          bounds = $this.gmap3("get").getBounds(),
          southWest = bounds.getSouthWest(),
          northEast = bounds.getNorthEast(),
          lngSpan = northEast.lng() - southWest.lng(),
          latSpan = northEast.lat() - southWest.lat(),
          i, color, letter;
      	for (i = 0; i < 50; i++) {
          letter = letters[Math.floor(Math.random() * letters.length)];
          color = colors[Math.floor(Math.random() * colors.length)];
      	 
          $this.gmap3({
            marker:{
              latLng:[southWest.lat() + latSpan * Math.random(), southWest.lng() + lngSpan * Math.random()],
              options:{
                icon: "http://maps.google.com/mapfiles/marker_"+color+letter+".png"
              },
              tag:[color, letter]
            }
          });
        }
      }
    }
  }
});
