<p>You can define many overlay map types this way:</p>
|
<pre>var getTile = function(coord, zoom, ownerDocument) {
|
var div = ownerDocument.createElement('div');
|
div.innerHTML = coord;
|
div.style.width = this.tileSize.width + 'px';
|
div.style.height = this.tileSize.height + 'px';
|
div.style.background = 'rgba(250, 250, 250, 0.55)';
|
div.style.fontFamily = 'Monaco, Andale Mono, Courier New, monospace';
|
div.style.fontSize = '10';
|
div.style.fontWeight = 'bolder';
|
div.style.border = 'dotted 1px #aaa';
|
div.style.textAlign = 'center';
|
div.style.lineHeight = this.tileSize.height + 'px';
|
return div;
|
};
|
|
map.addOverlayMapType({
|
index: 0,
|
tileSize: new google.maps.Size(256, 256),
|
getTile: getTile
|
});</pre>
|
<p>You must define a function called <code>getTile</code>, which returns a HTML element used to fill the map overlay. Also, you have to set an overlay <code>index</code>, which place the overlay on top of the base map, according this index.</p>
|
<p><span class="label notice">NOTE:</span> You can remove an overlay map type using <code>removeOverlayMapType(overlay_index)</code>.</p>
