gmaps.overlays
gmaps.js module to draw custom overlays.
Install
For using with bundlers (as Browserify or Webpack):
npm install gmaps.overlays --save
Before require() this module you need to require('gmaps.core').
For using directly in the browser, download the gmaps.overlays.js (or gmaps.overlays.min.js) in dist.
Usage
You need to register a <script> tag with the Google Maps JavaScript API, then import gmaps.core.
Every Google Maps map needs a container (<div id="map"></div> in this demo), which needs to have width and height, and be visible (without display: none, for example):
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script src="http://maps.google.com/maps/api/js?sensor=true"></script>
<script src="gmaps.core.js"></script>
<script src="gmaps.overlays.js"></script>
<style type="text/css">
#map {
width: 400px;
height: 400px;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
var map = new GMaps({
el : '#map',
lat: -12.0433,
lng: -77.0283,
zoom: 12
});
map.drawOverlay({
lat: map.getCenter().lat(),
lng: map.getCenter().lng(),
layer: 'overlayLayer',
content: '<div class="overlay">Lima</div>'
});
</script>
</body>
</html>For more examples you can check the tests in this repo.
Documentation
drawOverlay(options)
Creates a custom overlay using HTML, adds it to the map and returns it.
The options object should contain:
lat(number): The latitude of the position of the overlay in the map.lng(number): The longitude of the position of the overlay in the map.autoShow(boolean): Define if the overlay will be visible at the moment of being added to the map (by default istrue).layer(string): The layer when the overlay will be added. There are 8 layers in Google Maps, which are stacked (See Layers section).content(string or HTML element): The overlay's content. It can be text, HTML string or HTML element.click(function): A callback called every time the overlay is clicked. If this callback is setted, the overlay will be placed in theoverlayMouseTargetlayer.verticalAlign(string): The overlay's vertical position according the coordinate in the map (defined bylatandlng). It can betop,bottomormiddle(by default).horizontalAlign(string): The overlay's horizontal position according the coordinate in the map (defined bylatandlng). It can beleft,rightorcenter(by default).verticalOffset(number): The offset in pixels, in reference to theverticalAlign.horizontalOffset(number): The offset in pixels, in reference to thehorizontalAlign.show(function): A custom function used to show the overlay ifautoShowisfalse.remove(function): A custom function used to remove the overlay.

removeOverlay(overlay)
Removes a overlay from the map and the overlays property. The overlay parameter must be a overlay created with drawOverlay() or one of the elements inside the overlays property.
removeOverlays()
Remove all the overlays from the map and clear the overlays property.
Events
The following methods trigger custom events. You need to add the gmaps.events module before using this module to work with those events:
| Method | Event |
| ------ | ----- |
| drawOverlay | overlay_added |
| removeOverlay | overlay_removed |
| removeOverlays | overlay_removed |
Layers
The following layers are available, and are enumerated in the order in which they are stacked from bottom to top:
| Layer | Order |
| ------ | ----- |
| mapPane | 0 |
| overlayLayer | 1 |
| overlayShadow | 2 |
| markerLayer | 3 |
| overlayImage | 4 |
| floatShadow | 5 |
| overlayMouseTarget | 6 |
| floatPane | 7 |
