gmaps.js module to draw custom overlays.
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.
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.
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. By default is not required, since GMaps handles it automatically.
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.
Remove all the overlays from the map and clear the overlays property.
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 |
The following layers are available, and are enumerated in the order in which they are stacked from bottom to top:
| Layer | Description | Order |
|---|---|---|
mapPane |
The lowest pane and is above the tiles. It may not receive DOM events | 0 |
overlayLayer |
Contains polylines, polygons, ground overlays and tile layer overlays. It may not receive DOM events | 1 |
overlayShadow |
Contains the marker shadows. It may not receive DOM events | 2 |
markerLayer |
Contains markers. It may not receive DOM events | 3 |
overlayImage |
Contains the marker foreground images | 4 |
floatShadow |
Contains the info window shadow. It is above the overlayImage, so that markers can be in the shadow of the info window | 5 |
overlayMouseTarget |
Contains elements that receive DOM mouse events, such as the transparent targets for markers. It is above the floatShadow, so that markers in the shadow of the info window can be clickable |
6 |
floatPane |
Contains the info window. It is above all map overlays | 7 |
The reference indicates 5 layers, but the Custom Overlays guide describes 7 layers. Although all the listed layers are present in the code, it seems to be that markerLayer has been splitted in 2 layers: overlayShadow and overlayImage.
