Вы можете использовать InfoWindow и передавать свой div как содержимое Infowindow. Вот образец скрипта и фрагмент кода:
function initMap() {
var uluru = {lat: -25.363, lng: 131.044};
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 4,
center: uluru
});
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+
'<div id="bodyContent">'+
'<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +
'sandstone rock formation in the southern part of the '+
'Northern Territory, central Australia.</p>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString,
position: uluru
});
infowindow.open(map);
}
Вы также можете проверить эту ссылку о том, как рисовать в API Карт JavaScript. Если вы хотите реализовать собственное наложение, вы можете попробовать создать собственное пользовательское наложение , в котором вы создаете div для хранения изображения или вашего контента. Вот образец скрипта и фрагмент кода:
var overlay;
YourOverlay.prototype = new google.maps.OverlayView();
// Initialize the map and the custom overlay.
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 11,
center: {lat: 62.323907, lng: -150.109291},
mapTypeId: 'satellite'
});
var bounds = new google.maps.LatLngBounds(
new google.maps.LatLng(62.281819, -150.287132),
new google.maps.LatLng(62.400471, -150.005608));
// You can put image here, I find some random one from the internet in this sample.
var srcImage = 'https://webstockreview.net/images/neon-border-png.png';
// The custom USGSOverlay object contains the USGS image,
// the bounds of the image, and a reference to the map.
overlay = new YourOverlay(bounds, srcImage, map);
}
/** @constructor */
function YourOverlay(bounds, image, map) {
// Initialize all properties.
this.bounds_ = bounds;
this.image_ = image;
this.map_ = map;
// Define a property to hold the image's div. We'll
// actually create this div upon receipt of the onAdd()
// method so we'll leave it null for now.
this.div_ = null;
// Explicitly call setMap on this overlay.
this.setMap(map);
}
/**
* onAdd is called when the map's panes are ready and the overlay has been
* added to the map.
*/
YourOverlay.prototype.onAdd = function() {
var div = document.createElement('div');
div.style.borderStyle = 'none';
div.style.borderWidth = '0px';
div.style.position = 'absolute';
var statement = document.createElement('p');
statement.style.fontSize = '20px';
statement.style.color = 'white';
var node = document.createTextNode("This is a new paragraph.");
statement.appendChild(node);
div.appendChild(statement);
// Create the img element and attach it to the div.
var img = document.createElement('img');
img.src = this.image_;
img.style.width = '100%';
img.style.height = '100%';
img.style.position = 'absolute';
div.appendChild(img);
this.div_ = div;
// Add the element to the "overlayLayer" pane.
var panes = this.getPanes();
panes.overlayLayer.appendChild(div);
};
YourOverlay.prototype.draw = function() {
// We use the south-west and north-east
// coordinates of the overlay to peg it to the correct position and size.
// To do this, we need to retrieve the projection from the overlay.
var overlayProjection = this.getProjection();
// Retrieve the south-west and north-east coordinates of this overlay
// in LatLngs and convert them to pixel coordinates.
// We'll use these coordinates to resize the div.
var sw = overlayProjection.fromLatLngToDivPixel(this.bounds_.getSouthWest());
var ne = overlayProjection.fromLatLngToDivPixel(this.bounds_.getNorthEast());
// Resize the image's div to fit the indicated dimensions.
var div = this.div_;
div.style.left = sw.x + 'px';
div.style.top = ne.y + 'px';
div.style.width = (ne.x - sw.x) + 'px';
div.style.height = (sw.y - ne.y) + 'px';
};
// The onRemove() method will be called automatically from the API if
// we ever set the overlay's map property to 'null'.
YourOverlay.prototype.onRemove = function() {
this.div_.parentNode.removeChild(this.div_);
this.div_ = null;
};
google.maps.event.addDomListener(window, 'load', initMap);
Надеюсь, это поможет.
