我已设法在谷歌地图上使用并应用我自己的标记,如下所示。
var marker = new google.maps.Marker({
position: point,
map: map,
icon: pIcon,
optimized:false
});
我想在下面添加一个圆角背景,如下面的css
#orangeIcon {
width: 50px;
height: 50px;
overflow: hidden;
border-top-left-radius:5px 5px;
border-top-right-radius:5px 5px;
border-bottom-left-radius:5px 5px;
border-bottom-right-radius:5px 5px;
-moz-box-shadow: 0 1px 3px #FFBF00;
-webkit-box-shadow: 0 1px 3px #FFBF00;
background-color: #FFBF00;
position: relative;
border: 5px solid #FFBF00;
}
如何为谷歌地图实现这一目标?

从版本3.17开始,google.maps.Marker对象存在于markerLayer
pane中,这只是div的一个奇特名称。
要获取对markerLayer的引用,您需要创建一个OverlayView对象。现在,这个对象有点抽象。您需要实现绘图功能才能工作。例如,在新标签页中打开basic example并将其粘贴到控制台
var overlay = new google.maps.OverlayView();
overlay.draw=function() {};
overlay.setMap(map);
overlay.getPanes();
它返回:
{
floatPane: div
floatShadow: div
mapPane: div
markerLayer: div
overlayImage: div
overlayLayer: div
overlayMouseTarget: div
overlayShadow: div
}
Thay markerLayer是一个包含标记的div。如果我使用给定的图标图像创建标记,
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
icon: 'http://ruralshores.com/assets/marker-icon.png',
optimized:false
});
我的markerLayer将是:
所选div(具有z-index 103的div)是markerLayer。
如果您想以编程方式访问markerLayer,可以添加" markerLayer"使用getPanes
方法获取其引用后的类。我想markerLayer中的每个图像都是一个标记,所以你可以随意设置它。
TL / DR :您可以设置样式,前提是您在查找标记的DOM引用时遇到了所有麻烦。

当您知道用于标记的图像的网址时,您知道如何通过CSS访问它:使用属性选择器。
让我们根据您的头像创建一个圆形标记,并带有1px黑色边框:
分子标记设置:
icon:{
url: 'https://www.gravatar.com/avatar/0a9745ea7ac5c90d7acadb02ab1020cd?s=32&d=identicon&r=PG&f=1',
//the size of the image is 32x32,
//when you want to add a border you must add 2*borderWidth to the size
size:new google.maps.Size(34,34)},
//define the shape
shape:{coords:[17,17,18],type:'circle'},
//set optimized to false otherwise the marker will be rendered via canvas
//and is not accessible via CSS
optimized:false
}
CSS:
img[src="https://www.gravatar.com/avatar/0a9745ea7ac5c90d7acadb02ab1020cd?s=32&d=identicon&r=PG&f=1"]{
border-radius:16px;
border:1px solid #000 !important;
}
....完成。

您好我尝试了所有这些答案,但没有人像我想的那样工作 首先尝试创建一个div包含图像(MarkerImage)并添加CSS
var map;
function initialize() {
var mapOptions = {
zoom: 9,
center: new google.maps.LatLng(40.6, -74)
};
map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
// I create 3 markers using http://ruralshores.com/assets/marker-icon.png as icon
var myIcon='http://ruralshores.com/assets/marker-icon.png';
var marker1 = new google.maps.Marker({ position: {lat:40.8, lng:-74}, map: map, icon: myIcon, optimized:false });
var marker2 = new google.maps.Marker({ position: {lat:40.6, lng:-74.5}, map: map, icon: myIcon , optimized:false });
var marker3 = new google.maps.Marker({ position: {lat:40.5, lng:-74.3}, map: map, icon: myIcon , optimized:false });
// I create an OverlayView, and set it to add the "markerLayer" class to the markerLayer DIV
var myoverlay = new google.maps.OverlayView();
myoverlay.draw = function () {
this.getPanes().markerLayer.id='markerLayer';
};
myoverlay.setMap(map);
}
google.maps.event.addDomListener(window, 'load', initialize);
现在添加somme CSS
#markerLayer img {
border: 2px solid red !important;
width: 85% !important;
height: 90% !important;
border-radius: 5px;
}

如上所述,我使用了OverlayView
var AvatarMarker = function(latlng,avatarUrl,map,id){
this.latlng = latlng;
this.avatarUrl = avatarUrl;
this.setMap(map);
this.id= id;
};
AvatarMarker.prototype = new google.maps.OverlayView();
AvatarMarker.prototype.onAdd= function(){
var img = document.createElement("img"),me=this;
img.style.width="30px";
img.style.height="30px";
img.style.position="absolute";
img.style.webkitBorderRadius="50%";
img.style.borderRadius="50%";
img.style.zIndex="999";
img.src=me.avatarUrl;
this.getPanes().overlayMouseTarget.appendChild(img);
me.img= img;
img.onclick = function(){
google.maps.event.trigger(me,"click",{id:me.id});
}
};
AvatarMarker.prototype.draw = function(){
this.setLatLng(this.latlng);
}
AvatarMarker.prototype.onRemove = function(){
this.img.parentNode.removeChild(this.img);
this.img = null;
}
AvatarMarker.prototype.setLatLng = function(latlng){
if(!this.getProjection()) return ;
var overlayProjection = this.getProjection(),
xy=overlayProjection.fromLatLngToDivPixel(latlng);
this.img && (this.img.style.left=(xy.x-15)+'px');
this.img && (this.img.style.top=(xy.y-15)+'px');
google.maps.event.trigger(this,"draw");
}
AvatarMarker.prototype.getLatLng = function(){return this.latlng;}
