在Google地图标记周围添加圆/半径

Question

任何能够帮助我在我的谷歌地图标记周围添加圆/半径的人？

function createMarker (size, i,id,lat,lng,pin,title,counter,image,price,single_first_type,single_first_action,link,rooms,baths,cleanprice,single_first_type_name, single_first_action_name){ 


    var myLatLng = new google.maps.LatLng(lat,lng); 


    var marker = new google.maps.Marker({ 
     position:   myLatLng, 
     map:    map, 
     icon:    custompin(pin), 
     shape:    shape, 
     title:    title, 
     zIndex:    counter, 
     image:    image, 
     idul:    id, 
     price:    price, 
     category:   single_first_type, 
     action:    single_first_action, 
     link:    link, 
     infoWindowIndex : i, 
     rooms:    rooms, 
     baths:    baths,

添加一个固定半径的圆（比如：100）的标记中的每一个，它只是一个声明一个圆圈，一旦你已经宣布你的标记物：

gmarkers.push(marker); 
bounds.extend(marker.getPosition()); 

marker.Circle = new google.maps.Circle({ 
    center:marker.getPosition(), 
    radius: 100, 
    map: map 
}); 

请注意我已将圆圈附加到标记实例，因此您不需要保留单独的圆形数组来处理它们。

如果您的标记可切换（您想在给定事件后打开/关闭它们），然后将该圆的地图属性绑定到标记的地图上以切换。

marker.Circle.bindTo('map', marker); 

如果你的标记是可拖动的，你想圆围绕跟随其标记，bidn圆的中心标记位置

marker.Circle.bindTo('center', marker, 'position');
