谷歌地图JS API V3单一标志物多圈

Question

以上的结果是由多个标记在同一地点交付（不同半径）。

我想一次拖动一个标记，而不是多个标记。

其次，infowindow可用于不同的半径。

任何帮助，非常感谢！

var locations = [ 
    ['US gov suggested', 1.8833, 102.7833, 5, 'green', 80000], 
    ['agricultural contamination', 1.8833, 102.7833, 4, 'blue', 60000], 
    ['Chernobyl_Exclusion_Zone (fallout)', 1.8833, 102.7833, 3, 'yellow', 30000], 
    ['Fukushima evacuation zone', 1.8833, 102.7833, 2, 'red', 20000], 
    ['emergency zone', 1.8833, 102.7833, 1, 'black', 5000] 

]; 

和

var infowindow = new google.maps.InfoWindow(); 

var marker, i; 

for (i = 0; i < locations.length; i++) { 
    marker = new google.maps.Marker({ 
    position: new google.maps.LatLng(locations[i][1], locations[i][2]), 
    draggable: true, 
    map: map 
    }); 

    google.maps.event.addListener(marker, 'click', (function(marker, i) { 
    return function() { 
     infowindow.setContent(locations[i][0]); 
     infowindow.open(map, marker); 
    } 
    })(marker, i)); 

var circle = new google.maps.Circle({ 
     map: map, 
     fillColor:locations[i][4], 
     //fillOpacity:0.3, 
     //strokeColor:locations[i][4], 
     strokeOpacity:0.1, 
     //strokeWeight:1, 
     radius: locations[i][5] // 30 km 
}); 

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

}

Answer 1

只要你想创建尽可能多的圈，利用该方法圆的bindTo()

Answer 2

var infowindow = new google.maps.InfoWindow() 

var marker, i; 
    marker = new google.maps.Marker({ 
    position: new google.maps.LatLng(locations[0][1], locations[0][2]), 
    draggable: true, 
    map: map 
    }); 

for (i = 0; i < locations.length; i++) { 

    var circle = new google.maps.Circle({ 
    map: map, 
    clickable:true, 
    fillColor:locations[i][4], 
    //fillOpacity:0.3, 
    //strokeColor:locations[i][4], 
    strokeOpacity:0.1, 
    //strokeWeight:1, 
    radius: locations[i][5] // 30 km 
    }); 

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

其次结合每个圆圈的position -property标记的center - 属性，它不容易为多个圈子叠加添加infowindow。任何想法或提示？例如，http://img443.imageshack.us/img443/8198/overlap.jpg
