问(1): 地址 1-5 可以有绿色 pin/marker 而地址 6-60 可以保持默认的红色 pin/marker 吗？

能够使用

将所有引脚更改为绿色、黄色等

marker = new google.maps.Marker({
  icon: 'http://...'
});

然而这改变了所有而不是 select 少数（pins/markers）。

Answer 1

在 Google Maps API v3 中，您可以利用 google.maps.Marker class 的 setIcon 功能来设置标记图标。

例子

var locations = [
     ['Interfaith Medical Center', 40.67836, -73.937781, 1],
     ['Kingsbrook Jewish Medical Center', 40.65935, -73.933232, 2],
     ['Kingsboro Psychiatric Center', 40.656192, -73.937523, 3],
     ['Kings County Hospital Center', 40.657201, -73.944647, 4],
     ['University Hospital of Brooklyn', 40.655378, -73.945763, 5],
     ['New York Methodist Hospital', 40.667098, -73.978336, 6],
     ['Brookdale University Hospital and Medical Center', 40.655411, -73.912418, 7],
     ['Wyckoff Heights Medical Center', 40.704148, -73.917607, 8],
     ['Woodhull Medical Center', 40.698731, -73.942759, 9],
     ['The Brooklyn Hospital Center', 40.690206, -73.97825, 10]
];

var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 12,
    center: new google.maps.LatLng(40.67836, -73.937781),
    mapTypeId: google.maps.MapTypeId.ROADMAP
});

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]),
        map: map
    });

    if (i < 5) {  //set marker icon to green for the first 5 markers
        marker.setIcon('http://maps.google.com/mapfiles/ms/icons/green-dot.png');
    }

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