在此代码中我可以将标记更改为我的特定图像，谢谢

您需要执行IF语句来确定标记应加载的图像。

if(i == 0) iconImage = "image1.jpeg";
else if(i == 1)  iconImage = "image2.jpeg";

然后只需将自定义图标和变量添加到标记：

marker = new google.maps.Marker({
          map:map,
          draggable:true,
          animation: google.maps.Animation.DROP,
          position: a[i],
          icon: iconImage
});

在Google Maps API上将默认标记更改为特定图像
