这段代码的作用是,当用户输入两个坐标时,它用两个标记和一条显示方向的线来设置地图。是否可以将d*错误标记*更改为特定图像不同地用于两个坐标,假设我希望第一个坐标表示"image1.jpeg",第二个坐标表示"image2.jpeg"。

在这段代码中,我可以将标记更改为我的特定图像,谢谢
您需要执行IF
语句来确定标记应该加载哪个图像。
if(i == 0) iconImage = "image1.jpeg";
else if(i == 1) iconImage = "image2.jpeg";
然后将自定义图标和变量添加到标记中:
marker = new google.maps.Marker({
map:map,
draggable:true,
animation: google.maps.Animation.DROP,
position: a[i],
icon: iconImage
});
