将默认标记更改为谷歌地图API上的特定图像

Changing the default marker to a specific image on google maps API

本文关键字：API 图像 谷歌地图 默认      更新时间：2023-09-26

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
});
