场景

Leaflet快速入门与加载OSM显示地图：

https://blog.csdn.net/BADAO_LIUMANG_QIZHI/article/details/122290880

前面所引用的leaflet.js等都是线上url。下面借助于本地leaflet.js以及相应插件实现图层要素编辑效果。

此插件依赖于Leaflet.draw

Leaflet.draw

实现

1、插件地址

https://github.com/kklimczak/Leaflet.Pin

2、在线示例地址

https://kklimczak.github.io/Leaflet.Pin/

3、在线示例地址中右键查看网页源代码

4、依次点击源码中所用到的文件，并依次另存为到本地，在本地html中全部引入和修改路径。

5、这些文件中有些图标文件仍然需要

部分照片可以从这里获取

这里提供一下

 

 

leaflet.js中默认使用的marker的图标和其阴影的图标可以将在线示例网页中右键另存为里面去找

这里也提供一下

 

将这两个图标放在leaflet.js所在目录下新建images目录下
