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
https://github.com/Leaflet/Leaflet.draw
添加图层要素
删除图层要素
编辑图层要素

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
