## 场景 ##

Leaflet快速入门与加载OSM显示地图：

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

2、在线示例地址

[Leaflet.Pin Example][]

3、在线示例地址中右键查看网页源代码

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_20_color_FFFFFF_t_70_g_se_x_16 1][]

<!DOCTYPE html>
    <head>
        <meta charset="utf-8"/>
        <title>Leaflet.Pin Example</title>

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。

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_20_color_FFFFFF_t_70_g_se_x_16 2][]

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

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_20_color_FFFFFF_t_70_g_se_x_16 3][]

这里提供一下

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_14_color_FFFFFF_t_70_g_se_x_16][]

![bf9f4ab773b34722a22f4b88c251ec27.png][]

![6e8527618269462193377f0db9dfb6c3.png][]

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

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_19_color_FFFFFF_t_70_g_se_x_16][]

这里也提供一下

![bf11ab91c5bc446399feff4493d00db6.png][]

![c3b520f4172a45babe2fe82fe3c00946.png][]

将这两个图标放在leaflet.js所在目录下新建images目录下

![watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6Zy46YGT5rWB5rCT5rCU6LSo_size_20_color_FFFFFF_t_70_g_se_x_16 4][]

6、html完整示例代码
