如何从小叶多边形

Question

我使用Leaflet绘制绘制多边形。我成功地做到了这一点，但是当我点击编辑时，我可以编辑多边形，但它并没有将坐标转换为HTML，坐标＆＃34; field..how我可以这样做吗？是搞砸了吗？谢谢！我将坐标保存为MYSQL数据库为VARCHAR。谢谢！

我可以从数据库中获取旧坐标，但是当我编辑它时，它并没有改变，geolocatii＆＃34;领域

也许BBox工具将对您有所帮助：

http://bboxfinder.com/#0.000000,0.000000,0.000000,0.000000

https://github.com/aaronr/bboxfinder.com

该工具基于传单绘制插件，并配有坐标网格。绘制框后，即可在URl路径中获得坐标。
