Hello,

Great work.

I start and ,how can we retrieve the coordinates of the polygon in a "textarea" or, at least, display them all in an "alert"

Thanks

(je débute et ,comment peut on récupérer les coordonnées du polygone dans un "textarea" ou , au moins, toutes les afficher dans une "alert")

Hi,

you can call getData() function on the controller object. Next, you convert data to json strint with JSON.stringify

Example for https://github.com/tcoupin/leaflet-paintpolygon/blob/master/index.html#L41 :

alert(JSON.stringify(paintpolygonControl.getData()))

Just learning leaflet so please be patient with me. The control can create multiple polygons. Is it possible to get the coordinates of only the polygon that you just finished drawing after calling .stop(), or are all polygons related to the control treated as one set of data? The reason I ask is that I'd like the paint a polygon, then attach a tooltip, then paint another different polygon, then attach a different tooltip.
