Dude: Save & Redraw

[marcoas]

(Tanslated By Google)
In my project, I need only would use "polylines".
How I can get all the points of the polyline to save (in a database)?
And How I can redraw a polyline, knowing the points that compose?

(Spanish)
En mi proyecto, solamente necesito usaría "polylines".
¿Como puedo obtener todos los puntos del polyline para poder guardarlos (en una base de datos)?
Y ¿Como puedo volver a dibujar un polyline, sabiendo los puntos que lo componen?

@marcoas If you have leaflet polylines on your map, you can convert them to geojson with the built-in Leaflet method.

Here is the documentation:

http://leafletjs.com/reference.html#polyline

line = lineLayer.toGeoJSON();
var coordinates = line.geometry.coordinates;

// do something with coordinates

If you have a list of coordinates, you can do the following:

http://leafletjs.com/examples/geojson.html

var coordinates = [] // get these from your database

// create a geojson object
var line = {
  type: 'Feature',
  geometry: {
    type: 'LineString',
    coordinates: coordinates
  },
  properties: {}
};

L.geoJson(line).addTo(map);
