L.Path.Drag

Drag handler for Leaflet vector features. It adds dragging API and events of L.Marker to L.Polygon and L.Polyline.

If you are looking for this functionality combined with Leaflet.draw, take a look at Leaflet.draw.drag and Leaflet.Editable.Drag.

Demo

Usage

<script src="path/to/leaflet/"></script>
<script src="path/to/L.Path.Drag.js"></script>
...
var polygon = new L.Polygon([...], { draggable: true }).addTo(map);
// you can use the drag events just like with markers
polygon
    .on('dragstart', onDragStart)
    .on('drag',      onDrag)
    .on('dragend',   onDragEnd);

with browserify

npm install leaflet-path-drag
...

require('leaflet');
var handler = require('leaflet-path-drag');

Requires Leaflet@1.1.x

For Leaflet@0.7.x support use code from leaflet-0.7 branch

Enable/disable dragging

var polygon = new L.Polygon([...], { draggable: true }).addTo(map);
polygon.dragging.enable();
polygon.dragging.disable();

Info

It uses matrix transforms on SVG/VML paths, so part of it(src/L.Path.Transform) could be used for different transformations - skew/scale/etc - but you have to provide coordinates projection and handling yourself.

VML matrix transform tested in IE8, it has rendering glitches, but what can you expect.
