|

* Leaflet.draw assumes that you have already included the Leaflet library.

/**
|
||
|
|
* @class L.Draw
|
||
|
|
* @aka Draw
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* To add the draw toolbar set the option drawControl: true in the map options.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* ```js
|
||
|
|
* var map = L.map('map', {drawControl: true}).setView([51.505, -0.09], 13);
|
||
|
|
*
|
||
|
|
* L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
|
||
|
|
* attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
|
||
|
|
* }).addTo(map);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ### Adding the edit toolbar
|
||
|
|
* To use the edit toolbar you must initialise the Leaflet.draw control and manually add it to the map.
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var map = L.map('map').setView([51.505, -0.09], 13);
|
||
|
|
*
|
||
|
|
* L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
|
||
|
|
* attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
|
||
|
|
* }).addTo(map);
|
||
|
|
*
|
||
|
|
* // FeatureGroup is to store editable layers
|
||
|
|
* var drawnItems = new L.FeatureGroup();
|
||
|
|
* map.addLayer(drawnItems);
|
||
|
|
*
|
||
|
|
* var drawControl = new L.Control.Draw({
|
||
|
|
* edit: {
|
||
|
|
* featureGroup: drawnItems
|
||
|
|
* }
|
||
|
|
* });
|
||
|
|
* map.addControl(drawControl);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The key here is the featureGroup option. This tells the plugin which FeatureGroup contains the layers that
|
||
|
|
* should be editable. The featureGroup can contain 0 or more features with geometry types Point, LineString, and Polygon.
|
||
|
|
* Leaflet.draw does not work with multigeometry features such as MultiPoint, MultiLineString, MultiPolygon,
|
||
|
|
* or GeometryCollection. If you need to add multigeometry features to the draw plugin, convert them to a
|
||
|
|
* FeatureCollection of non-multigeometries (Points, LineStrings, or Polygons).

||

|
|
* The core toolbar class of the API — it is used to create the toolbar ui
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* ```js
|
||
|
|
* var modifiedDraw = L.drawLocal.extend({

|
* draw: {
|

|
|
* toolbar: {

|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The default state for the control is the draw toolbar just below the zoom control.
|
||
|
|
* This will allow map users to draw vectors and markers.
|
||
|
|
* **Please note the edit toolbar is not enabled by default.**

* ### Events
|
||
|
|
* Once you have successfully added the Leaflet.draw plugin to your map you will want to respond to the different
|
||
|
|
* actions users can initiate. The following events will be triggered on the map:
|
||
|
|
*
|
||
|
|
* @class L.Draw.Event
|
||
|
|
* @aka Draw.Event
|
||
|
|
*
|
||
|
|
* Use `L.Draw.Event.EVENTNAME` constants to ensure events are correct.
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* ```js
|
||
|
|
* map.on(L.Draw.Event.CREATED; function (e) {
|
||
|
|
* var type = e.layerType;
|
||
|
|
* layer = e.layer;
|
||
|
|
*
|
||
|
|
* if (type === 'marker') {
|
||
|
|
* // Do marker specific actions
|
||

|
* }
|
||
|
|
*
|
||
|
|
* // Do whatever else you need to. (save to db; add to map etc)

/**
|

|
|
* @class L.Draw.Toolbar
|
||
|
|
* @aka Toolbar
|
||
|
|
*
|
||
|
|
* The toolbar class of the API — it is used to create the ui
|
||
|
|
* This will be depreciated
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var toolbar = L.Toolbar();
|
||
|
|
* toolbar.addToolbar(map);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ### Disabling a toolbar
|
||
|
|
*
|
||
|
|
* If you do not want a particular toolbar in your app you can turn it off by setting the toolbar to false.
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var drawControl = new L.Control.Draw({
|
||
|
|
* draw: false,
|
||
|
|
* edit: {
|
||
|
|
* featureGroup: editableLayers
|
||
|
|
* }
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ### Disabling a toolbar item
|
||
|
|
*
|
||
|
|
* If you want to turn off a particular toolbar item, set it to false. The following disables drawing polygons and
|
||
|
|
* markers. It also turns off the ability to edit layers.
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var drawControl = new L.Control.Draw({
|
||
|
|
* draw: {
|
||
|
|
* polygon: false,
|
||
|
|
* marker: false
|
||
|
|
* },
|
||
|
|
* edit: {
|
||
|
|
* featureGroup: editableLayers,
|
||
|
|
* edit: false
|
||
|
|
* }
|
||
|
|
* });
|
||
|
|
* ```
