API methods

add(geojson: Object) => Array

添加一个地图要素，并返回一个包含地图要素的id的数组，用于二次编辑

var feature = {
  id:'unique-id',
  type:'Feature',
  properties:{},
  geometry:{type:'Point', coordinates:[0, 0]}
};
var featureIds = draw.add(feature);
console.log(featureIds)
//=> ['unique-id']

get(featureId: string): ?Feature

返回指定id的GeoJSON，如果id不存在，则返回undefined

getFeatureIdsAt(point: { x: number, y: number }): Array

返回当前在指定点处的要素的要素ID数组 point参数需要来自像素空间的x，y坐标，而不是经纬度

var featureIds = Draw.getFeatureIdsAt({x:20, y:20});
console.log(featureIds)
//=> ['top-feature-at-20-20', 'another-feature-at-20-20']

getSelectedIds(): Array

返回当前所选要素的要素ID数组

getAll(): FeatureCollection

返回地图上所有要素的FeatureCollection

delete(ids: string | Array): draw

删除具有指定ID的要素，返回图形的实例

var feature = { type:'Point', coordinates:[0, 0] };
var ids = draw.add(feature);
draw
  .delete(ids)
  .getAll();
//{ type:'FeatureCollection', features:[] }

deleteAll(): draw

删除地图上所有要素

setFeatureProperty(featureId: string, property: string, value: any): draw

根据指定的id，设置要素上的属性值。 返回图形的实例

Draw Event

draw.create

图形被创建时的事件

draw.delete

图形被删除时的事件

draw.update

图形被更新时的事件，如拖拽或平移操作

draw.modechange

改变绘制图形类型时的事件

Function
