定义locator标签

给点添加鼠标事件

//给点添加鼠标事件,用于显示其定位时间grahpic.addEventListener(MouseEvent.ROLL_OVER,onMapClick);                    grahpic.addEventListener(MouseEvent.ROLL_OUT,maouseOutHandler);

调用坐标转换地址的服务

private function onMapClick():void{　　var myp:MapPoint = new MapPoint(114.242593,30.631004,new SpatialReference(4326));　　var wm:MapPoint = WebMercatorUtil.geographicToWebMercator(myp) as MapPoint;　　locator.locationToAddress(wm,100);}

调用成功后的处理函数,与标签中的locationToAddressComplete属性配置的函数一致

private function onLocationToAddressComplete(event:LocatorEvent):void{ 　　var candidate:AddressCandidate = event.addressCandidate;　　if (candidate != null && candidate.address){　　　　WebMercatorUtil.geographicToWebMercator(candidate.location)　　　　var g:Graphic = new Graphic(candidate.location, sps, candidate.address);　　　　EsriGraphicsLayer.clear();　　　　EsriGraphicsLayer.add(g);　　　　var text:TextArea = new TextArea();　　　　text.htmlText = "地址:" + candidate.address.Address.toString();　　　　//+ "," + candidate.address.State.toString()　　　　EsriMap.infoWindow.content = text;　　　　EsriMap.infoWindow.show(g.geometry as MapPoint);              　　}            }

 失败后的回调函数

//回调失败时调用的函数protected function myService_faultHandler(event:FaultEvent):void{ 　　Alert.show(event.fault.message); }
