网络营业路测数据展示技术之扇区查询及选择模式切换

本示例中使用ArcGIS for Flex API进行演示，扇区数据查询有两种方法，一种是使用控件初始化，另一种为代码动态生成，分别如下：

一、

<esri:FeatureLayer id="sanqu" url="http://*.*.*.*:8000/arcgis/rest/services/lianTong/MapServer/0"

                           outFields="*"

                           symbol="{defaultsym}"

                           mode="onDemand"

                           >

            <esri:infoWindowRenderer>

                <fx:Component>

                    <mx:VBoxbackgroundColor="0xffffff"

                            color="0x444444"

                            label="Parcel {data.PARCELID}">

                       <mx:Labeltext="OBJECTID : {data.OBJECTID}"/>

                       <mx:Labeltext="方位角: {data.AZIMUTH}"/>

                       <mx:Labeltext="角度: {data.CENTERANGLE}"/>

                       <mx:Labeltext="半径: {data.RADIUS}"/>

                   </mx:VBox>

                </fx:Component>

            </esri:infoWindowRenderer>

        </esri:FeatureLayer>

二、

<esri:FeatureLayer id="sanqu" url="http://*:8000/arcgis/rest/services/lianTong/MapServer/0"

                           outFields="*"

                           click="sanqu_clickHandler(event)"

                           symbol="{defaultsym}"

                           mode="onDemand"

                           >          

        </esri:FeatureLayer>

            //扇区图层点击事件

            protectedfunctionsanqu_clickHandler(event:MouseEvent):void

            {

                // TODO Auto-generated method stub

                if (event.target is Graphic ||event.target.parent is Graphic)

                {

                   var gr:Graphic =Graphic(event.target);  

                   gr.symbol=(gr.symbol==clickSymbol?defaultsym:clickSymbol);

                   myTextArea.htmlText= "<b>OBJECTID: </b>" + gr.attributes.OBJECTID.toString() + "\n"

                       +"<b>方位角: </b>" + gr.attributes.AZIMUTH.toString() + "\n"

                       +"<b>中心夹角: </b>" + gr.attributes.CENTERANGLE  + "\n"

                       +"<b>半径:</b>" +gr.attributes.RADIUS ;

                   MyMap.infoWindow.label= gr.attributes.OBJECTID;                 

                   MyMap.infoWindow.show(MyMap.toMapFromStage(event.stageX,event.stageY));               

                }

            }

效果如下图所示：
