Flex调用WebServer数据与XML基础地图数据进行匹配渲染

1.查找WebServer接口数据

/**
??? * 通过调用WebService来获取数据
??? * @param date 调用该日期的数据
??? */
???private function getDataByWebservice():void
???{
????
????var serviceLabel:String = configXML.webService.estuariesLaterWebService.@serviceLabel;
????var functionName:String = configXML.webService.estuariesLaterWebService.@functionName;
????var webServiceUrl:String = configData.webService[serviceLabel];
????
????var obj:Object=new Object();
????obj.year=ddlYear.selectedItem.toString().substr(0,4);
????obj.month=ddlMonth.selectedItem.toString().substring(0,ddlMonth.selectedItem.toString().indexOf("月"));
????var object:Object=new Object();
????object.filterParams=obj;
????var where:String=JSON.encode(object);
????
????resultLabel.text="0";
????//resultLabel.visible=false;
????MapUni.callWebService(webServiceUrl,functionName,[where],onGetData);
????
???}
???
???/**
??? * 监听成功调取数据
??? */
???private function onGetData(event:ResultEvent):void
???{
????monitorValueLayer.clear();
????layerxuanran.clear();
????
????var dataStr:String = event.result.toString();
????if(dataStr)
????{
?????var dataAry:Array = JSON.decode(dataStr);
?????dataGrid.dataProvider =arrangeData(dataAry);
?????
//?????stationDgc.dataField = configXML.dataField.estuariesDataField.@stationName;
?????sectionDgc.dataField = configXML.dataField.estuariesDataField.@sectionName;
????}
????XuanranRiver();//渲染河流
???}

2.查找XML基础地图数据

?

/**
??? * 获取所有河流图层
??? **/
???private var heliuArr:Array=new Array();
???
???private function getAllRegionName():void
???{
????var layerName:String=configXML.layers.RiverLayer.@layerName;
????var layerURL:String=MapUni.layerUrl(map,layerName);????
????MapUni.search(layerURL,null,"1=1",onSearchResult);
????//onSearchResult是查询到的地市结果
????function onSearchResult(featureSet:FeatureSet):void
????{
?????//将查询到的结果放在数组里??? 里面是十一个地市
?????heliuArr=featureSet.features as Array;
????}
???}

?

3.WebServer接口数据与XML基础地图数据进行匹配渲染

/** ??? * 渲染匹配河流 ??? */ ???private var simplsy:SimpleLineSymbol; ???private function XuanranRiver():void ???{ ????layerxuanran.clear();//清空图层 ???? ????for each(var heliuGra:Graphic in heliuArr) ????{ ?????var attribute:Object=heliuGra.attributes; ?????var heliuName:String=attribute.NAME; //?????var oo:Object=fader.play(); ?????for(var i:int=0;i<dataArr.length;i++) ?????{ ??????var graphicnew:Graphic=heliuGra as Graphic; ??????var obj:Object=graphicnew.attributes; ??????if(heliuName==dataArr[i].RiverName) ??????{ ???????var graphic:Graphic=new Graphic(graphicnew.geometry,obj); ???????layerxuanran.add(graphic); ???????simplsy=new SimpleLineSymbol("solid",0x0000FF,0.9,3); ??????? ???????graphic.symbol = simplsy; ???????break; ??????} ?????} ????}? ???? ???? ???}
