public function ChartQueryService(url:String = null)
使用服务地址 URL 实例化 ChartQueryService 对象。
参数
|
url:String (default = null) — 地图查询服务访问地址。如："http://192.168.168.35:8090/iserver/services/map-ChartW/rest/maps/海图"。 |
下面示例显示了如何进行海图属性查询：
private var chartMarkCode:int;//物标代码
protected function queryBtn_clickHandler(event:MouseEvent):void
{
var filterParam:ChartQueryFilterParameter = new ChartQueryFilterParameter();
filterParam.isQueryLine = true;
filterParam.isQueryPoint = true;
filterParam.isQueryRegion = true;
filterParam.attributeFilter = "SMID < 10";
filterParam.chartFeatureInfoSpecCode = chartMarkCode;//查询的物标代号,可通过海图物标信息服务类（ChartFeatureInfoSpecsService）获得
var queryPram:ChartQueryParameters = new ChartQueryParameters();
queryPram.queryMode = ChartQueryMode.ChartAttributeQuery;
queryPram.chartLayerNames = ["GB4X0000_52000"];
queryPram.returnContent = true;
queryPram.chartQueryFilterParameters = [filterParam];
var chartQueryService:ChartQueryService = new ChartQueryService(mapUrl);
chartQueryService.processAsync(queryPram,new AsyncResponder(successHandler,
function (object:Object, mark:Object = null):void
{ Alert.show("与服务端交互失败", "抱歉", 4, this);
},null));
}
private function successHandler(result:QueryResult,object:Object = null):void
{
//TODO
}
<s:Button top="3" id="queryBtn" label="查询" click="queryBtn_clickHandler(event)"/>
