arcgis api for JavaScript 求 RasterDataSource相关例子

     function (DynamicLayerInfo, QueryDataSource, LayerDataSource, RasterDataSource,ArcGISDynamicMapServiceLayer,Map) {

                var url="http://localhost:6080/arcgis/r ... 3B%3B

                var dynamicData=new ArcGISDynamicMapServiceLayer(url);

                var map=Map("map");

                map.addLayer(dynamicData)



                document.getElementById('addLayer').onclick = function () {



                    var dynamicLayerInfos = ;

                    var dynamicLayerInfo = new DynamicLayerInfo();

                    dynamicLayerInfo.id = 1;

                    var dataSource = new RasterDataSource();

                    dataSource.workspaceId = "MyRasterWorkspaceID";

                    dataSource.dataSourceName = "090161.tif";



                    var layerSource = new LayerDataSource();

                    layerSource.dataSource = dataSource;

                    dynamicLayerInfo.source = layerSource;

                    dynamicLayerInfos.push(dynamicLayerInfo);



                    dynamicData.setDynamicLayerInfos(dynamicLayerInfos);



                };
