MapGIS Client for JavaScript API

# new QueryFeaturesInLayersOptions(options)

参数:

示例

多图层要素查询使用示例

1.支持的服务类型
  const mapServer = new MapServer({
    url: "http://{ip}:{port}/igs/rest/services/{serverName}/MapServer",
  });
  const featureServer = new FeatureServer({
    url: "http://{ip}:{port}/igs/rest/services/{serverName}/FeatureServer",
  });
  const sceneServer = new SceneServer({
    url: "http://{ip}:{port}/igs/rest/services/{serverName}/SceneServer",
  });
  const featureServerV1 = new FeatureServer({
    url: "http://{ip}:{port}/igs/rest/mrfs/docs/{serverName}",
  });
  const featureServerGDBP = new FeatureServer({
    url: "http://{ip}:{port}/igs/rest/mrfs/layer",
  });
  const arcgisFeatureServer = new ArcGISFeatureServer({
    url: "http://{ip}:{port}/arcgis/rest/services/{serverName}/FeatureServer",
  });

  2.调用方法，以要素服务举例，其他服务跟要素服务调用方法一致
  2.1 几何过滤
  const queryFeaturesInLayersOptions = {
    layerDefs: [
      {
        layerId: "0",
        where: `1=1`,
        // 对于部分服务需要传入gdbp
        // gdbp: "gdbp://MapGISLocalPlus/湖北省/ds/行政区/sfcls/湖北省市级区划",
      },
      {
        layerId: "1-0",
        where: `1=1`,
        // 对于部分服务需要传入gdbp
        // gdbp: "gdbp://MapGISLocalPlus/湖北省/ds/行政区/sfcls/湖北省市级区划",
      },
    ],
    geometry: new Extent({
      xmin: 12579102.459639914,
      ymin: 3375646.034919311,
      xmax: 12690421.950433187,
      ymax: 3503549.8435043753,
      spatialReference: new SpatialReference("EPSG:3857"),
    }),
    geometryPrecision: 3,
    f: "json",
  }
  featureServer.queryFeaturesInLayers(queryFeaturesInLayersOptions)

  2.2 返回信息
  const queryFeaturesInLayersOptions = {
    layerDefs: [
      {
        layerId: "0",
        where: `1=1`,
        // 对于部分服务需要传入gdbp
        // gdbp: "gdbp://MapGISLocalPlus/湖北省/ds/行政区/sfcls/湖北省市级区划",
      },
      {
        layerId: "1-0",
        where: `1=1`,
        // 对于部分服务需要传入gdbp
        // gdbp: "gdbp://MapGISLocalPlus/湖北省/ds/行政区/sfcls/湖北省市级区划",
      },
    ]
  }
  featureServer.queryFeaturesInLayers(queryFeaturesInLayersOptions).then((res)=>{
    const data = res.data
    const layers = data.layers || []
    layers.forEach((layer) => { 
      const featureSet = layer.featureSet
    })
  })
