Supermap iserver client 空间查询关联属性过滤示例

点查询并根据属性条件过滤示例代码

//关联外表

var joinItem=new SuperMap.REST.JoinItem({

foreignTableName: "V_REGION_LAND",

joinFilter: "BBS_PARCEL.CADASTRALNO = V_REGION_LAND.CADASTRALNO ",

joinType: "INNERJOIN"

});

var queryParam, queryByGeometryParameters, queryService;

queryParam = new SuperMap.REST.FilterParameter(

{

name: "[email protected]_sysdb",

joinItems:joinItem,

attributeFilter:" V_REGION_LAND.FJBM="+_disCode//外表条件过滤

});

queryByGeometryParameters = new SuperMap.REST.QueryByGeometryParameters({

queryParams: [queryParam],

geometry: drawGeometryArgs.feature.geometry,

spatialQueryMode: SuperMap.REST.SpatialQueryMode.INTERSECT

});
