Question

获取当前鼠标的坐标，然后转换坐标，然后构造点对象，最后GetFeaturesByGeometryParameters查询返回“GetFeaturesByGeometryParameters”， 可是传入的geometry不是空的啊。在iserver里面又可以查出来。

				var latlng = event.latlng;	
				var point_old = L.latLng(event.latlng.lat,event.latlng.lng);
                var point_new = L.CRS.EPSG3857.project(point_old);
                var point = L.point(point_new.x, point_new.y);
                // var geometry = new SuperMap.Geometry.Point(point_new.x, point_new.y);
    //             var point = {"points":[{"y": 100, "x": 30}],"type":"POINT"};
				// var geometry = eval(point);
		        var geometryParam = new SuperMap.GetFeaturesByGeometryParameters({
		            datasetNames: ["all:test"],
		            geometry: point,
		            spatialQueryMode: "INTERSECT"
		        });
		        L.supermap
		            .featureService(dataUrl)
		            .getFeaturesByGeometry(geometryParam, function (serviceResult) {
		            	console.log('serviceResult:', serviceResult);
		                // resultLayer = L.geoJSON(serviceResult.result.features, {
		                //     onEachFeature: function (feature, layer) {
		                //         layer.bindPopup(resources.text_country + "：" + feature.properties.COUNTRY);
		                //     }
		                // }).addTo(map);
		            });

求大神指点---在线等

您好，创建点对象需要用的接口是 var point=L.circle([-10, 30], {radius: 200}).addTo(map);

不是var point = L.point();

您用我这个方法在试一下。
