<body>   
    <div id="myMap"  style="width:100%;height:900px"></div>

 把点传到数据服务中查询,然后返回结果。我这边在配置GetFeaturesByGeometryParameters参数的时候拿不到点,不知道为什么geometry是空的。用的是iClient for Leaflet API

您好,代码如下:

var point = L.circleMarker([30, 104]);

var geometryParam = new SuperMap.GetFeaturesByGeometryParameters({
datasetNames: ["World:Countries"],
geometry: point,
spatialQueryMode: "INTERSECT"
});
