Question

例如：想做一个简单的范围查询，以下面的代码为示例:

function query() {
        map.on('click',function (e){
    			var yuan=L.circle([e.latlng.lat,e.latlng.lng], {
                    color: 'green',
                    fillOpacity: 0.2, //透明度
                    radius: 1500000
                });
                Layer = yuan.addTo(map);
                
                var boundsParam = new SuperMap.GetFeaturesByBoundsParameters({
            datasetNames: ["World:Capitals"],
            bounds: Layer.getBounds()
        });
        L.supermap
            .featureService(url)
            .getFeaturesByBounds(boundsParam, function (serviceResult) {
                console.log(serviceResult.result.features);
                resultLayer = L.geoJSON(serviceResult.result.features, {
                    onEachFeature: function (feature, layer) {
                        layer.bindPopup(resources.text_capital+"：" + feature.properties.CAPITAL);
                    }
                }).addTo(map);
            });
                
                
                
        });        
       
        
    }

但是需要查询的url的数据既不是墨卡托又不是4326的坐标系，为他们使用的当地坐标系，怎么才可以查出来数据

您可以通过坐标系转换来实现查询的操作，具体的转换方法您可以参考这两篇博客https://blog.csdn.net/supermapsupport/article/details/101348811?ops_request_misc=%25257B%252522request%25255Fid%252522%25253A%252522160807916619724838552803%252522%25252C%252522scm%252522%25253A%25252220140713.130102334.pc%25255Fblog.%252522%25257D&request_id=160807916619724838552803&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~blog~first_rank_v1~rank_blog_v1-2-101348811.pc_v1_rank_blog_v1&utm_term=%E5%9D%90%E6%A0%87%E7%B3%BB
