我正在尝试传递一个参数以通过单击多边形来绑定它，我有以下内容：

var mapLayer = new L.TopoJSON(jsonMap, {style: style, onEachFeature: onEachFeature.bind(null,null,selectionManager), pane:'borders'}).addTo(this.map); 


 function onEachFeature(feature, layer, selectionManager) {
                    console.log(selectionManager)
                    layer.on({
                        mouseover: highlightFeature,
                        mouseout: resetHighlight,
                        click: dataFilter.bind(null,ID)
                    });
                }

 function dataFilter(selectionManager,e){
                    var layer = e.target;
                    var zoneName = layer.feature.properties.Index;
                    console.log(zoneName)
                    console.log(selectionManager);
                }

所以我的目标是读取 dataFilter 中的一个参数（在这种情况下是 selectionManager）
