如何在传单中显示不同缩放级别的不同图层

Question

我现在可以看到如下所示的折线：

geojson = L.vectorGrid.slicer(lines, {

    vectorTileLayerStyles: {
        sliced: style},

        maxZoom: 24, // max zoom to preserve detail on
        interactive: true,
        getFeatureId: function(f) {
            return f.properties.id;
        }

}).on('mouseover', mouseover_function).addTo(map);
searchCtrl.indexFeatures(lines.features, ['id']);
info.addTo(map);

这些行是所有多边形线的geoJSON文件。现在我将我的线分为3部分geoJSON并且

lines_1
lines_2
lines_3

所以我创建了三层以上三层

geojson1 = L.vectorGrid.slicer(lines1, {

        vectorTileLayerStyles: {
            sliced: style},

            maxZoom: 24, // max zoom to preserve detail on
            interactive: true,
            getFeatureId: function(f) {
                return f.properties.id;
            }

    }).on('mouseover', mouseover_function).addTo(map);


geojson2 = L.vectorGrid.slicer(lines2, {

        vectorTileLayerStyles: {
            sliced: style},

            maxZoom: 24, // max zoom to preserve detail on
            interactive: true,
            getFeatureId: function(f) {
                return f.properties.id;
            }

    })


geojson3 = L.vectorGrid.slicer(lines3, {

        vectorTileLayerStyles: {
            sliced: style},

            maxZoom: 24, // max zoom to preserve detail on
            interactive: true,
            getFeatureId: function(f) {
                return f.properties.id;
            }

    })

所以这是三层，我想在缩放等级20和缩放等级22的geojson3的所有放大级别和geojson3上显示geojson1。

如何在不同的缩放级别上显示这些图层。

感谢任何帮助。
