I have a quite complex webapp with a lot of data on a map. Except the basemap, the data of each layers are coming from AJAX queries, witch's responses are formatted as GeoJSON object -- up to this works fine. (Each of this responses -- so each GeoJSON object -- can be more than 1 Mb.)

With checkboxes I'd like to show or hide the datasets.

I prepare each layer in this way: var layer_1 = L.geoJSON(null, { style: style_1, pane: "pane_1" }).addTo(myMap);.

I can add data: layer_1.addData(data_1.responseJSON);.

If I'd like to hide this dataset, is it possible somehow to remove only this dataset from layer_1 (as "opposite" of addData()), or the only way is to myMap.removeLayer(layer_1);, and then create the layer again?

On hand of these answer https://gis.stackexchange.com/a/218948/171957 it's possible to empty the dataset with jsonLayer.clearLayers().

  • This is not correct answer to the question. Method .clearLayers() clears all the features from the layer, but question is how to hide/remove only particular subset of layers.
