Delete Cluster Layers

LIZDean — Thu, 08 Aug 2024 06:06:49 GMT

I have some Javascript code that creates three cluster layers.

I need to be able to clear the three layers (workLayer, educationLayer, volunteerLayer) when I start a new process but can't figure out the right function.

This is what I have but it leaves the layers / graphics there.

function clearLayers() {

[workLayer, educationLayer, volunteerLayer].forEach(layer => {

if (layer.source) {

layer.source.remove()

}

});

}

Hi @LIZDean

FeatureLayer.applyEdits() - if you want to delete the features but leave the layers for later use
Map.removeMany() - if you want to remove the layer from the map but maybe readd it again
FeatureLayer.destroy() - if you want to destroy the reference to the layer and free up the memory. The layer and any associated resources no longer exist.
