In my design there's a checkbox which removes all vector layers with the following code.
// When I check that checkbox:
var layers = map.getLayersByClass('OpenLayers.Layer.Vector');
for(var j=0; j < layer_vectors.length; j++){
map.removeLayer(layer_vectors[j]);
}
Which works fine. I need to remove all with this way because there're many vector layers which contain polygons.
What if I have two different group of vector layers? How can I remove only one of them by that checkbox?
Can we set something like a "data-layertype" attribute as in normal html elements? How can I distinguish two different layers after I get them with getLayersByClass?
Thanks
OK I solved this problem. I set whole group with the same name each time when I create the vector layer and when I remove the layers I distinguish them with their ".name" attribute.
for(var j=0; j < layer_vectors.length; j++){
if(layer_vectors[j].name == "group_name"){
map.removeLayer(layer_vectors[j]);
}
}
