Filter (no display) layers in GeoExt.LegendPanel with names LIKE some pattern

[المشرف العام]

This works to avoid Basemap layers such as Google Maps and overlays such as WMS to appear in the GeoExt Legend Panel:

var legendPanel = new GeoExt.LegendPanel({ border: false, filter: function(record){ if(!(record.getLayer().isBaseLayer) && (record.getLayer() instanceof OpenLayers.Layer.WMS)){ return true; } } }); The problem is that I need to filter (ie. no display) layers with names having "beam" in their names, I tried with no success this:

return record.getLayer().displayInLayerSwitcher == false && record.getLayer().name == '%beam%'; return record.getLayer().displayInLayerSwitcher == false && record.get("layer").name.indexOf("%beam%") == -1; return record.get("layer").name.indexOf("%beam%") == -1; Any hints are welcomed,
