Hi,
http://dev.openlayers.org/releases/OpenLayers-2.10/doc/apidocs/files/OpenLayers/Map-js.html#OpenLayers.Map.getLayersByName
var layers = Map.getLayersByName(name);
if(layers.length > 0) {
layers[0].setVisiblity(true);
layers[i].redraw();
}
if you are sure name is unique or
for(var i = 0; i <layers.length > 0 ;i++){
layers[i].setVisiblity(true);
layers[i].redraw();
}

the name - not the index i ?!?!??!

Subject: [OpenLayers-Users] Controll the Layervisibility by code
hi !
it is possible to define the visibility of a layer in the moment of
definition like
map.addLayer(new OpenLayers.Layer.OSM.Toolserver('osm-labels-en',
{isBaseLayer: false, visibility: true}));
but is it possible to control the visibility to a later time by code ??
i found following example:
for(var i=0;i<map.layers.length;i++)
{ Msg += map.layers[i].name + " :: " + map.layers[i].visibility +
"\r\n";
}
but how to define the status exactly to a layer-variable-name? [i] is
not a
name ?!?!?
regards Jan :-)
