Super,
That works. And how can I register a changelayer listener on the map? I try
this:
var options1 = {
maxExtent: new
OpenLayers.Bounds(662642.346412,152155.850000,726497.716088,206636.150000),
maxResolution:'auto',
numZoomLevels: '9',
fractionalZoom: true,
scales: [500000, 250000, 200000, 125000, 100000, 75000, 50000,
25000, 10000],
units: 'm',
projection: "EPSG:21781",
controls: []
};
var map = new OpenLayers.Map('map',options1,
eventListeners: {
"changelayer": function(e) {
if(e.property === "visibility") {
alert("visibility changed (" + e.layer.name + ")");
}
}
}
);
It doesn't work.
Thank you for your help.
Greetings

Try this:
var zielrichtung = new OpenLayers.Layer.WMS("Zielrichtung",urlArray,
{map:mapFile,layers:layerName,format:"image/png",EXCEPTIONS:"application/vnd.ogc.se_inimage"},
{singleTile: true, ratio:1, eventListeners: {
"visibilitychanged": function() {
alert("visibility changed");
}
}});
