[OpenLayers-Users] OPENLAYERS LayerChange

[Rahn Hanno (rahn)]

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");
                             }
                        }});
