[OpenLayers-Users] add layer name in dropdown box from geoserver

[Phil Scadden]

Issue WMS GetCapabilities eg
                                        Ext.Ajax.request({
                                         url: "adminproxy.jsp",
                                         success: addWmsData,
                                         params:{url: layerUrl + 
"service=WMS&request=GetCapabilities&version=1.1.1"}
                                        });
where the callback looks something like this:

function addWmsData(response){
                    wmsGetCapabilitiesDocument = response.responseXML;
                    wmsGetCapabilitiesParsed = new 
OpenLayers.Format.WMSCapabilities.v1_1_1().read(wmsGetCapabilitiesDocument);
                    var layerData = [];
                    var tmp=-1;
                    for (i = 0; i < 
wmsGetCapabilitiesParsed.capability.layers.length; i++) {
                                        var layer = 
wmsGetCapabilitiesParsed.capability.layers[i];
                                        layerData[i] = [layer.name, 
layer.title];
                    }
// now use the layerData array as a store for a combo box.
                    availableLayerStore.loadData(layerData);
}

The above is for using an Ext Store to an ext combo box, but you should 
be able to use something similar for whatever your framework is.
