I am a newbie to OpenLayers and I have followed the KML example. I have spent
hours searching through previous posts for an answer.
Firefox and Opera: The pop up works on Firefox but only displays the name.
The description displays "undefined". <br />
IE :both the "name" and "description text appears.
You can see it here

my kml test
Here's my code:
var lon = 11.8;
var lat = 64.5;
var zoom = 5;
var map, layer, gmap, kmlLayer, selectControl;
function init(){
map = new OpenLayers.Map('map');
layer = new OpenLayers.Layer.WMS( "OpenLayers WMS",
"http://labs.metacarta.com/wms/vmap0", {layers:
'basic'}, {isBaseLayer: true});
map.addLayer(layer);
map.addControl(new OpenLayers.Control.LayerSwitcher());
kmlLayer = new OpenLayers.Layer.GML("KML",
"http://www.sjokart.no/admin/filestore/Sjkartverket/kml/vannstandstasjoner2.kml",
{
format: OpenLayers.Format.KML,
formatOptions: {
extractStyles: true,
extractAttributes: true,
maxDepth: 2
}
});
map.addLayer(kmlLayer);
map.setCenter(new OpenLayers.LonLat(lon, lat), zoom);
selectControl = new OpenLayers.Control.SelectFeature(kmlLayer);
kmlLayer.events.on({
"featureselected": onFeatureSelect,
"featureunselected": onFeatureUnselect
});
map.addControl(selectControl);
selectControl.activate();
function onPopupClose(evt) {
selectControl.unselectAll();
}
function onFeatureSelect(event) {
var feature = event.feature;
var detail = feature.attributes['description'];
var content = "<div style='font-size:.8em; width:120px;'><strong>"+
feature.attributes.name + "</strong><hr />" + detail + "</div>";
popup = new OpenLayers.Popup.FramedCloud("chicken",
feature.geometry.getBounds().getCenterLonLat(),
new OpenLayers.Size(100,100),
content,
null, true, onPopupClose);
popup.border = '1px solid black';
popup.opacity = .7;
popup.panMapIfOutOfView = true;
feature.popup = popup;
map.addPopup(popup);
}
function onFeatureUnselect(event) {
var feature = event.feature;
if(feature.popup) {
map.removePopup(feature.popup);
feature.popup.destroy();
delete feature.popup;
}
}
}
This is my kml code:
