[OpenLayers-Users] WMS GetFeatureInfo results in new window

[Arnd Wippermann]

MapServer offers the possibility to show a specific html side, when there
are no results. 

Add EMPTY to the WEB part of the map
EMPTY 'Templates/empty.html' 

Or you can change the tolerance radius for selecting a point.

Betreff: [OpenLayers-Users] WMS GetFeatureInfo results in new window

I want to put the results of a WMS GetFeatureInfo into a new window.
Instead of calling loadURL, I'm using open, like this

  var url =  wms.getFullRequestString({
    REQUEST: "GetFeatureInfo",
    EXCEPTIONS: "application/vnd.ogc.se_xml",
    BBOX: wms.map.getExtent().toBBOX(),
    X: e.xy.x,
    Y: e.xy.y,
    INFO_FORMAT: 'text/html',
    QUERY_LAYERS: wms.params.LAYERS,
    WIDTH: wms.map.size.w,
    HEIGHT: wms.map.size.h});
  // OpenLayers.loadURL(url, '', this, setHTML);
  open(url);

This works well when the user has hit a feature.  For polygon data that is
easy for users, because polygons are normally large.  But for point
features, it is more likely that the user will "miss"--click on a place that
does not select a feature.  My simple code still opens a new window, which
is now empty, leaving a confused and frustrated user.

What might I do differently so that a feature miss would not result in an
empty new window?
