Greetings,
Yes, it is possible to do this. After you create the ArcIMS layer, set up
the mouse click event to call something like:
function mapclick( e ){
layer.getFeatureInfo( openlayers_map.getLonLatFromPixel( e.xy ),
layer.options.layers[0],
{
callback: clickresult,
scope: window
}
);
}
};
function clickresult(features){
if ( features !== null ) {
vector.addFeatures( features.feature );
}
};
Where "layer" is your arcims layer, "layer.options.layers[0]" is a layer
definition ArcXML needs a layer to query. In the callback, "features" is an
object that corresponds to the ArcXML "FEATURES" element, and "vector" is
your vector layer where you want your features. There is no need to
manually parse the response, it is handled before the getFeatureInfo
callback is invoked.
Just to let you know, there is a 1 map unit buffer by default. This may not
be desireable, especially if you are working in EPSG:4326 (a 1 degree buffer
may be massively huge).
