If you want feature information from vector layers, use the 
SelectFeature control and configure it with an array of layers.

If you want to display WMS GetFeatureInfo responses, either use the 
WMSGetFeatureInfo control.

If you really want to work with a bare browser click event handler, like 
in the getfeatureinfo.html exmaple, you just need to add all the layers 
you want to query to the LAYERS param of the request, or, if the layers 
come from different WMS servers, issue one request for each server.

Regards,
Andreas.
