Use something like jQuery (my Js weapon of choice) to construct an ajax query. A JSONP query requires just one additional letter "P". 2. Use a proxy. Remember, a few days ago I was asking about how to specify different classes in the browser address bar (in the URI) and use that to specify which classes are rendered by MapServer? I solved that by using a proxy... just a couple of lines of Perl, and that was solved. A bonus hint -- if your data are in Pg, don't even bother with getFeatureInfo. Just query the db directly and return the data as JSON (or, JSONP, in this case). -- Puneet Kishor_______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
