[ka-Map-users] Re: mapserver query system in kamap

Sat Sep 29 15:30:30 EDT 2007

I hope this can help you to understand:

if I use the query tool, the resultant window shows the message I posted 
in the previous email, but if copy the generated query (for example 
http://www.openmaps.it/cgi-bin/mapserv?map=/usr/local/apache2/webdomains/gisst/home/mapfiles/majella.map&mode=query&mapxy=419523.1067908557)
and paste it in a new browser window I obtain the following error:

loadForm(): Web application error. Not enough arguments for mapxy

I suppose (but not sure) this means that the code in the wiki

function myQuery( eventID, queryType, coords ) {

window.open("/cgi-bin/mapserv?map=/absolute/path/to/my/mapfile.map&mode=query&mapxy=" 
+ coords[0] + "+" + coords[1]);
}

is not enough to generete a full working query...
I hope you can help me!
