[mapserver-users] zoom extent

Mon Apr 14 02:20:52 EDT 2008

I think you should try strarting with mapserver basic, not javascript.
Mapserver CGI documentation (for functions) here: 
http://mapserver.gis.umn.edu/docs/reference/cgi/controls
Then, for the template (i.e. the html which embeds the map): 
http://mapserver.gis.umn.edu/docs/reference/templatereference/templatereference/view
I've never used javascript for functions such as zoom in, because 
mapserver itself has them already defined.
Good work.
