[mapserver-users] mapserver+javascript without template example?!!!

Mon Sep 10 04:46:02 PDT 2012

This is not related to mapserver. This is only html/form. There is no 
*substitution* of mapserver at all with this example.

Take a look at this documentation about html form: 
http://www.w3.org/TR/html401/interact/forms.html

Also, the reason why imxy input has some effect on the url sent is 
because it is missing its "end tag". See "value="[center]">" rather than
"value="[center]"/>"

Good Luck!

Alan
