What I'm trying to do:
I'm rending a map for an entire county. I have a simply html select
option of extents that I wish to use to set focus on the map. I need to
restrict the user from being able to zoom 'out' (pull back and see the
entire county) or slide 'away' (drag the map to another area) after an
option has been selected.
I currently initialize the map to the county view when the page loads
(see http://pastebin.com/jSmnHtwS for HTML). I have written a function
which will zoom to a new extent based on the selection of the option
fine, but I'm stuck with how I can restrict the user from zooming 'out'
or slipping 'away' from the focused extent.
I'm looking for any suggestions on what might be the best approach to
achieve my objective.
