[mapguide-users] Re: Viewer API GetLayer() and base layers

[Tom Chadwin]

OK, I've got it working via AJAX now (without jQuery and JSON, actually, as
it's such a simple call), but I am left with having to make the AJAX request
repeatedly (every 2 seconds or so). Is there some event hook I can use so
that I only have to call this function when the map changes (zoom or change
layer visibility via the legend)?

Thanks for all the help

Tom
