Re: why can't it be global variable, var map = new google.maps.Map ?
Chad Killingsworth
interface makes me go cross-eyed. I also can't use any handy debugging
tools . . .
If I had to guess to your problem though, with the map as a global
variable the constructor is trying to create the map before the DOM
node is ready so it can't be accessed yet.

use "var window.map" or just remove "var" from here and define var map
somethere in the top of script
and then toy create NEW MAP( again - NEW MAP ) in click event.
remove that lines where.
Brak
what you want to do is create a new map every time someone clicks your
polygon. That would not only be unintuitive but you'd have load time
concerns and you wouldn't be able to carry much over from map to map.
What I'd do if I understand you correctly is create an array with all
of your polygons in it, then create one map. Apply/draw the first
polygon during your Initialize function and set a global index
variable to "0". Then in your polygon click event function, un-draw
(set map: to null) your current polygon, increment your index
variable, then draw your next polygon. This will be much faster for
the user and the code. -- That is of course, if I understood what you
wanted to do initially properly.
