Pretty much the same thing I'm doing on my map. This is the
simplified version: I have an array that has all the bits and pieces I
need, including the polyline's vertex points. I have a routine that
calls either map.addOverlay(polyline) or map.removeOverlay(polyline)
based on a status variable. And my checkbox (not radio button) calls
the toggle function like so:
<input type="checkbox" id="polyline_1" onclick="(this.checked) ? toggle
('polyline_1', 1) : toggle('polyline_1', 0);"> Toggle polyline
Things to keep in mind:
your function needs to set the checkbox status each time you call it
(document.getElementById(rOverlay).checked = [FALSE or TRUE]; )
If you're adding an event listener to your polyline, it needs to
happen outside of the toggle function for proper closure.
