Ok - I've sorted that problem. I was doing getElementByID, but unless
that ID was open, there was no ID to get - so the javascript was
throwing an error. For the moment I've stuck the getelementbyid into a
try/catch statement, so that the getelementbyid updates the window if
it is open, otherwise the event listner is changed as before.
Query though:
I have been changing the event listner by calling:
google.maps.event.addListener(markerArray[id], 'click', function()
{ ....}
This would seem to mean that after a few itterations, every marker
will have many click listners. Is this the case, and if so, any
thoughts as to how I can replace the listner rather than add another?
Cheers
