GUnload () for one google map

Question

I have Javascript / HTML code that displays a variable number of maps depending on what the user selects.

I worked on how to dynamically create multiple maps on a page that are well-documented.

However, I'm not sure if this is ... how can I safely destroy a map after creating it? Usually I just leave this to GUnload () for sorting.

Thanks for any help!

Unfortunately, the Google Maps API has not yet provided a documented method for the separate map's GUnload() .

There is open Issue No. 772 for this feature in the Google Maps API Issue Tracker. On May 24, 2009, it was marked as “Confirmed,” but it remains open to this day.

In the first comment on this issue, a member of the Google Maps team confirmed that a possible “partial” workaround at the moment is to call

 map_to_delete.clearOverlays(); GEvent.clearInstanceListeners(map_to_delete);
