You can't, unless you somehow remember which markers you put on the map in order to remove them later. The usual approach is to store added markers in an array. When you want to remove them all, iterate through the array and remove each, then clear the array. There are more sophisticated approaches, like checking 'new' markers against 'old' ones in your array so as to avoid removing/adding the same marker. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
