问题
Google Maps API v3 currently supports two types of animation for markers: DROP and BOUNCE
Is there a way I can speed up the BOUNCE or slow down the DROP animation?
回答1:
Google Maps API doesn't support animation properties or customization, just the ability to select "drop" or "bounce" as you said.
It should be possible to apply custom animations to marker elements through jQuery or other framework. Alternatively you could supply an animated GIF as a marker.
