How to remove a polygon in google map?

Question

JavaScript

All good...!
Here is a link to the snippet https://jsfiddle.net/SlaXe/44s4885r/12/
If you just draw and then clear, then everything works, but if you first draw and then move the map, then the polygon is not deleted.
Same problem with markers.

Answer 1

Because your poly object is redefined every time, and the link to the old one is lost, so you can no longer remove them.
