I also agree with K9soul. Dog's just don't do things that way. We put human emotions such as anger and resentment on them that they just don't possess. You need to think like a dog with siutations like this. YOu can either move the toys and keep your bedroom door shut, or like someone else mentioned, for now keep a piece of noisy plastic or a shower curtain on the bed so that if she jumps up she won't like the sound, and if she does jump up and pee, then your bed is protected. You would be better off trying to keep the door closed though. I agree also that if you are seeing her do this there is a good possibility she is scared when she sees you and she is on the bed and pees out of fear at the time.

Being destructive doesn't mean they are trying to "get you back". They aren't like people. Most likely a dog who has done something destructive either likes playing with or chewing on whatever they destroyed, or was very bored. My guess is the dog is confused and peed on the bed out of submissive/fear urination. Dog's don't have "revenge" thoughts in that way.
