It sounds like you got her right back in to the tank as soon as she jumped out. She's probably a bit stressed from the experiance, so I'd leave her in low light for the day.
If she has trouble swimming or reaching the surface (remember, fish sleep and after the stress, she may want to do a bit of that), you can put your betta in a floating container in the tank, with just enough water to cover her, so she can just reach up to get air.
But I really do think she just needs some quiet time.
If she seems like she's getting worse, post again. :)
