Narrative:

On downwind for runway xx; aircraft was slowed to flap speed for visual approach. Flaps 1 was selected with normal leading edge device indications. When flaps 2 was selected; no trailing edge flaps extended. Followed ECAM and non-normal procedures and recycled flap handle position several times; from flaps up to flaps 3 positions and in between. [We] discussed diverting to a domestic airport as an alternate. Tower then had windshear report and decision was made to proceed to a domestic airport and land. Company; ATC and flight attendants/passengers were also advised. Prepared for full slats/no flap landing at our diversion airport and declared emergency and asked for equipment to stand by as precaution. If no slats/no flaps on final approach runway xxr; decision was made to divert to another nearby airport if necessary; for longer runway lengths. On final approach; both slats and flaps operated normally and landing was made and taxied to the gate.
