A sprinkler includes a tubular member having a longitudinal track and a number of water discharging openings formed through the track, and one or more shutoff control devices slidably attached onto the track and movable along the track to selectively align with either or some of the water discharging openings of the tubular member and to selectively block and seal the water discharging openings of the tubular member. The shutoff control devices each include a seat slidably attached to the track, and a latch pivotally attached to the seat for selectively blocking either of the water discharging openings of the tubular member and for controlling the water spraying patterns of the sprinkler.
